Is concomitant bladder neck reconstruction necessary in neurogenic incontinent patients who undergo augmentation cystoplasty?

PURPOSE: In patients with neurogenic bladder due to spinal cord injury or disease who undergo augmentation cystoplasty (AC) for not only bladder dysfunction but also sphincteric incontinence, the need for concomitant bladder neck reconstruction at the time of AC has not yet been established. The aim of this study was to evaluate whether concomitant bladder neck reconstruction is necessary when performing AC. MATERIALS AND METHODS: We retrospectively investigated 35 patients who underwent AC from January 2006 to September 2010. Medical history, preoperative and postoperative fluoroscopic urodynamic study (FUDS) parameters, and responses to an incontinence questionnaire (ICIQ Korean version) were reviewed. RESULTS: A final analysis was performed on 17 patients (9 male, 8 female) who were diagnosed with sphincteric incontinence. Continence status, the number of pads used, and the bother score were significantly improved postoperatively in this subpopulation. Preoperatively, all patients used pads, and the average daily number was 2.2 (median; range 0 to 6). Postoperatively, the number of pads used decreased significantly to 0.9 (median; range 0 to 3) pads a day (p=0.002). Urodynamic parameters including bladder capacity, compliance, involuntary detrusor contraction, and bladder neck incompetence proven by FUDS were also significantly improved. CONCLUSIONS: Our study demonstrated that both objective urodynamic parameters and subjective incontinence symptoms improved significantly after the completion of AC as a single procedure in patients with sphincteric incompetence. This implies that anti-incontinence bladder outlet surgery does not have to be performed simultaneously and can be considered later as a staged operation.
