Multi‐institutional studies are extremely valuable whena new surgical technique is being introduced. The Confederationof American Urology conducted such a study into the functional results inmales and females of the orthotopic bladder. In a series of 138patients they found many interesting outcomes, which they presenthere. Authors from Sheffield describe their experience in developing tissue‐engineeredbuccal mucosa for use in urethral reconstruction. They describetheir technique and report the successful culture of full‐thicknessbuccal mucosa, which they found to be robust and safe for clinicaluse. OBJECTIVES To analyse the incidence of diurnal incontinence (DI) and nocturnalincontinence (NI), the need for intermittent catheterization (IC),and the rate of ureteric obstruction (UO) among a group of men andwomen with ileal and colonic orthotopic neobladders in four countries. PATIENTS AND METHODS In all, 138 patients (113 men and 25 women) had an orthotopicneobladder constructed after radical cystectomy for carcinoma. The mean(range) age was 61.3 (28–76) years and thefollow‐up 41 (6–144) months. All patients underwentsurgery by experienced surgeons associated with the Confederationof American Urology. A retrospective evaluation was designed toreview the functional results and the incidence of UO. The techniqueof orthotopic neobladder construction was at each surgeon's discretion. Various detubularized bowelsegments were used, including ileum, colon or sigmoid. Patients werefollowed by chart reviews and personal interviews at 1, 3 and 6 monthsafter surgery and then every 6 months, and were evaluated bya physical examination, urine analysis, cytology and renal ultrasonography. RESULTS An ileal or colonic neobladder was constructed in 74 and 64 patients, respectively.Five (7%), 23 (31%), 10 (14%) and 14(9.6%) with an ileal neobladder developed DI, NI, IC andUO, respectively; the respective values for patients with a colonicneobladder were eight (12%), 19 (30%), seven (11%)and 15 (12%). Statistical analysis by Fisher’sexact test showed no significant differences between the ileal andcolonic neobladder groups or with gender. CONCLUSIONS Using this specific protocol for evaluating many men and womenwith ileal and colonic orthotopic neobladders showed no significant differencesin the incidence of DI, NI, IC or UO. Neobladders constructed fromdetubularized bowel, irrespective of bowel segment(s) used, canprovide satisfactory diurnal results. A moderate incidence of NIand UO continue to be a problem.
