Long-Term Outcomes of Two Ipsilateral vs Single Double-J Stent After Laser Endoureterotomy for Bilharzial Ureteral Strictures.

Background: Laser endoureterotomy became a preferable choice for managing benign ureteral strictures. Ureteral stricture caused by bilharzias is characterized by focal destruction of ureteral musculature, ending by fibrosis, making it poor responder to endoureterotomy. There is no consensus about the ideal ureteral stent size after endoureterotomy. However, many researches recommend larger stents caliber (12-14F). We assess long-term efficacy of insertion of two ipsilateral Double-J stents vs single Double-J stent after laser endoureterotomy for bilharzial ureteral stricture. Materials and Methods: Within 4 years, 70 patients underwent retrograde laser endoureterotomy for bilharzial ureteral stricture (diagnosed by positive history of bilharziasis, positive serology test, and/or bilharzial cystoscopic finding). Patients with history of stone, urologic or pelvic surgery were excluded. Patients were randomized into two groups: the first group (35 patients) received ipsilateral two Double-J (7F each) postendoureterotomy, whereas the second group (35 patients) received one Double-J (7F). Double-Js were removed after 8 weeks. Follow-up was done regularly by clinical interpretation and imaging studies. Patients' characteristics, operative data, and postoperative outcomes (subjectively and objectively) were compared in both groups. Results: Sixty-three patients completed follow-up >18 months, mean follow-up 30 ± 4 months [19-41], and mean stricture length 1.4 ± 0.6 cm [0.5-3.0], with no statistical significance between both groups. Success proved by relief of symptoms and radiographic resolution of obstruction. The overall success rate was significantly better in 2-Double-J group than in 1-Double-J group (83.9% vs 53.1%) p = 0.009, and also for stricture >1.5 cm (85.7% vs 38.5%) p = 0.018, respectively. Conclusions: Insertion of two ipsilateral Double-J, after laser endoureterotomy for bilharzial ureteral stricture associated with long-term success rate better than insertion of 1-Double-J, especially for stricture segment >1.5 cm.

Outcome of orthotopic sigmoid versus ileal neobladder reconstruction.

INTRODUCTION: Radical cystectomy with orthotopic urinary diversion is considered the gold standard for treatment of muscular invasive bladder cancer or high-risk nonmuscular invasive bladder cancer. The choice of orthotopic neobladder reconstruction depends on the clinical outcomes of it and should be planned with the patients, especially the risk of incontinence. METHODS: this study included 52 Egyptian patients underwent radical cystectomy and orthotopic neobladder reconstruction with sigmoid (25 patients) and ileal (27 patients) segments. Postoperative clinical outcomes between the sigmoid and ileal neobladder groups were compared. RESULTS: In the present study, 12 intraoperative complications (6 in each group) and 19 postoperative complications (17 in sigmoid and 15 in ileal group) occurred; however, there was no significant difference in the incidence of intraoperative and postoperative complications between both groups. There were no significant differences in the continence status and spontaneous voiding between both groups. There were no significant differences in maximal flow rate and voided volume between both groups. Night voiding frequency in the ileal neobladder patients was significantly smaller than sigmoid neobladder patients. Free flowery showed a significant difference of voiding time and volume in favor of sigmoid neobladder group. Maximum urethral pressure and urethral closing pressure were significantly higher in ileal neobladder group. CONCLUSIONS: Both types of neobladder reconstruction resulted in comparatively satisfactory outcomes; however, the voiding function in sigmoid neobladder group appeared to be more favorable than that in ileal neobladder group.

Semi-Rigid Ureteroscopy for Proximal Ureteral Stones: Does Adjunctive Tamsulosin Therapy Increase the Chance of Success?

OBJECTIVES: To assess the efficacy of adjunctive tamsulosin therapy in improving the success rate of laser-assisted semi-rigid ureteroscopy (URS) for removing proximal ureteral stones. PATIENTS AND METHODS: This prospective study included 165 patients with proximal ureteral stones ≥10 mm. The patients were randomly assigned to a tamsulosin group (Group I, n = 81) receiving tamsulosin 0.4 mg daily for 1 week pre-URS and a control group (Group II, n = 84) without tamsulosin therapy. Treatment consisted of URS using a semi-rigid ureteroscope (7.5 Fr), followed by intracorporeal holmium: YAG laser lithotripsy. The patients were followed up regularly for 8 weeks after URS. RESULTS: The operative time was 43.4 and 49.6 min in Groups I and II, respectively (p < 0.001). Scope to stone access rate was 93.8 and 82.1% in patients of Groups I and II, respectively (p = 0.022). The stone-free rate was significantly higher in Group I compared to Group II (74/81; 91.4% vs. 67/84; 79.8%; p = 0.035). The complication rate was significantly lower in Group I compared to Group II (17.3 vs. 38.1%, p = 0.003). Only minor complications were encountered and were managed conservatively. CONCLUSIONS: Tamsulosin therapy prior to semi-rigid URS improved ureteroscopic access to proximal ureteral stones, thus leading to an increased success rate and low morbidity.
