Extensive upper and mid ureteral loss in newborns: experience with reconstruction in 2 patients.

Purpose: We describe our experience with reconstruction of the ureter in 2 patients who sustained extensive upper and mid ureteral loss as newborns.

Materials And Methods: Two male patients, a 1-month-old and a neonate, sustained extensive ureteral loss due to candidal infection involving the retroperitoneum and ureter. The 1-month-old sustained a loss of the middle third of the ureter, and the neonate sustained a 3 cm. loss of the upper ureter. The first case was managed with a combination of renal mobilization and an extensive Boari flap, while the second was managed with renal mobilization and nephropexy with primary ureteropyelostomy.

Results: Both patients had a successful outcome with no evidence of anastomotic stenosis or obstruction.

Conclusions: Extensive upper and middle third ureteral defects may be primarily bridged successfully in pediatric patients using the standard technique of renal mobilization combined with ureteropyelostomy and a Boari flap, respectively.
