Abstract：Objective: We present our experience with using rigid nephroscopy for renal calculi removal during robot-assisted pyeloplasy (RAP) for UPJO. Methods: 17 patients who underwent RAP for UPJO and rigid nephroscopy for renal calculi were enrolled in our study. Their medical records were analysised retrospectively. Results: UPJO were found on dual sides, the left side and the right side in 1, 6 and 7 patients respectively. The average operative time was 180.5 min, which was 40.9 minutes longer than the mean operative time in patients without renal calculi. There was no significant difference in blood loss, hospital stay, complications, and success rates between patients with and without renal calculi. Conclusions: The use of a concomitant rigid nephroscope and RAP is a safe and feasible option for the treatment of UPJO complicated with renal calculi.
