A surgical fix for kids with duplex kidney anomalies is proving highly effective. A retrospective study of 53 children found that distal ureteroureterostomy resolved or improved upper moiety hydronephrosis in nearly 88% of cases, with zero reoperations over a median 45-month follow-up. The procedure also had a low complication rate, making it a reliable option for young patients with this complex condition.
A kidney-preserving surgery called distal ureteroureterostomy is delivering impressive outcomes for children born with duplex kidney anomalies — a condition where the kidney has two separate collecting systems instead of one. A retrospective study of 53 children (mostly girls, median age 15 months) found that the procedure effectively addressed the main surgical indications, including recurrent febrile urinary tract infections, progressive upper tract dilatation, and urinary incontinence.
Over a median follow-up of 45 months, not a single patient required reoperation, and no clinically relevant obstruction of the lower kidney portion was observed. Upper moiety hydronephrosis improved significantly in 88.4% of patients, with a median reduction in pelvic diameter of 11 mm.
By the Numbers:
Why it matters: Duplex kidney anomalies are among the more complex pediatric urological conditions, and finding a safe, definitive surgical approach is critical. These findings support distal ureteroureterostomy as a reliable reconstructive option — sparing the kidney while delivering durable, complication-free results for young patients.
