Objective: To evaluate the efficacy and safety of a single intra detrusor injection of BoNTA comparing two different doses (100 U or 200 U) in patients with idiopathic overactive bladder. Materials and Methods: A randomized prospective study evaluated the efficacy of BoNTA in management of refractory idiopathic overactive bladder and included 80 patients. All patients were assessed initially by taking a history, a physical examination, overactive bladder symptom score, urine analysis, routine laboratory investigations, KUB and pelviabdominal. OABSS was adjusted on all patients postoperative at 1,3,6,9 months also Urodynamic was done for all patients preoperative and postoperative at 3, 6, 9 months. Results: The mean age was 30.22±8.37 and 31.35±7.61 in group I and II respectively. There was no statistically difference between both groups in all parameters all over the study except at 9 months after treatment. Hematuria was observed 6 and 9 patients in group I and II respectively. Dysuria was observed in 6 and 15 patients in group I and II respectively. UTI was detected in 3 and 7 patients in group I and II respectively. Conclusion: A single-injection procedure of 100 U or 200 U BoNTA is an effective and safe treatment for patients with IOAB who failed anticholinergic regimens. OABSS and QoL were improved for 6 months; 100 U injections seemed to have comparable results with 200 U. There was a significant difference at month 9 towards 200 U with more incidences of adverse events.

PURPOSE: Analyze current knowledge and practice regarding tumor-related cystectomy with subsequent orthotopic neobladder both in male and female patients. DESIGN, SETTING, AND PARTICIPANTS: Evaluate literature predominantly from the last decade dealing with long-term experience in large numbers of patients with an orthotopic neobladder following cystectomy. Oncological outcome specific to an orthotopic neobladder, functional aspects such as urinary continence, renal function, sexual activity and other quality of life issues are elucidated. RESULTS: Local pelvic recurrences after urothelial bladder cancer occur in 7-12%. Urethral second primary tumors in male and female patients in contemporary series with bladder substitution are 4-6% and 1.4 o 4%, respectively. Upper tract recurrences vary between 2.4-17%. Complications regarding the upper urinary tract have dramatically diminished due to simplified forms of upper tract protection as well as a more refined technique of ureterointestinal anastomosis. Depending on the technique ureteroileal stenosis was lately reported to lie between 2.7 to 3.8%. Renal function remained stable in 96% after a mean follow-up of up to 5 years. Radical cystectomy in carefully selected patients has stood the test of time by providing adequate long-term survival and low local recurrence rates. Orthotopic bladder substitution does not compromise oncological outcome, yields excellent functional results, is cost effective compared to other types of urinary diversion, may improve quality of life and should therefore be the diversion of choice both in men and women. Chronological age is generally not a contraindication for cystectomy, but for orthotopic urinary diversion, tumor extent, functional pelvic floor deficits and general life expectancy are limiting factors.
