Abstract

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.

Case presentation

We report two patients with CMS which presented as antenatal hydronephrosis with postnatal workup showed a picture of pelviuretric junction obstruction which required surgical correction. Intraoperative retrograde pyelography (RGP) confirmed the diagnosis of mid ureteral stricture which make us to change the planned surgical intervention from pyeloplasty to excision of the ureteral stricture and ureteroureterostomy as definitive management.

Conclusion

CMS should be considered whenever proximal mega-ureter is an associated finding. Despite advanced radiological modalities, RGP remains the mainstay approach for diagnosing ureteral anomalies.
