Congenital hydronephrosis in the lower segment of a duplex system

Case Report


Two cases of hydronephrosis of the lower moiety in duplicated collecting systems, one associated with a complete duplication and another with an incomplete duplex system, are reported. This is a rare anomaly that requires a precise preoperative anatomic diagnosis to allow the planning of the most suitable surgical procedure. Treatment of this entity should follow similar guidelines as single-system hydronephrosis. An end-to-side dismembered pyeloureterostomy is the optimal operative technique.
