Coexisting congenital mid-ureteral stricture and megaureter due to ureterovesical junction obstruction: A case report

Congenital mid-ureteral strictures (CMS) are rare. Most congenital strictures occur at the ureteropelvic junction or ureterovesical junction, with mid-ureteral strictures accounting for only 4–5% of all cases of ureteral obstruction in children. Furthermore, there are very few reports of coexisting...

Sumario:Congenital mid-ureteral strictures (CMS) are rare. Most congenital strictures occur at the ureteropelvic junction or ureterovesical junction, with mid-ureteral strictures accounting for only 4–5% of all cases of ureteral obstruction in children. Furthermore, there are very few reports of coexisting mid-ureteral stricture and ureterovesical junction obstruction (UVJO). Here, we report a case of coexisting UVJO and CMS. CMS was not detected on preoperative magnetic resonance imaging, and hydronephrosis remained after ureteroneocystostomy. Therefore, MRI was repeated and CMS was diagnosed, for which we performed ureteroureterostomy. Intraoperative retrograde pyelography (RGP) aids definitive diagnosis of UVJO.
