Abstract

One hundred and twenty-two augmentation cystoplasties performed over an 8-year period were reviewed. Mean age at surgery was 37 years (range 2–82 years). There were 82 female patients. The primary urodynamic diagnosis was reduced compliance in 92 (77%) pattenls and detrusor hyperreflexia/instability in the remainder. The clinical diagnostic groups were: spinal cord injury/disease in 32 (27%), myelodysplasia in 27 (22%), interstitial cystitis in 21 (17%), idiopathic detrusor instability in 13 (11%), radiation cystitis in 8 (7%). Hinman-Allen syndrome in 5 (4%), and miscellaneous in 11 (9%). A detubularized, ileal augmentation was used in 82 (67%) patients. In 36 (30%) a detubularized ileocecocystoplasty was fashioned and in the remainder detubularized sigmoid was used. In 19 patients augmentation accompanied undiversion. Sixteen patients had a simultaneous fascial sling for urethral incompetence. Mean follow-up was 37 months (range 6–96 months). There was no postoperative mortality. During follow-up 4 patients died from unrelated causes, 11 have been lost to follow-up, and 5 patients await planned transplantation. Bladder capacity was increased from a preoperative mean of 108 ml (range 15–500 ml) to 438 ml (200–1,200 ml) postoperatively. Of the 106 assessable patients, 80 (75%) had an excellent result, 21 (20%) were improved, and 5 (5%) had major ongoing problems.

During the period of follow-up, 17 (16%) patients underwent revision of their augmentation. Twenty-four (21%) patients developed bladder stones and 30% of these did so more than once. Urinary incontinence became manifest in 15 (13%) patients but required surgical treatment in only half of these. Pyelonephritis occurred in 13 (11%) patients. Five patients developed small bowel obstruction following discharge from hospital. There were 7 instances of reservoir rupture in 5 (4%) patients. Augmentation cystoplasty has a pivotal role in the treatment of a broad range of lower and upper urinary tract problems. Careful patient selection and close follow-up are essential. © 1995 Wiley-Liss, Inc.
