Ureteral reimplantation en bloc for refluxing duplicated ureters

Vesicoureteric reflux (VUR) is a major problem in completely duplicated ureters. So far, the treatment of choice has been the reimplantation of the two ureters in their common sheath, the ureterocystoneostomy en bloc according to Politano-Leadbetter's or Cohen's procedure. In recent years, some pediatric surgeons and urologists have questioned the efficacy of this method. We therefore analyzed 62 children with 69 duplicated ureters treated en bloc by Politano-Leadbetter's procedure during the 20-year period 1971 – 1990. Postoperative follow-up was up to 16 years. We noted only 1 recurrence of reflux as well as 2 stenoses. Long-term results as far as function was concerned were also favorable in 40 duplicated renal units. Thus, ureteral reimplantation en bloc remains a simple and safe procedure for treating VUR in completely duplicated ureters.
