Brief Summary:

Prospective multicenter observational study of early infancy ureteral reimplantation for distal ureteral obstruction.

The study is an observation study since the investigators will not assign specific interventions to the subjects of the study.

The purpose of the study is to describe the surgical outcomes of early infancy ureteral reimplantation. Infants under 6 months of age with unilateral obstructed distal ureter, no other urologic pathologic and a normal contralateral kidney who have been recommended a ureteral reimplant by their pediatric urologist are eligible for the study. Patients that consent for the study will be prospectively followed for 1 year to record the outcomes of the surgery.
