OBJECTIVES: To assess the results of secondary endopyelotomies (SEP) that were performed in our center in children who had earlier failed pyeloplasty. METHODS: Eleven secondary endopyelotomies were done between 2005 and 2010 in 10 patients (5 boys and 5 girls, mean age 6.8 years), with a follow-up time of >6 months. The primary procedure was an open/laparoscopic pyeloplasty (n = 10) or a ureterocalicostomy (n = 1). In all cases, endopyelotomy was done by means of a monopolar electrocautery hook using the standard pediatric resectoscope. In 10 patients, SEP was done percutaneously, and in 1 patient it was done in a retrograde fashion. The mean operation time was 69 minutes. RESULTS: After a mean follow-up of 20 months, 70% of patients were free of complaints (n = 7), which was defined as a resolution of complaints, resolution of hydronephrosis, and improvement of renal wash-out curve and function. In 4 renal units, reintervention had to be considered; in one of these, a re-pyeloplasty has already been performed. The mean postoperative hospital stay was 2.8 days. No intraoperative complications occurred. In 1 patient, postoperative leakage around the nephrostomy drain occurred but resolved spontaneously. CONCLUSIONS: SEP is a fairly safe method to treat recurrent ureteropelvic junction-stenosis after failed pyeloplasty in children. However, because it seems to be less affective than the open redo pyeloplasty, it cannot be considered as a gold standard procedure and as such should be thoroughly discussed with the patient and parents.
