    Author: Quek ML, Ginsberg DA.
    Journal: J Urol; 2003 Jan; 169(1):195-8. PubMed ID: 12478134.
    Abstract:
    PURPOSE: Augmentation enterocystoplasty is well tolerated by patients with neurogenic bladder in whom conservative therapy has failed. However, few studies exist on long-term urodynamic evaluation of these patients. We assessed the clinical and urodynamic outcomes of patients with neurogenic bladder treated with augmentation enterocystoplasty with at least 4 years of followup. MATERIALS AND METHODS: A total of 26 patients with neurogenic voiding dysfunction underwent augmentation enterocystoplasty alone or in conjunction with various continence or antireflux techniques. Clinical outcomes regarding incontinence, medications, catheterization schedule, subsequent interventions, bowel function and patient satisfaction were addressed. Urodynamic evaluation was performed to assess the long-term durability of bladder augmentation. RESULTS: Mean followup was 8.0 years (range 4 to 13). All but 1 patient (96%) in our series had near or complete resolution of urinary incontinence. Mean total bladder capacity +/- SD increased from 201 +/- 106 to 615 +/- 204 ml. (p <0.001) and mean maximum detrusor pressure decreased from 81 +/- 43 to 20 +/- 12 cm. H O (p <0.01). Mean interval between catheterizations was 5 hours, with volumes ranging from 314 to 743 ml. Only 2 patients (8%) needed a low dose of oxybutynin postoperatively to maintain continence consistently. Of the 26 patients 23 (88%) reported no significant change in bowel function and nearly all patients expressed extreme satisfaction with urological management. A subsequent urological procedure was required in 12 patients (46%) at a mean of 4.4 years after initial surgery.(2) CONCLUSIONS: Bladder augmentation provides durable clinical and urodynamic improvement for patients with neurogenic bladder dysfunction refractory to conservative therapy. Furthermore, there is a high level of patient satisfaction with bladder augmentation.
