Ureteroceles in children. A simplified and successful approach to management.

This review documents the success that we have experienced in treating most ureteroceles that present in children by heminephroureterectomy. If excision of the ureterocele is required, or reimplantation of a ureter other than the ureter obstructed by the ureterocele, this is deferred until the degree of hydronephrosis is reduced or bladder thickening and trabeculation have returned toward normal. In instances where there is function in the upper pole segment obstructed by the ureterocele, ureteropyelostomy has enabled us to preserve renal function by removing the obstructed ureter to permit the ureterocele to collapse.
