Abstract
OBJECTIVE: Surgical management for neurogenic bladder may require abandonment of the native urethra due to intractable urinary incontinence, irreparable urethral erosion, severe scarring from previous transurethral procedures, or urethrocutaneous fistula. In these patients, bladder neck closure (BNC) excludes the native urethra and provides continence while preserving the antireflux mechanism of the native ureters. This procedure is commonly combined with ileovesicostomy or continent catheterizable stoma, with or without augmentation enterocystoplasty. Alternatively, BNC can be paired with suprapubic catheter diversion. This strategy does not require a bowel segment, resulting in shorter operative times and less opportunity for bowel-related morbidity. The study purpose is to examine preoperative characteristics, indications, complications, and long-term maintenance of renal function of BNC patients. METHODS: A retrospective review of medical records of 35 patients who underwent BNC with suprapubic catheter placement from 1998 to 2007 by a single surgeon (LKL) was completed. RESULTS: Neurogenic bladder was attributable to spinal cord injury in 71%, 23% had multiple sclerosis, and 9% had cerebrovascular accident. Indications for BNC included severe urethral erosion in 80%, decubitus ulcer exacerbated by urinary incontinence in 34%, urethrocutaneous fistula in 11%, and other indications in 9%. The overall complication rate was 17%. All but two patients were continent at follow-up. Forty-nine per cent of patients had imaging available for review, none of which showed deterioration of the upper tracts. CONCLUSIONS: Our results suggest that BNC in conjunction with suprapubic catheter diversion provides an excellent chance at urethral continence with a reasonable complication rate.
