Abstract

Objective: To report a 6-year multi-institutional experience and outcomes with robot-assisted laparoscopic pyeloplasty (RLP) for the repair of ureteropelvic junction obstruction (UPJO). Patients and Methods: Between June 2002 and October 2008, 168 adult patients from 3 institutions underwent RLP for UPJO. A retrospective analysis of prospectively collected data were performed after institutional review board approval. Diagnosis was by intravenous urogram or computed tomography scan and diuretic renogram. All patients underwent RLP through a 4-port laparoscopic technique. Demographic, preoperative, operative, and postoperative endpoints for primary and secondary repair of UPJO were measured. Success was defined as a T of <20 minutes on diuretic renogram and symptom resolution. Pain resolution was assessed by subjective patient reports. Results: Of 168 patients, 147 (87.5%) had primary repairs and 21 (12.5%) had secondary repairs. Of the secondary repairs, 57% had a crossing vessel etiology. Mean operative time was 134.9 minutes, estimated blood loss was 49 mL, and length of stay was 1.5 days. Mean follow-up was 39 months. Overall, 97.6% of patients had a successful outcome, with a 6.6% overall complication rate. Conclusions: To our knowledge, this review represents the largest multi-institutional experience of RLP with intermediate-term follow-up. RLP is a safe, efficacious, and viable option for either primary or secondary repair of UPJO with reproducible outcomes, a high success rate, and a low incidence of complications.
