RESUMO
PURPOSE: In this placebo-controlled trial, we aimed to evaluate the clinical results of using PDE-5 inhibitor, tadalafil 5 mg OD, for management of CP/CPPS. PATIENTS AND METHODS: 140 patients ≤ 45 years old with moderate/severe CP/CPPS associated with ED (IIEF-5 < 22) were randomly divided and received either tadalafil 5 mg OD (tadalafil-group) or placebo (control-group) for 6 weeks. Post-treatment CPSI scores were compared to baseline and to placebo. Clinically significant responders (≥ 25% reduction from baseline score) were calculated. Tadalafil-induced changes in IIE-5 were evaluated in correlation to that of CPSI scores. RESULTS: By the 6th week, 59 and 56 patients were available in both groups respectively. Compared to baseline, tadalafil-group patients showed significant improvement in total, pain, urinary and Qol domains of CPSI (19.1 ± 5.26, 10.42 ± 3.55, 4.2 ± 1.72 and 4.47 ± 1.64 vs. 24.21 ± 5.05, 12.14 ± 3.57, 6.08 ± 1.53 and 6.22 ± 1.76), p < 0.5. When compared to placebo, all 6th week CPSI domains scores, except for pain, were significantly better in tadalafil-group (p < 0.05). Post-treatment pain score didn't significantly differ between both groups (10.42 ± 3.55, vs. 11.71 ± 3.9, p > 0.05). Clinically significant responders were 30 patients (50.8%) in tadalafil-group vs. 3 patients (5.4%) in control. Tadalafil-induced changes in IIEF-5 score had weak but significant correlation to Qol domain (r = - 0.28, p < 0.05). CONCLUSION: Tadalafil 5 mg OD can significantly improve all CPSI domains as compared to baseline. Post-treatment CPSI scores, except for pain, were better than placebo. About 50.8% of patients can develop ≥ 25% reduction in their total CPSI scores after treatment. Apart from Qol domain, these changes are not significantly correlated to tadalafil-induced IIEF-5 scores changes.

PURPOSE: To compare the results of dorsal dartos flap rotation versus suturing tunica albuginea to the pubic periosteum for correction of congenital penile torsion. PATIENTS AND METHODS: Seventeen patients with congenital penile torsion were evaluated and managed from 2006 to 2010. On a random basis, 9 patients underwent surgical repair using a dorsal dartos flap rotation technique (group 1), and 8 patients by suturing tunica albuginea to the pubic periosteum (group 2). All were followed up every 6 months. RESULTS: The mean age in group 1 was 52.3 ± 24.8 months, while in group 2 it was 53.4 ± 33.6 months. Mean follow up was 22.3 ± 10.2 and 21.5 ± 7.2 months in group 1 and group 2 respectively. Torsion was corrected in 6 (66.7%) patients of group 1; 3 (33.3%) had residual torsion < 10°. In group 2, correction was achieved in 6 (75.0%) patients and 2 (25.0%) had residual torsion < 10°. The mean operative time was significantly less for group 1 than for group 2: 45.3 ± 7.1 and 74.5 ± 5.3 min, respectively (P < 0.0001). CONCLUSIONS: In short-term prepubertal follow up, both dorsal dartos flap rotation and suturing tunica albuginea to the pubic periosteum are effective for correction of congenital penile torsion. The former technique is easier to perform as it requires much less dissection.

OBJECTIVE: To compare the prostatic resistive index (RI) and measurements from pressure-flow studies (PFS) for the diagnosis and follow-up of bladder outlet obstruction (BOO) in patients with benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: In all, 338 men (aged 55-82 years) presenting with lower urinary tract symptoms were evaluated prospectively for BOO secondary to BPH. In all patients, the prostatic RI was measured by transrectal power Doppler ultrasonography. PFS were assessed in all patients and depending on the results the patients were divided into an obstructive and an unobstructive group. The receiver operating characteristic (ROC) curve was used to determine the prostatic RI threshold value for predicting BOO secondary to BPH. Patients who were confirmed to have BOO secondary to BPH received either medical or surgical treatment, and they were re-evaluated after 3 and 6 months with prostatic RI measurements. RESULTS: According to the PFS the obstructive group included 158 patients and the unobstructive group 180 patients. The mean (SD) prostatic RI was significantly higher in the obstructive group, at 0.73 (0.04), than in the unobstructive group, 0.65 (0.05) (P < 0.001). Using the ROC curve a prostatic RI of ⩾ 0.71 predicted BOO secondary to BPH, with 84.6% sensitivity, 78.4% specificity and 83.8% overall predictability. After management, the prostatic RI of the obstructive group, 0.69 (0.08), was significantly lower than before treatment, 0.73 (0.04) (P < 0.05). CONCLUSIONS: The prostatic RI can predict BOO with high specificity and sensitivity. We believe that the prostatic RI could be a useful variable for the diagnosis and follow-up of patients with BPH.
RESUMO
OBJECTIVES: We report on the long-term functional results of the orthotopic Y-ileal neobladder and compare the outcome of the antireflux technique for ureteral implantation versus direct anastomosis. PATIENTS AND METHODS: Between 1990 and 2002, 120 patients underwent cystoprostatectomy and orthotopic Y-shaped ileal neobladder for invasive bladder carcinoma. The direct Nesbit technique for ureteral reimplantation was applied in 58 patients (group 1) and in 62 patients the ureters were reimplanted using the Le Duc antirefluxing technique (group 2). The mean follow-up period was 72 months (range, 36-144 months). RESULTS: Of 62 patients who underwent the Le Duc technique, six (9.7%) had unilateral uretero-ileal anastomotic stricture and four (6.5%) had reflux. Of 58 patients who underwent direct anastomosis, six (10.3%) patients had unilateral reflux, four of them had dilated ureters preoperatively and no patient had uretero-ileal anastomotic stricture. The incidence of stricture formation in the Le Duc technique is significantly higher than direct anastomosis (P = 0.04). There was no significant difference in the overall incidence of reflux in both groups. However, the incidence of reflux in preoperatively dilated ureters was significantly higher in direct ureteral anastomosis than Le Duc technique (40% in group 1 vs 16.7% in group 2; P = 0.045). The incidence of stone formation, azotemia, pyelonephritis and bacteriuria was comparable in both groups. The urodynamic findings showed a mean increase in the neobladder capacity at 6 and 18 months after surgery by 340 and 560 mL, respectively. The mean of the maximum pressure was 22 +/- 10 cm H2O, 18 months after surgery. Daytime and nighttime continence was good or satisfactory in 93.3% and 85.5% of the patients, respectively, after 3 years of follow-up. CONCLUSIONS: The functional and voiding results of a Y-shaped neobladder pouch using 40 cm of ileum are similar to the more sophisticated larger pouches. Direct uretero-ileal anastomosis in orthotopic bladder replacement is more reasonable than the Le Duc antireflux technique in non-dilated ureters. The benefit of the antireflux technique has been overestimated despite of the frequency of stricture formation.

AIM: We evaluated the possibility that patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) might have similar histological and physiological bladder changes as that documented in patients with painful bladder syndrome/interstitial cystitis (PBS/IC). METHODS: Thirty-five known patients of CP/CPPS according to the clinical criteria of National Institutes of Health (NIH) were evaluated. The severity of the symptoms was evaluated according the NIH-Chronic Prostatitis Symptom Index. All patients underwent a potassium sensitivity test (PST) and bladder cystoscopy. Bladder biopsy was obtained from 17 patients with prostatitis and four control patients. RESULTS: Urinary symptoms were present in 31 (88.6%) patients. Pelvic pain was reported in all patients. PST was positive in 26 (84%) of 31 patients that presented with urinary symptoms in its filling phase. In the voiding phase, 10 (28.5%) patients experienced urethral pain. Of these patients, five had negative filling PST. There were only two (5.7%) patients that had negative PST in both of its phases for an overall positive PST rate of 94.3%. The severity of PST was not correlated with the total symptom score (P = 0.37). However, patients with severe urinary symptoms were more likely to score higher grades with PST (P = 0.01). Of the 17 patients who underwent bladder biopsy, a significant increase in the number of mast cells (MC) was present in 11 (64.7%) patients. Glomerulations with bladder cystoscopy was observed in 24 (68.6%) patients. CONCLUSIONS: The data of the present study support the opinion that PBS/IC is under-diagnosed in male patients that present with urgency, frequency and/or pain. In some patients diagnosed as CP/CPPS, the symptoms might be related to bladder dysfunction rather than prostatic inflammation.
