A Systematic Review of Medical Therapy to Facilitate Passage of Ureteral Calculi

Purpose: PCNL (percutaneous nephrolithotripsy) is usually performed in the prone position. The supine position has potential advantages comparing with the prone position. Our objective is comparison between the outcome of PCNL in the complete supine position and the standard prone position. Material and Methods: A total of 80 patients who underwent PCNL from February 2008 to June 2008 evaluated in a prospective manner, were randomly divided into two groups: 40 patients underwent prone PCNL and 40 patients underwent complete supine PCNL. We performed complete supine PCNL with no rolled towel under the flank and no change in leg position. Results in both positions were compared regarding technical aspects, operative time, stone free rate, complications and hospital stay, and were analyzed using t-test and chi–square. We considered P < 0.05 as significant. Results: Regardless the position, the pelvicaliceal system could be successfully approached in all patients. Mean operative time in supine group was 74.7 ...

Introduction: Our aim was to investigate the diagnostic accuracy of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) in patients with acute scrotum. Materials and Methods: One hundred and twenty patients with acute scrotum were evaluated and divided into 3 groups: 46 with acute epididymitis (group 1), 23 with spermatic cord torsion (group 2), and 51 with other noninflammatory causes of acute scrotum (group 3). Serum levels CRP and ESR were measured at the time of admission. Results: Of the patients in group 1, 44 (95.6%) had elevated serum levels of CRP (mean, 67.77 ± 47.80 mg/L). In contrast, only 1 patient in group 2 had a significant increase in the serum level of CRP (mean, 9.0 ± 4.90 mg/L), and the patients in group 3 did not have any significant increase in the CRP levels (mean, 7.0 ± 2.2 mg/L) (P < .001). The mean ESR values were 45.9 ± 21.4 mm/h, 14.2 ± 11.2 mm/h, and 8.8 ± 7.5 mm/h, in groups 1 to 3, respectively (P < .001). The cutoff points for distinguishing between epididymitis and noninflammatory causes of acute scrotum were 24 mg/L for CRP and 15.5 mm/h for ESR. The sensitivity and specificity values were 93.4% and 100% for CRP and 95.6% and 85.1% for ESR, respectively. Conclusion: Based on our findings, serum levels of CRP and ESR can provide helpful information for differentiation between epididymitis and other causes of acute scrotum. We recommend CRP and ESR measurements before making a decision of surgical intervention.

PURPOSE: To compare the immediate effects of a systemic nitric oxide (NO) donor with placebo on the uroflowmetric parameters in patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Eighty patients with the mean age of 61.5 years (range, 49 to 74 years) who suffered from BPH were enrolled in the study. We examined peak flow rate, average flow rate, and residual urine in all the patients. Then, patients were randomized to receive either 20 mg sublingual isosorbide dinitrate (ISDN) (n = 40) or placebo (n = 40) 20 minutes prior to the second uroflowmetry, which was performed one day after the first test. RESULTS: The mean peak flow rate increased from 7.6 Â± 0.41 mL/s to 10.2 Â±
0.54 mL/s (P = .013) in the ISDN group, while it increased +0.40 mL/s in the placebo group (P > .05). Mean residual urine volume decreased significantly from 51 Â± 3.1 mL to 29 Â± 2.9 mL and from 56 Â± 4.1 to 51 Â± 2.6 in the ISDN (P = .02) and the placebo groups (P > .05), respectively. At baseline, the mean arterial pressure was 95 Â± 2.1 mmHg and under the influence of the NO-donor, it decreased to 83 Â± 1.9 mmHg, which was significant (P < .001). No significant changes of micturition parameters were found in the placebo group. CONCLUSION: Organic nitrates influence micturition parameters in patients with BPH. This new approach could offer a potential pharmacological option to treat obstructive lower urinary tract symptoms.

Effects of isosorbide dinitrate on the urinary flow rate in patients with benign prostatic hyperplasia.

Received October 2008 Accepted February 2009 INTRODUCTION Fibroepithelial polyps (FEPs) of the urethra are rare lesions in adults and are most frequently seen in men during the first decade of life.(1) These lesions are benign and congenital, usually discovered in infants and children, and have rarely been reported in adults.(2,3) Solitary polyps are called different names, such as prostatic urethral polyps, FEPs of the urethra, or benign urethral polyps.(4) Because of their location, as they achieve larger size, they can produce a variety of urinary symptoms including dysuria, hematuria, urinary tract infections, and obstructive symptoms, which may progress to urinary retention.(5) We report a case of benign FEP of the prostatic urethra in a 20-year-old man who presented with obstructive urinary symptoms and urinary retention.
