Detrusorrhaphy: extravesical ureteral advancement to correct vesicoureteral reflux in children.

We used a modified extravesical technique, coined detrusorrhaphy, to correct surgically vesicoureteral reflux. By detrusorrhaphy the submucosal ureteral tunnel is opened, the ureteral meatus is advanced and anchored onto the trigone, and the detrusor buttress of the ureter is closed (-rrhaphy). The operation is performed extravesically. The procedure was used in the last 5 years in 79 children, or 120 renal units. Reflux resolved in 93 per cent of the renal units. Postoperative morbidity related to bladder spasms and hematuria was minimal compared to conventional transvesical surgical procedures. Detrusorrhaphy is an effective method to correct vesicoureteral reflux and to minimize postoperative morbidity.
