OBJECTIVE We assessed the efficacy and safety of percutaneous endopyelotomy in infants and young children with secondary ureteropelvic junction obstruction after previous open pyeloplasty. METHODS Three boys and 2 girls with persistent ureteropelvic junction obstruction after open pyeloplasty underwent percutaneous antegrade cold knife endopyelotomy via an 18F nephrostomy tract. RESULTS Percutaneous endopyelotomy was successfully performed in all 5 children with minimal complications. At a mean followup of 2.5 years endopyelotomy was successful in 4 of the 5 children based on the absence of symptoms, normal pressure-perfusion studies and normal or improved diuretic renal scintigraphy studies. One child in whom endopyelotomy failed underwent successful ureterocalicostomy. CONCLUSIONS Percutaneous antegrade endopyelotomy is a safe and efficacious method of treating secondary ureteropelvic junction obstruction in children. This method offers a minimally invasive alternative to conventional repeat open pyeloplasty.
