Robotic-assisted laparoscopic pyeloplasty with the use of the Contour™ stent: description of the technique and analysis of outcomes after the first 30 cases.

INTRODUCTION: We present a technical variation of robot-assisted pyeloplasty (RAP) using the Contour™ stent that allows a minimal incision of the retroperitoneum. MATERIAL AND METHODS: The main difference from the standard robot-assisted pyeloplasty (RAP) is the preventive retrograde insertion of a Contour™ stent, which is a single J stent subsequently easily convertible in a double J stent. RESULTS: The mean operative time was 141.2 minutes. Blood losses were negligible, median length of stay was 4 days. CONCLUSIONS: The use of a Contour™ stent showed to be a safe and feasible technical variation while performing a RAP.
