Ipsilateral ureteroureterostomy in the management of duplicated collecting system and ureterocele.

Ureteroceles are commonly associated with duplicated collecting systems and most often involve the ureteral orifice draining the upper pole. Obstruction, infection and parenchymal damage may result in such circumstances. Operative intervention is indicated for the preservation of renal parenchyma and the maintenance of renal function. While numerous surgical options are available in managing such situations, ureteroureterostomy is an excellent choice as it (1) avoids ureteral reimplantation and trigonal reconstruction; (2) does not require a technically difficult anastomosis; (3) avoids injury to the ipsilateral normal ureter and (4) does not risk renal injury.
