Congenital mid-ureteral stricture: a case report of two patients

Background Congenital hydronephrosis is a common foetal anomaly. There are numerous causes of hydronephrosis. The diagnosis of ureteral anomalies remains challenging. Congenital mid-ureteral stricture (CMS) is less common than proximal and distal strictures. In most cases involving CMS, this condition is diagnosed intra-operatively. The gold standard treatment is resection of the stenosed segment and ureteroureterostomy.
