Congenital midureteral stricture is an uncommon cause of prenatal hydronephrosis, and it is generally associated with proximal hydroureteronephrosis . We report a unique case of a congenital severe midureteral dilatation associated with mild proximal ureteral dilatation and normal distal ureteral diameter. The dilated midureter was excised, and an open end-to-end ureteroureterostomy was performed. Follow-up 6 months after surgical correction revealed marked improvement in the left-sided hydronephrosis and complete resolution of the hydroureter.

Introduction: Most congenital ureteral strictures occur at the ureteropelvic or ureterovesical junction in children. Mid-ureteral stricture is very rare and can cause congenital hydronephrosis. Only a few studies have reported on coexisting mid-ureteral stricture with ipsilateral atrophic kidney in young adults.

Purpose: To compare the safety and outcomes of open and laparoscopic procedures in the management of congenital midureteral obstruction in children (CMO).
Methods: Between February 2008 and February 2022, a total of 18 patients underwent open ureteroureterostomy (OU group), and 26 underwent laparoscopic ureteroureterostomy (LU group). The operative time, postoperative hospital stay, hospital costs, postoperative complications, and success rates of the two groups were compared.

Background: Midureteral stenosis is very rare in children and can cause congenital hydronephrosis. We report our experience treating children with congenital midureteral stenosis at our center, focusing on the differences in preoperative diagnosis and treatment compared with other congenital obstructive uropathies.
Methods: We retrospectively reviewed the medical records of 26 children diagnosed with congenital midureteral stenosis at our center between January 2007 and December 2020, such as preoperative examination methods, intraoperative conditions, and postoperative follow-up results.

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).
