Pregnancy, childbirth, and sexual function: perceptions and facts

Abstract: Introduction and hypothesis Data on the effect of pregnancy and mode of delivery on postpartum sexual function are very heterogenic and inconclusive. The aim of this review is to examine the current literature for reliable data on the role of pregnancy and the route of delivery on sexual health and different dysfunctions.

Urinary bacteria in adult women with urgency urinary incontinence.

Abstract: Introduction and hypothesis This study’s aims were to detect and quantify bacterial DNA in the urine of randomized trial participants about to undergo treatment for urinary urgency incontinence (UUI) without clinical evidence of urinary tract infection (UTI) and to determine if the presence of bacterial DNA in baseline urine relates to either baseline urinary symptoms or UTI risk after urinary tract instrumentation.

National survey of perineal trauma and its subsequent management in the United Kingdom.

Abstract: Introduction and hypothesis Perineal trauma affects approximately 350,000 women per annum in the United Kingdom (UK) and is associated with considerable morbidity Symptoms are most severe following obstetric anal sphincter injuries (OASIS) compared with other grades of perineal trauma The Royal College of Obstetricians and Gynaecologists (RCOG) guidelines indicate that the rate of OASIS is 1 % of vaginal deliveries In 2011, the RCOG implemented the “Maternity Dashboard” so that units could benchmark their performance against national standards of which OASIS is a component Our primary objective was to establish the national rate of OASIS and audit variations in incidence and management of obstetric perineal trauma

What is clinically relevant prolapse? An attempt at defining cutoffs for the clinical assessment of pelvic organ descent.

Abstract: This study was undertaken to investigate the relationship between symptoms of prolapse and International Continence Society Pelvic Organ Prolapse Quantification (ICS POP-Q) measurements in order to establish optimal cutoffs for predicting prolapse symptoms using receiver operator characteristic (ROC) statistics. This was a retrospective study using 764 archived data sets of patients seen for symptoms of lower urinary tract and pelvic floor dysfunction between March 2011 and November 2012. Main outcome measure was symptoms of prolapse. Explanatory parameters were Ba, C, and Bp as defined by the ICS POP-Q. Patient age, body mass index (BMI), previous hysterectomy or incontinence/prolapse surgery, and vaginal parity were tested for a confounding effect on the relationship between ICS POP-Q measurements and symptoms of prolapse. Optimal cutoffs for predicting prolapse symptoms were defined as follows: Ba = –0.5 (sensitivity 69 %, specificity 71 %), C =−5 (sensitivity 67 %, specificity 64 %), Bp = −0.5 (sensitivity 63 %, specificity 62 %). ROC statistics resulted in an area under the curve of 0.768 for Ba [confidence interval (CI) 0.729–0.807), for C of 0.724 (CI 0.672–0.776), and for Bp of 0.686 (CI 0.639–0.733). Our findings suggest that the ICS POP-Q staging system requires revision. Prolapse of the anterior and posterior vaginal wall of < −1 should probably be regarded as normal. On the other hand, stage 1 uterine prolapse as currently defined seems highly relevant.

Psychosexual outcome after labiaplasty: a prospective case-comparison study.

Abstract: Our goal was to determine psychosexual outcome after labiaplasty in the long-term with specific measures of genital body image and sexual dysfunction. We conducted a prospective study with a matched-comparison group of women not wanting labiaplasty. Forty-nine women were compared against a group of 39 women matched for age, sexual orientation, ethnicity, and marital status. The labiaplasty group was assessed before, 3 months after and between 11 and 42 months after surgery. The comparison group was assessed at two time points 3 months apart to control for the passage of time. The primary outcome measure was the Genital Appearance Satisfaction (GAS) scale. Of the 49 women receiving labiaplasty, 19 (38.8 %) were lost to follow-up but were reassessed clinically. Twenty-four of 25 (96 %) women in the labiaplasty group showed a reliable and clinically significant improvement on the GAS scale 3 months after the procedure; 21/23 (91.3 %) showed an improvement at the long-term follow-up. A large effect size was found for improvements on the GAS scale in the labiaplasty group. Small-effect sizes were found for improvements in sexual functioning. Nine women obtaining labiaplasty met diagnostic criteria for body dysmorphic disorder before the operation; eight lost that diagnosis at the 3-month follow-up; 26 % reported minor side effects. Labiaplasty is effective in improving genital appearance and sexual satisfaction, but larger studies are required to determine the prevalence of potential side effects.

Iatrogenic genitourinary fistula: an 18-year retrospective review of 805 injuries

Abstract: Introduction and hypothesis Genitourinary fistula poses a public health challenge in areas where women have inadequate access to quality emergency obstetric care Fistulas typically develop during prolonged, obstructed labor, but providers can also inadvertently cause a fistula when performing obstetric or gynecological surgery

Changes in prolapse surgery trends relative to FDA notifications regarding vaginal mesh.

Abstract: Introduction and hypothesis In 2008 and 2011, the US Food and Drug Administration (FDA) released notifications regarding vaginal mesh. In describing prolapse surgery trends over time, we predicted vaginal mesh use would decrease and native tissue repairs would increase.

Long-term follow-up of laparoscopic sacrocolpopexy.

Abstract: This study evaluates the long-term results of laparoscopic sacrocolpopexy. In a prior publication, we demonstrated that laparoscopic sacrocolpopexy is a safe method with excellent anatomical results and low recurrence rates after a 12-month follow-up. This study now evaluates the long-term objectives and subjective outcomes of laparoscopic sacrocolpopexy after 5 years (mean). From 2003 to 2007, a prospective study enrolling 101 patients was conducted to evaluate laparoscopic sacrocolpopexy as a treatment for pelvic organ prolapse. The long-term results were assessed postoperatively after 5 years by gynecological examinations, including the Pelvic Organ Prolapse Quantification (POP-Q) system and quality of life assessments using validated questionnaires. A total of 68 patients received a full clinical follow-up exam between July and September 2011, and 17 patients were assessed by questionnaires only. Altogether, six anatomical recurrences in the anterior, four in the posterior, and one in the apical compartment were found during the 5 years after surgery; 83.8 % of patients had no prolapse in any compartment or stage 0 prolapse according to the International Continence Society (ICS) classification. The total reoperation rate was 3.5 %. Two mesh erosions into the bladder occurred, though no vaginal erosion occurred. The preoperative quality of life index improved from 5.6 to 9.1 (12 months) and 8.3 (60 months) postoperatively, resulting in a subjective cure rate of 95.3 %. Laparoscopic sacrocolpopexy has demonstrated excellent anatomical and functional long-term results. With the ongoing debate about the complications of vaginal mesh surgery, laparoscopic sacrocolpopexy should be considered a favorable treatment option for patients with pelvic organ prolapse.

Mechanical properties of pelvic soft tissue of young women and impact of aging.

Abstract: The female pelvic floor is a complex network of ligaments and muscles whose mechanical properties have not been completely understood. The goal of this study is to understand the biomechanical properties of the pelvic floor tissues of young women and the impact of aging. Biomechanical uniaxial tension tests were performed on pelvic floor tissues (ligaments and organs) of six young female cadavers (average 29 years old). Results have been analyzed in order to define the characteristics of the mechanical properties of young pelvic soft tissues. Results have been compared with those in the literature in order to understand the similarities and discrepancies between young and old patients. Damageable, nonlinear elastic biomechanical behavior is observed. The variation in stiffness among the pelvic floor organs could be shown. Ligaments and the vaginal wall are the most rigid organs, whereas the rectum and bladder tend to be less rigid (approximately two times less rigid for small deformations and three times less rigid for large deformations). This study shows that ligaments and the vaginal wall of young women have similar mechanical behavior while those of older women differ. Furthermore, young women’s tissues differ slightly from older women’s tissues. Results show that aging and possibly diverse “trauma” have an impact on modifying the mechanical behavior of pelvic floor tissues. Over time pelvic floor ligaments and vaginal tissues will differentiate and acquire different mechanical behavior, as seen within the literature in older cadavers.

UR-CHOICE: can we provide mothers-to-be with information about the risk of future pelvic floor dysfunction?

Abstract: Vaginal childbirth is probably the most important factor in the aetiology of pelvic floor dysfunction (PFD) and results in the combination of some or all of the following conditions: urinary (UI) and faecal (FI) incontinence and pelvic organ prolapse (POP). Up until now, it has been difficult to counsel women antenatally regarding risk factors for subsequent PFD, as there has been little good-quality, long-term information available. We now have moderately robust epidemiological data at 12 and 20 years after delivery and objective pathophysiological data (pudendal nerve trauma and levator defects/avulsion). In this commentary, we propose a scoring system (UR-CHOICE) to predict the risk of future PFD based on several major risk factors (UI before pregnancy, ethnicity, age at birth of first child, body mass index, family history (mother and sister) of PFD and baby's weight and maternal height (if 4 kg) that have been identified for subsequent PFD risk. This scoring system will help with counselling for women regarding PFD prevention.

Validation of the Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact Questionnaire (PFIQ-7) in a Dutch population

Abstract: The objective of this study was to validate the Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact Questionnaire (PFIQ-7) in Dutch women. Patients with pelvic floor dysfunction completed the Dutch questionnaires at (1) inclusion to evaluate internal consistency, (2) 1 week later to assess test-retest reliability, and (3) 6 months later to assess responsiveness and interpretability of change. To assess validity, floor and ceiling effects and construct validity were tested. A population-based sample (reference group) completed the questionnaires once. Data of 111 patients and 283 reference group participants were analyzed. Internal consistency of baseline scores in patient and reference groups was moderate (Cronbach’s alpha 0.52–0.60) to adequate in the PFDI-20 (Cronbach’s alpha 0.71–0.84) and adequate in the PFIQ-7 (Cronbach’s alpha 0.88–0.94). Both measures presented adequate test-retest reliability (intraclass correlation coefficient 0.79–0.91) and adequate responsiveness (area under the receiver-operating characteristic curve both 0.77). Interpretability was adequate for PFDI-20 and acceptable for PFIQ-7 with a clinically relevant minimally important change of −23 and −29 points, respectively. At baseline, the scales of the PFIQ-7 showed floor effects (44–55 %) in patients, though the PFIQ-7 summary score did not. No ceiling effects were observed. Construct validity was adequate with all predefined hypotheses confirmed regarding subgroup discrimination using pooled patient and reference group baseline data. For assessing distress and health-related quality of life of pelvic floor dysfunction, the Dutch PFDI-20 and PFIQ-7 are reliable and valid in the general Dutch population, and also responsive and interpretable among tertiary care-seeking women.

Incidence of female urethral diverticulum: a population-based analysis and literature review.

Abstract: Urethral diverticulum (UD) is a protrusion of the urethra through the periurethral fascia. We aimed to determine the population-based incidence of female UD. Using the records-linkage system of the Rochester Epidemiology Project (REP), we identified women 18 years and older with a new diagnosis of UD in Olmsted County, Minnesota, USA, from 1 January 1980, through 31 December 2011. We also identified cases meeting the same criteria diagnosed at Mayo Clinic, regardless of county of residency. Incidence rates were calculated and trends for changes in incidence over time were tested. We conducted a systematic search of the MEDLINE, EMBASE, Cochrane Systematic Reviews, CENTRAL, Web of Science, and Scopus databases from inception through 30 March 2013, to identify published reports of UD incidence or prevalence. We identified 164 incidence cases, including 26 women residing in Olmsted County. Age-adjusted annual incidence of UD in Olmsted County was 17.9 per 1,000,000 women (<0.02 %) per year (95 % CI, 10.9–24.9). We observed a trend toward increased incidence during the past 3 decades (P = 0.03). In our literature review, only 7 studies included an estimate of incidence or prevalence of UD; these estimates ranged from 6.4 per 1,000,000 per year (<0.01 %) having surgical intervention related to UD to a 4.7 % rate of UD diagnosed in asymptomatic women admitted for gynecological or obstetric issues. In this population-based study, female UD was a rare disease, affecting fewer than 20 per 1,000,000 women (<0.02 %) per year.

Dilation and surgical management in vaginal agenesis: a systematic review

Abstract: Introduction The management of vaginal agenesis is currently determined by geographical location and surgeon preference. The optimal treatment is unknown and the majority of articles on technique and outcome focus on personal case series with little standardisation of reporting and follow-up.

Management of pelvic organ prolapse and quality of life: a systematic review and meta-analysis

Abstract: Introduction and hypothesis One of the main outcomes in the assessment of the treatment of pelvic organ prolapse in women is quality of life. Using quality of life as an outcome measure is increasing in the majority of clinical trials. The aim of current study was to determine the effects of the treatment of pelvic organ prolapse on patients’ quality of life using systematic review and meta-analysis. Methods A systematic search for finding randomized controlled studies on pelvic organ prolapse published before October 2012 was conducted. The JAMA users’ guide to the medical literature quality assessment scales for randomized clinical trials was used to assess the quality of included articles. Themeandifferencein total qualityoflifescorebetweenbefore and after intervention (surgical or pelvic floor training) with 95 % confidence interval (CI) was considered as a primary summary measure. Egger’s test was used to evaluate the publication bias. Heterogeneity was assessed using I 2 Index. Results Fifty-seven RCT were critically appraised. Thirtytwo articles were eligible after critical evaluation. Mean difference in change in the total quality of life score with 95 % CI for surgical treatment was 74.03 (66.3–81.6) by PFDI-20 and was 44.57 (22.53–66.65) by PFIQ-7. The mean difference in changed in the total quality of life score with 95 % CI was 1.32 (�2.8–5.4) for pelvic floor training (PFT). Conclusion We found that surgical interventions on prolapse can improve the quality of life of women. There was a relative effect of PFT on the quality of life of women with prolapse in systematic review. This effect was not seen in meta-analysis, probably because of finding few eligible studies to pool the effect size.

Perceptions about female urinary incontinence: a systematic review.

Abstract: Introduction and hypothesis Perceptions about urinary incontinence (UI) may have a differential impact on treatment-seeking behaviors. Thus, we aimed to systematically review perceptions regarding UI in women of different racial and ethnic populations.

Postpartum urinary retention: a systematic review of adverse effects and management.

Abstract: Postpartum urinary retention (PUR) is a well-known condition after childbirth. Often clinicians assume that this condition is transient, either through belief or by not being aware that its occurrence as measurement of post-void residual volume (PVRV) is often not routine. However, long lasting urinary retention is a serious condition that needs management in order to prevent urogenital tract morbidity. By performing a systematic review of the adverse effects of PUR and management of this condition, we aimed to identify the necessity of diagnosing this condition in the puerperium and to evaluate whether treatment is required. We searched for all studies on PUR in OVID MEDLINE, OVID EMBASE, and ongoing Trial registers. Two reviewers independently screened and extracted the data. Twenty-four papers were included in this review. Limited data on adverse effects demonstrate potential morbidities, like micturition symptoms and sporadically spontaneous bladder ruptures, related to PUR. Based on current literature, evidence stating that PUR is harmless is lacking. Future research should focus on management strategies for overt PUR and the long-term consequences of covert PUR. Until these results are available, clinicians should be aware of the potential consequences and therefore keep trying to identify patients at risk of PUR and patients with the actual condition.

Understanding and treating vaginismus: a multimodal approach

Abstract: This clinical opinion was written to bring attention to the understanding and treatment of vaginismus, a condition that is often under diagnosed and therefore inadequately treated, yet affects millions of women worldwide. Despite its description more than a century ago, vaginismus is rarely taught in medical school, residency training, and medical meetings. The DSM 5 classification stresses that vaginismus is a penetration disorder in that any form of vaginal penetration such as tampons, finger, vaginal dilators, gynecological examinations, and intercourse is often painful or impossible. Compared with other sexual pain disorders such as vulvodynia and vestibulodynia, the treatment of vaginismus has the potential for a high rate of success. Stratifying the severity of vaginismus allows the clinician to choose among numerous treatment options and to better understand what the patient is experiencing. Vaginismus is both a physical and an emotional disorder. In the more severe cases of vaginismus women (and men) complain that attempted intercourse is like "hitting a wall" suggestive of spasm at the level of the introitus. The emotional fallout resulting from this needs to be addressed in any form of treatment applied. This article is based on lessons learned in the treatment of more than 250 patients and evaluation of more than 400 inquiries, and was written to make vaginismus more widely understood, to aid in the differential diagnosis of sexual pain, suggest a variety of effective treatments, and explain how Botox can be used as part of a multimodal treatment program to treat vaginismus. With greater awareness among clinicians it is hoped that medical schools, residency programs, and medical meetings will begin teaching the understanding and treatment of vaginismus.

Subjective and objective results 1 year after robotic sacrocolpopexy using a lightweight Y-mesh

Abstract: Introduction and hypothesis The objective of this study was to assess outcomes following robotic sacrocolpopexy using a lightweight polypropylene Y-mesh. Methods During our study period, all patients who underwent robotic sacrocolpopexy were enrolled in this single-arm prospective trial. Endpoints included Pelvic Organ Prolapse Quantification (POP-Q) values; Pelvic Floor Distress Inventory, short form 20 (PFDI-20); Pelvic Floor Impact Questionnaire, short form 7 (PFIQ-7); Surgical Satisfaction scores; and the Sandvik Incontinence Severity Index. All surgeries were performed with a pre-configured monofilament type 1 polypropylene Y-mesh (Alyte©, C.R. Bard, Covington, GA, USA). Cure rates at 12 months were calculated using two separate definitions: (1) “clinical cure”: no POP-Q points>0, point C ≤− 5, no prolapse symptoms on the PFDI-20, and no reoperations for prolapse and (2) “objective anatomic cure”: POP-Q stage 0 or 1, point C of ≤− 5, and no reoperations for prolapse. Results A total of 150 patients underwent robotic sacrocolpopexy and 143 (95 %) were available for 12-month follow-up. Mean age was 58.6 ± 9.8 and mean body mass index was 26.3 ± 4.5. Mean operative time and blood loss were 148±27.6 min (range 75–250 min) and 51.2±32, respectively. There were no mesh erosions or exposures, and meshedgeswerenot palpableinanypatient.At12monthsthe clinical cure rate was 95 %, and the objective anatomic cure rate was 84 %. The PFDI-20 mean score improved from 98 at baseline to 17 at 12 months (p<0.0001); PFIQ-7 scores improved from 59 to 6.5 (p<0.0001). Conclusions Robotic sacrocolpopexy using this lightweight polypropylene Y-mesh offers excellent subjective and objective results at 1 year.

Prevalence, etiology and risk factors of pelvic organ prolapse in premenopausal primiparous women.

Abstract: The natural history of pelvic organ prolapse (POP) is poorly understood. We investigated the prevalence and risk factors of postnatal POP in premenopausal primiparous women and the associated effect of mode of delivery. We conducted a prospective cohort study in a tertiary teaching hospital attending 9,000 deliveries annually. Collagen-diseases history and clinical assessment was performed in 202 primiparae at ≥1 year postnatally. Assessment included Pelvic Organ Prolapse Quantification (POP-Q) system, Beighton mobility score, 2/3D-transperineal ultrasound (US) and quantification of collagen type III levels. Association with POP was assessed using various statistical tests, including logistic regression, where results with p < 0.1 in univariate analysis were included in multivariate analysis. POP had a high prevalence: uterine prolapse 89 %, cystocele 90 %, rectocele 70 % and up to 65 % having grade two on POP-Q staging. The majority had multicompartment involvement, and 80 % were asymptomatic. POP was significantly associated with joint hypermobility, vertebral hernia, varicose veins, asthma and high collagen type III levels (p < 0.05). In multivariate logistic regression, only levator ani muscle (LAM) avulsion was significant in selected cases (p < 0.05). Caesarean section (CS) was significantly protective against cystocele and rectocele but not for uterine prolapse. Mild to moderate POP has a very high prevalence in premenopausal primiparous women. There is a significant association between POP, collagen levels, history of collagen disease and childbirth-related pelvic floor trauma. These findings support a congenital contribution to POP etiology, especially for uterine prolapse; however, pelvic trauma seems to play paramount role. CS is significantly protective against some types of prolapse only.

Pyogenic spondylodiscitis associated with sacral colpopexy and rectopexy: report of two cases and evaluation of the literature

Abstract: Pyogenic spondylodiscitis includes a spectrum of spinal infections such as discitis, osteomyelitis, epidural abscess, meningitis, subdural empyema, and spinal cord abscess. This is a rare complication of sacral colpopexy, but can lead to devastating consequences for the patient. We present two cases of pyogenic spondylodiscitis following sacral colpopexy. In addition, we discuss 26 cases of pyogenic spondylodiscitis reported in the literature from 1957 to 2012. Techniques to decrease rates of infection include proper identification of the S1 vertebra, awareness of the suture placement depth at the level of the sacrum and at the vagina, and early treatment of post-operative urinary tract and vaginal infections. Awareness of symptoms, timely diagnosis and multidisciplinary approach to management is essential in preventing long-term complications.

Laparoscopic hysteropexy: 1- to 4-year follow-up of women postoperatively

Abstract: Uterine conserving re-suspension surgery has become more popular in recent years. Such surgery may allow preservation of fertility in younger women, but may also have the added benefit of augmenting weak connective tissue and possibly providing stronger apical support than the conventional hysterectomy. Our goal was to evaluate the 1- to 4-year outcome of laparoscopic hysteropexy for the surgical management of uterine prolapse. This study was a prospective observational study of 182 consecutive women who underwent laparoscopic hysteropexy, with or without additional vaginal repair, from the beginning of 2007 until the end of 2010. Women were invited to attend a dedicated clinic for interview and their prolapse was assessed using the Patient Global Impression of Improvement (PGI-I), the International Consultation on Incontinence Questionnaire for Vaginal Symptoms (ICIQ-VS) and the pelvic organ prolapse quantification (POP-Q) scale. Wilcoxon signed-rank test was used to compare pre-operative with postoperative data. Complications and women’s satisfaction were also noted. One hundred and forty women agreed to participate; the mean interval from operation was 2.1 years (range 1–4.4). Eighty-nine percent of women felt that their prolapse is “very much” or “much” better using PGI-I subjective outcome measure. There was significant improvement for all parameters of ICIQ-VS and POP-Q scoring post-surgery (p < 0.001). Six women (4 %) had further apical prolapse; of these, 3 underwent further prolapse surgery. None of the participants had any mesh exposure. Ninety two percent of participants would recommend the operation. Laparoscopic hysteropexy is a safe and effective treatment. The 1- to 4-year outcome suggests high patient satisfaction and low rates of apical prolapse recurrence. Longer term follow-up and randomized controlled studies are required.

A multicentre, prospective, randomised, double-blind study to measure the treatment effectiveness of abobotulinum A (AboBTXA) among women with refractory interstitial cystitis/bladder pain syndrome.

Abstract: Introduction and hypothesis To determine if abobotulinumtoxin A (AboBTXA) is an effective treatment for interstitial cystitis/bladder pain syndrome (IC/BPS).

Transcutaneous posterior tibial nerve stimulation: evaluation of a therapeutic option in the management of anticholinergic refractory overactive bladder.

Abstract: This study evaluated the efficacy and tolerability of transcutaneous posterior tibial nerve stimulation (TPTNS) in the treatment of overactive bladder (OAB) after failure of a first-line anticholinergic treatment. We performed a prospective observational study and included all patients treated in a single center for OAB persisting after first-line anticholinergic treatment from November 2010 to May 2013. The protocol consisted of daily stimulation at home. The efficacy end point was defined as improvement on the Urinary Symptom Profile (USP) and the French-validated urinary symptom score Mesure du Handicap Urinaire (MHU). We assessed 43 consecutive patients. TPTNS was successful following 1 month of treatment in 23 (53 %) patients. Bladder capacity was the only predictive factor for treatment success (p = 0.044). For patients who showed improved symptoms (n = 23; 53 %), mean MHU and USP decreased significantly, from 11.8 ± 2.8 to 5.6 ± 3 (p < 0.001) and from 14 ± 3.3 to 6.9 ± 3.2 (p < 0.001), respectively. After a mean follow-up of 10.8 ± 1.6 months, 21 (49 %) patients continued the TPTNS. Mean MHU and USP scores were 4.4 ± 2.8 and 5.4 ± 3.5, respectively, and stayed lower than baseline (p < 0.001). Patients reported no adverse events. TPTNS is well tolerated and is effective in one half of the patients studied after they failed anticholinergic treatment. TPTNS could become a second therapeutic option before surgical treatment in the management strategy of OAB.

Do women notice the impact of childbirth-related levator trauma on pelvic floor and sexual function? Results of an observational ultrasound study.

Abstract: The levator ani is thought to play an important role in sexual function; however, to date little literature has been published on the impact of delivery–related levator trauma on female sexual function. We hypothesised that delivery-related levator trauma has a negative impact on women’s reports of pelvic floor and sexual function postpartum. In 294 primigravid women with a singleton pregnancy, four-dimensional (4D) translabial ultrasound imaging was used to assess delivery–related levator avulsion and levator hiatal over-distension, and postpartum pelvic floor and sexual function was assessed by an in-house validated questionnaire. Associations between questionnaire responses and levator avulsion and hiatal over-distension were investigated using standard linear modelling methods. Levator avulsion was diagnosed in 14 % of women (42 out of 292; 25 unilateral, 17 bilateral) and was found to be significantly associated with lower scores for the pelvic floor integrity and function domain of the questionnaire (P < 0.0005). Avulsion was associated with lower scores for this domain (no avulsion = 2.78, unilateral avulsion = 2.61, bilateral avulsion = 2.29). This association remained significant after controlling for potential confounders (p = 0.013). Avulsion was not associated with any of the other domains of sexual function and levator hiatal over-distension was not associated with scores for any of the questionnaire domains. The effect of levator avulsion on pelvic floor and sexual function an average of 5.2 months after childbirth seems to be limited to a perception of increased vaginal and pelvic floor muscle laxity, and reduced pelvic floor muscle efficiency. The impact of levator hiatal over-distension on postpartum pelvic floor and sexual function appears to be negligible.

Analysis of the learning process for laparoscopic sacrocolpopexy: identification of challenging steps

Abstract: We earlier demonstrated that the operation time of laparoscopic sacrocolpopexy (LSCP) by an experienced surgeon drops significantly after 30 cases to reach a steady state after 90. We now aimed to define the learning curve and to identify the most challenging steps for a trainee learning LSCP. Prospective consecutive series of 60 patients undergoing LSCP performed by a trainee experienced in operative laparoscopy but not LSCP. Prior to the first case, the trainee primed his endoscopic suturing skills on an endotrainer for 15 h. His operation time and performance score were analysed using moving average analysis (MOA). The former and the occurrence of complications or short-term failures were compared with those of a concurrent control group consisting of patients operated on by a surgeon experienced in LSCP (teacher). The procedure was empirically divided into five consecutive steps (dissection of the promontory, the paracolic gutter and vagina, suturing of the mesh to the vault, stapling to the promontory, and peritonealisation). The MOA of the operation time demonstrated a learning curve for all steps, except for the dissection of and fixation to the promontory. The most time-consuming step is the dissection of the vault, for which it took the trainee 31 procedures to achieve an operation time comparable to that of the teacher. Also, the quality of the dissection improved over time. Suturing of the implant to the vault and peritonealisation took only 10 and 6 procedures respectively. There was no difference in the occurrence of major complications and in one case the trainee asked for assistance. Quality of LSCP improves with experience. Operation time falls as well, and the most time-consuming step is the dissection of the paracolic and perivaginal spaces. Prior training in laparoscopic suturing coincided with a short learning process for the phases requiring suturing.

Dutch guidelines for physiotherapy in patients with stress urinary incontinence: an update.

Abstract: Stress urinary incontinence (SUI) is the most common form of incontinence impacting on quality of life (QOL) and is associated with high financial, social, and emotional costs. The purpose of this study was to provide an update existing Dutch evidence-based clinical practice guidelines (CPGs) for physiotherapy management of patients with stress urinary incontinence (SUI) in order to support physiotherapists in decision making and improving efficacy and uniformity of care. A computerized literature search of relevant databases was performed to search for information regarding etiology, prognosis, and physiotherapy assessment and management in patients with SUI. Where no evidence was available, recommendations were based on consensus. Clinical application of CPGs and feasibility were reviewed. The diagnostic process consists of systematic history taking and physical examination supported by reliable and valid assessment tools to determine physiological potential for recovery. Therapy is related to different problem categories. SUI treatment is generally based on pelvic floor muscle exercises combined with patient education and counseling. An important strategy is to reduce prevalent SUI by reducing influencing risk factors. Scientific evidence supporting assessment and management of SUI is strong. The CPGs reflect the current state of knowledge of effective and tailor-made intervention in SUI patients.

Modeling manual perineal protection during vaginal delivery

Abstract: We compared hands-on manual perineal protection (MPP) and hands-off delivery techniques using the basic principles of mechanics and assessed the tension of perineal structures using a novel biomechanical model of the perineum. We also measured the effect of the thumb and index finger of the accoucheur’s dominant-posterior hand on perineal tissue tension when a modified Viennese method of MPP is performed. Hands-off and two variations of hands-on manual perineal protection during vaginal delivery were simulated using a biomechanical model, with the main outcome measure being strain/tension throughout the perineal body during vaginal delivery. Stress distribution with the hands-on model shows that when using MPP, the value of highest stress was decreased by 39 % (model B) and by 30 % (model C) compared with the hands-off model A. On the cross section there is a significant decrease in areas of equal tension throughout the perineal body in both hands-on models. Simulation of the modified Viennese MPP significantly reduces the maximum tension on the inner surface of the perineum measured at intervals of 2 mm from the posterior fourchette. In a biomechanical assessment with a finite element model of vaginal delivery, appropriate application of the thumb and index finger of the accoucheur’s dominant-posterior hand to the surface of the perineum during the second stage of delivery significantly reduces tissue tension throughout the entire thickness of the perineum; thus, this intervention might help reduce obstetric perineal trauma.

Impact of levator trauma on pelvic floor muscle function.

Abstract: Levator trauma is common after vaginal delivery, either as macrotrauma, i.e., levator avulsion, or microtrauma, i.e., irreversible overdistension of the levator hiatus. The effect of microtrauma on muscle function is unknown. We tested the hypothesis that levator trauma is associated with reduced contractile function of the levator ani. Pregnant nulliparous women were recruited and seen before and after childbirth. All underwent an interview, a clinical examination including pelvic floor muscle (PFM) assessment using the Modified Oxford scale (MOS) [as an optional component] and translabial ultrasound. Sonographic and clinical parameters of PFM function were assessed before and after childbirth. Out of 560 women, 446 returned at a median of 5 months after childbirth and 433 were suitable for analysis. There was a significant reduction in all measures of PFM function except for MOS. Change in MOS was associated with delivery mode [analysis of variance (ANOVA) P = 0.006). Forty-seven (15 %) vaginally parous women were diagnosed with levator avulsion, which was associated with a reduction in PFM contractility on sonographic parameters and MOS. However, only clinical assessment reached statistical significance. Sixty-five of 312 (21 %) women were diagnosed with microtrauma. We found no evidence of impairment in PFM contractility on ultrasound, but there was a statistically significant reduction in MOS. Both levator avulsion (macrotrauma) and irreversible overdistension (microtrauma) are associated with reduced contractile function. This effect is more easily detected by palpation than by sonographic indices of levator function.

Comparison of muscle fiber directions between different levator ani muscle subdivisions: in vivo MRI measurements in women

Abstract: This study describes a technique to quantify muscle fascicle directions in the levator ani (LA) and tests the null hypothesis that the in vivo fascicle directions for each LA subdivision subtend the same parasagittal angle relative to a horizontal reference axis. Visible muscle fascicle direction in the each of the three LA muscle subdivisions, the pubovisceral (PVM; synonymous with pubococcygeal), puborectal (PRM), and iliococcygeal (ICM) muscles, as well as the external anal sphincter (EAS), were measured on 3-T sagittal MRI images in a convenience sample of 14 healthy women in whom muscle fascicles were visible. Mean ± standard deviation (SD) angle values relative to the horizontal were calculated for each muscle subdivision. Repeated measures ANOVA and post-hoc paired t tests were used to compare muscle groups. Pubovisceral muscle fiber inclination was 41 ± 8.0°, PRM was −19 ± 10.1°, ICM was 33 ± 8.8°, and EAS was −43 ± 6.4°. These fascicle directions were statistically different (p < 0.001). Pairwise comparisons among levator subdivisions showed angle differences of 60° between PVM and PRM, and 52° between ICM and PRM. An 84° difference existed between PVM and EAS. The smallest angle difference between levator divisions was between PVM and ICM 8°. The difference between PRM and EAS was 24°. All pairwise comparisons were significant (p < 0.001). The null hypothesis that muscle fascicle inclinations are similar in the three subdivisions of the levator ani and the external anal sphincter was rejected. The largest difference in levator subdivision inclination, 60°, was found between the PVM and PRM.

Mixed urinary incontinence: international urogynecological association research and development committee opinion.

Abstract: The definition as well as the treatment of women with mixed urinary incontinence (MUI) is controversial. Since women with MUI are a heterogeneous group, the treatment of MUI requires an individual assessment of the symptom components: stress urinary incontinence, urinary urgency, urgency urinary incontinence, urinary frequency, and nocturia. The purpose of this paper is to summarize the current literature and give an evidence-based review of the assessment and treatment of MUI. A working subcommittee from the International Urogynecological Association (IUGA) Research and Development (RD if surgery is contemplated, urodynamic investigation is recommended. Women undergoing surgical treatment for MUI need to be counselled about the possibility of persistence of urinary urgency, frequency and urge incontinence even if stress urinary incontinence is cured.
