title: [Recent outcome of bladder augmentation using deepithelialiezed segment of small intestine lined with urothelium].
abstract: OBJECTIVE
  To evaluate urodynamically and clinically bladder augmentation using double-deepithelialized segment of the small intestine lined with urothelium to analyse the recent outcome to treatment of hyperreflexia neurogenical bladder.
  
  
  METHODS
  25 patients with neurogenical bladder underwent bladder augmentation using deepithelialized segment of the small intestine lined with urothelium (4 - 14 years old, 16 males and 9 females) from October 1998 to October 2000. 21 patients were followed up. Voiding cystoureterography and urodynamic and clinical evaluation were performed, and serum electrolyte, urea nitrogen and creatinine were tested before and 6 months to 2 years after operation.
  
  
  RESULTS
  After operation, bladder volume, maximum urine flow rate and compliance were increased, but residual urine/bladder volume and detrusor pressure decreased. Uninhibitory contraction decreased in 15 patients. In 12 patients associated vesicoureteral reflux, clinical evaluation revealed poor outcomes before operation, but excellent (4 patients), good (9), effective (4), poor outcomes (4) after operation. Seven patients had urinary sensation recovered. Vesicoureteral reflux decreased in 9 patients. There were no electrolyte unbalance and abnormal renal function in all patients.
  
  
  CONCLUSIONS
  Bladder augmentation using double-deepithelialized segment of the small intestine lined with urothelium shows a better result currently.
