Primary Obstructive Megaureter in Children: to Treat or not?

Objective: Primary obstructive megaureter has always been considered a developmental defect. Surgical and conservative treatments were compared through a retrospective study first, and then in a longitudinal observational study. Materials and methods: Between January 1993 and January 2006 at our Department 42 cases of primitive obstructive megaureter were observed. Patients were divided into two groups: treated and untreated, each with inclusion and exclusion criteria. The efficacy of surgical treatment vs. conservative treatment was assessed through routine laboratory tests, ultrasound of the urinary tract and renal scintigraphy. Follow-up was at least 2 years for all patients.
