OBJECTIVES: To evaluate our current practice in retroperitoneoscopic pyeloplasty in patients with ureteropelvic junction obstruction (UPJO). Special interest was paid to technical difficulties associated with the retroperitoneoscopic approach. METHODS: Our retroperitoneoscopic approach for pyeloplasty is explained step for step including the most technically challenging part: the ureteropelvic anastomosis. RESULTS: Within 49 months a total of 47 retroperitoneoscopic pyeloplasties we performed at our institution. Before pyeloplasty an endopyelotomy had failed in five patients (11%). We did not necessarily perform a ventral transposition of the anastomosis in cases with a crossing vessel. Two (4%) conversions to open surgery were required because of scarring after previous endopyelotomy and massive obesity resulting in a limited working space. There were no intraoperative complications. A recurrence of UPJO was observed in 2% (n = 1). CONCLUSION: Functional results after retroperitoneoscopic pyeloplasty are excellent and comparable to those of open surgery. However, special knowledge of retroperitoneoscopy is necessary to provide the patient with a safe and effective minimally invasive alternative to open pyeloplasty.
