title: Detrusorectomy for neuropathic bladder in patients with spinal dysraphism.
abstract: OBJECTIVE
  We assess the outcome of detrusorectomy in 35 patients with spina bifida who were incontinent due to poor bladder volume or poor compliance.
  
  
  METHODS
  Of 51 patients requiring bladder augmentation 35 underwent detrusorectomy. In 3 patients ileocystoplasty was later performed as a secondary procedure because of failure of the detrusorectomy.
  
  
  RESULTS
  A total of 35 patients (17 males, 18 females) underwent detrusorectomy. Mean patient age at operation was 9.9 years (range 0.4 to 17.8). Mean followup was 4.9 years (range 1 to 10.5). A continent catheterizable vesicostomy was constructed in 14 patients and ureteral reimplantation was performed in 8. Twenty-five patients also underwent sling and/or Burch cystourethropexy during detrusorectomy, of whom 19 are continent and 5 have some leakage between clean intermittent catheterizations. In 1 girl the sling procedure was not successful, and she was subsequently treated with bladder neck closure. Bladder compliance after operation was improved in 9 cases and unchanged in 10. Of the 16 patients in whom compliance was already acceptable before the operation and was unchanged after detrusorectomy 7 were able to stop antimuscarinic therapy. Compliance became poor in 4 cases, of which 3 required ileocystoplasty. Bladder volume (as a percentage of normal volume for age) was increased after detrusorectomy in 13 patients, unchanged in 11 and decreased in 11. Complications of detrusorectomy included bladder leakage in 2 cases. One patient needed a laparotomy because of urinary ascites shortly after the operation.
  
  
  CONCLUSIONS
  Detrusorectomy may be combined with other procedures such as ureteral reimplantation, slingplasty and continent vesicostomy. Of 35 treated patients compliance improved in 16 (46%),volume improved in 13 (37%), 3 had no change in parameters, and 3 had a slight decrease in volume and compliance. Four patients had poor results, of whom 3 needed a secondary ileocystoplasty. Therefore, it may be concluded that detrusorectomy is a safe and probably useful procedure for improvement of bladder volume and compliance in patients with neurogenic bladder dysfunction, and may obviate the need for ileocystoplasty in a limited number of patients.
