Purpose: Data regarding the treatment of ureteropelvic junction obstruction (UPJO) in horseshoe kidneys are limited. We performed a retrospective analysis of our experience with minimally invasive treatment of UPJO in patients with this anomaly. Methods: Between March of 1996 and March 2008, 9 patients with horseshoe kidneys were treated for UPJO at our institution. Of these patients, 6 were managed with retrograde endopyelotomy, 2 with laparoscopic pyeloplasty, and one by robotic pyeloplasty. Outcomes of these procedures were retrospectively reviewed. Results: A total of nine patients were available for analysis. Four of six patients who underwent endopyelotomy had available follow-up, with a mean of 56 months. The success rate for these patients was 75%. Two of three patients (67%) in the laparoscopic/robotic cohort were successfully treated with a mean follow-up of 21 months. Conclusions: UPJO in horseshoe kidneys can pose a therapeutic dilemma. The minimally invasive treatment of these patients is feasible with good success rates for both endopyelotomy and laparoscopic/robotic pyeloplasty.
