AUGMENTATION URETEROCYSTOPLASTY COULD BE PERFORMED MORE FREQUENTLY

Abstract

Purpose: Megaureter represents the ideal tissue for bladder augmentation but to date ureterocystoplasty has been used only in select cases. We demonstrate that ureterocystoplasty can be used more frequently by dividing the megaureter and using its distal part for bladder augmentation and proximal part for reimplantation into the bladder. This technique can be performed as a 1 or 2-stage procedure.Materials and Methods: From November 1995 to October 1998 ureterocystoplasty was performed in 16 patients 3 to 12 years old (mean age 6.6). In 9 cases with impaired renal function loop cutaneous ureterostomy had been previously done to preserve and improve renal function. In the remaining 7 cases bladder augmentation and simultaneous ureteroneocystostomy were performed without cutaneous ureterostomy. Ureterocystoplasty was done extraperitoneally. This distal part of megaureter was used for bladder augmentation and the proximal part was implanted into the bladder using extravesical detrusor tunneling ureteroneocys...
