Diagnosis of UTI: results of an evidence based approach to guideline development carried out for the National Institute for Health and Clinical Excellence (NICE)

Background: Uncomplicated lower urinary tract infections (UTIs) occur in approximately 50% of women, and 20–30% experience recurrent UTI. Data on UTIs and quality of life (QoL) in Europe are limite...

Social and economic burden of recurrent urinary tract infections and quality of life: a patient web-based study (GESPRIT)

Aims To assess the efficacy and safety of mirabegron in the treatment of neurogenic detrusor overactivity. Methods This prospective, multicenter, randomized, double-blind, placebo-controlled study was conducted in three tertiary centers, and included 78 patients suffering from spinal cord injury or multiple sclerosis. Patients were randomized for Mirabegron 50 mg (Group A) or placebo (Group B). Urodynamic parameters, the 24 h pad-weight test, and patient-reported outcomes were assessed. Safety assessments included monitoring the incidence and severity of adverse events. Changes in time and differences between groups were assessed with nonparametric Kruskal-Wallis one-way analysis of variance; P ≤ 0.05 was considered statistically significant. Results In total, 66 patients were eligible for inclusion in the final analysis. There was a significant increase of volume at the first detrusor contraction (P = 0.00047) and an improvement in bladder compliance (P = 0.0041) in the mirabegron group compared with the placebo-treated group, whereas the increase in cystometric capacity did not reach statistical significance (P = 0.061). There was a clear tendency to reduced urine leakage (P = 0.056) in Group A. There were significant changes in all the patient-reported outcomes, favoring the mirabegron group. The incidence of drug-related adverse events was 3.13%. Conclusions Mirabegron (50 mg) improved both urodynamic variables and patient-reported outcomes in patients with NDO. The treatment was tolerated well.

Efficacy and safety of mirabegron for the treatment of neurogenic detrusor overactivity-Prospective, randomized, double-blind, placebo-controlled study.

Objective: To evaluate the correlation between constipation and lower urinary tract dysfunction (LUTD) and nocturnal enuresis in a population-based study. Material and Methods: This is a cross-sectional study. The criteria for inclusion were: children and adolescents of between 5 and 17 years and who agreed to sign the informed consent form. The study excluded students with neurological problems or who had documented abnormalities of the urinary tract. To identify the presence and severity of LUTD, we used the Voiding Dysfunction Symptom Score (DVSS). To evaluate the presence of constipation, Rome III questionnaire was used. Results- We interviewed 829 children and adolescents, of which 416 (50.18%) were male. The mean (SD) age was 9.1 (± 2.9) years. The overall prevalence of LUTD was 9.1%, predominantly in girls (15% versus 3.1%, p < 0.001). Constipation was found in 9.4% of boys and 12.4% of girls (p = 0.169). Constipated children were 6.8 times more likely to have LUTD than those not constipated (p < 0.001, coefficient and correlation of 0.411). Constipation was found in 8.2% of children without LUTD and in 35.2% of children with LUTD. We performed multivariate analysis to identify urinary symptoms that are independent predictors of the presence of constipation. The presence of infrequent urination (p = 0.004) and holding maneuvers (p < 0.001) were independent predictors. It was noted also that constipated children, according to the Rome III criteria, possess a worse DVSS (p < 0.001). Regarding the presence of nocturnal enuresis, 12.6% of children and adolescents had constipation in association with this symptom. However, this relationship was not statistically significant (p = 0.483). Conclusion- Constipated children were 6.8 times more likely to have LUTD than those not constipated. Among the urinary symptoms, infrequent voiding and holding maneuvers are independent factors of urinary expressions in constipated children. Children with more severe constipation have more prominent urinary symptoms. The presence of enuresis was not associated to constipation.

Constipation and Lower Urinary Tract Dysfunction in Children and Adolescents: A Population-Based Study.

Little information is available on the recurrent coexistence of pelvic organ prolapse (POP), urinary (UI) and/or anal (AI) incontinence and defecatory dysfunctions and the relationship between these disorders. The purpose of this study is to report the prevalence, bother, and impact on quality of life (QoL) of unreported bowel symptoms in women presenting to a Brazilian tertiary urogynecology clinic. The study was a cross-section survey of 172 patients with symptoms of pelvic floor disorders (PFD). Patients who reported any defecatory and/or continence disorders were included in the study group, and the others were included in the control group. Patients with UI were also compared with those with double incontinence (DI): AI and UI. Univariate analysis was conducted using the Mann–Whitney U test for continuous nonparametric data. After the interview, 54.6 % (n = 94) of patients presented AI and/or defecatory disorders: 67.0 % constipation, 41.4 % AI, and 34.0 % fecal urgency. Women from the study group scored worse in the QoL questionnaires compared with women from the control group. Among women with UI, 23.21 % had associated AI. Women with DI scored worse in the QoL questionnaires. Anal and urinary dysfunctions are usually associated and have a great impact on a woman’s QoL. An integrated approach across specialties should lead to improved patient care. Therefore, our study is relevant because it emphasizes the importance of urogynecologists routinely investigating such symptoms. To do so, standardized questionnaires should be included in the evaluation of all these patients.

Prevalence of unreported bowel symptoms in women with pelvic floor dysfunction and the impact on their quality of life

CONTEXT: Urinary bladder and rectum share a common embryological origin. Their autonomic and somatic innervations have close similarities. Moreover, the close proximity of these two organ systems could suggest that dysfunction in one may influence, also mechanically, the function of the other. Therefore, it is not surprising that defecation problems and lower urinary tract symptoms (LUTS) occur together, as reported in the literature. OBJECTIVE: To study the relationship between constipation and LUTS focusing on what is evidence-based. EVIDENCE ACQUISITION: We searched the Medical Literature Analysis and Retrieval System Online (MEDLINE) database in February 2010 to retrieve English language studies (from 1997 to 2009) and the 2005, 2006 and 2007 abstract volumes of the European Association of Urology (EAU), American Urological Association (AUA) and International Continence Society (ICS). EVIDENCE SYNTHESIS: We present the findings according to the studied population in four groups: (a) children, (b) middle-aged women, (c) elderly and (d) neuropathic patients. Most published studies that correlated rectal and bladder dysfunction were carried out in children or in young women. On the other hand, there are few studies regarding the association between constipation and LUTS in the elderly and in neuropathic patients. CONCLUSIONS: Several studies in children documented that constipation is linked to urinary tract problems, including infections, enuresis, vesicoureteral reflux and upper renal tract dilatation. The underlying pathophysiology of these findings has not yet been clearly defined. Studies in middle-aged women also support a high prevalence of constipation among patients suffering from urinary tract dysfunction. Furthermore, an association between constipation and urinary incontinence, as well as between constipation and pelvic organ prolapse, has been suggested. The only prospective study in constipated elderly with concomitant LUTS demonstrates that the medical relief of constipation also significantly improves LUTS. Finally, the available data on neuropathic patients suggest that stool impaction in the rectum may mechanically impede bladder emptying. However, most of the studies only include a small number of patients, are not prospective and are uncontrolled. Therefore, there is a need for large-scale, controlled studies to further improve evidence and to provide a valid recommendation for all groups, especially for the elderly and neuropathic patients.

The impact of different scenarios for intermittent bladder catheterization on health state utilities: results from an internet-based time trade-off survey.

Purpose To estimate gains in health utility for two different catheter features and a support service related to urinary catheters used for intermittent catheterization. Patients and methods Two internet-based time trade-off (TTO) surveys were undertaken to value vignettes describing two innovative catheter features and a support service. The first TTO survey "Size and Service" included catheters with compact design and the availability of a support service for users; the second TTO survey "Phthalates" included avoidance of potentially harmful phthalates in the material of the catheters. All participants were from the UK; they traded health states against a time horizon that matched their total life expectancy. Sensitivity analyses were done to estimate the impact of extreme values on disutilities. Results The participants (n=890) estimated the incremental value of 0.031 (95% CI: 0.024-0.039), 0.009 (95% CI: 0.003-0.015), and 0.037 (95% CI: 0.027-0.046), respectively, for catheters with compact design, availability of support service, and catheters not containing phthalates. Conclusions Participants valued all three improvements in catheter design. To capture the impact of such design improvements on quality of life and utilities, vignette-based approaches can be a useful supplement to the conventional, generic tools.

Gains in health utility associated with urinary catheter innovations.

A targeted history and physical examination are the mainstays for basic evaluation of neurourological patients. Urodynamics investigations are of paramount importance in providing information about the pressure situation in the lower urinary tract (LUT). Pressures are crucial not only for LUT but also for upper urinary tract function. Regular ultrasound assessment is advisable but cannot replace invasive urodynamics.
