Functional lower urinary tract voiding outcomes after cystectomy and orthotopic neobladder

Purpose: We reviewed our experience with orthotopic continent urinary reconstruction after radical cystectomy to determine the functional voiding patterns and compare different methods of reservoir construction. Materials and Methods: The study included 100 consecutive patients who underwent cystectomy and orthotopic neobladder. Reservoir construction consisted of a W-shaped ileal reservoir in 40 patients, ileal reservoir with afferent limb in 26, a Padua ileal reservoir in 18, right colon in 14 and sigmoid colon in 2. The functional voiding outcome was determined by a detailed patient interview and chart review. Results: There were no perioperative deaths. All patients regained good daytime urinary control and none required protective pads, although 18% used protective padding at night because of nocturnal leakage. Eight patients (8%) performed self-intermittent catheterization because of poor reservoir emptying. There were no substantial differences in outcomes among the various methods of reservoir construction. Conclusions: Excellent functional voiding outcomes are obtained with radical cystectomy and orthotopic bladder reconstruction. Comparable results can be achieved with use of either large bowel or ileum and with various methods of bowel folding as long as principles of preservation of the periurethral sphincter muscle, and construction of an adequate capacity and low pressure reservoir are maintained.
