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

Abstract

We describe our experience with reconstruction of the ureter in 2 patients who sustained extensive upper and mid ureteral loss as newborns. 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. Both patients had a successful outcome with no evidence of anastomotic stenosis or obstruction. 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.
