Abstract：Objective: To explore the new technique of robot assisted pyeloplasty(RAP) for patients with ureteropelvic junction obstruction(UPJO) and to evaluate its clinical eficacy. Methods: 32 patients who underwent RAP for UPJO were enrolled in our study. Their medical records were analysed retrospectively. Results: UPJO was found on the left side in 24 patients and on the right side in 8 patients. The average operative time, blood loss and hospital stay were 158.6 (90-380) min, 47.8 (20-120) ml and 5.7 (3-15) days respectively. The mean follow-up of 10.5 (1-30) months by ECT and/or diuretic renogram confirmed the absence of obstruction in all patients, which resulted in a success rate, measured as an improvement in drainage, of 100%. Conclusions: Our data suggest that the RAP is a safe and feasible option for the treatment of UPJO.
