Abstract

Purpose: Endopyelotomy has gained acceptance as minimally invasive therapy for ureteropelvic junction obstruction in adults. Its role in the treatment of pediatric ureteropelvic junction obstruction remains controversial. We report our experience with antegrade endopyelotomy for treating pediatric ureteropelvic junction obstruction. Materials and Methods: A total of 17 patients 3 months to 17 years old underwent endopyelotomy as primary treatment for ureteropelvic junction obstruction (8) and after failed open pyeloplasty with secondary endopyelotomy performed a mean of 12 weeks after open pyeloplasty (9). Standard antegrade percutaneous techniques were used. Electrosurgical incision of the ureteropelvic junction at a posterolateral orientation was done in each case. Internal ureteral stents remained in place for 4 to 6 weeks postoperatively. Results: In 5 of the 8 patients (62%) treated primarily the outcome was successful at a mean followup of 38 months (range 25 to 53). Failures occurred at 6 weeks, 3 months and 5 months. In all 9 patients treated secondarily outcomes were successful at a mean followup of 59 months (range 16 to 110). Conclusions: Endopyelotomy as primary treatment of pediatric ureteropelvic junction obstruction remains controversial but it may be appropriate in select cases. On the other hand, endopyelotomy is safe and effective for pediatric patients in whom open pyeloplasty fails.
