The expanded role of transureteroureterostomy in pediatric urology

Transureteroureterostomy was used in 31 patients as a component in urinary undiversions, salvage procedures for failed reimplants/reconstructions and diversions with a sigmoid antirefluxing conduit or end cutaneous ureterostomy, as well as an adjunct to reimplantation procedures complicated by an abnormal bladder that precluded reimplantation of more than 1 ureter. Reconstruction in 29 patients involved procedures that changed the drainage of the recipient ureters for various reasons, including obstruction, reflux, undiversion and diversion. A neurogenic bladder was present in 26 patients and an additional 4 patients had a significant bladder pathological condition. Both ureters were dilated in 17 patients, while 1 was dilated in another 6. This series illustrates the versatility and confirms the success of transureteroureterostomy in high risk, complicated reconstructive urological procedures in children.
