Introduction: Laparoscopic pyeloplasty (LP) is the first-line option for management of ureteropelvic junction obstruction (UPJO).1,2 Initially, this procedure was described using four or five ports; however, newer approaches use three-trocars aiming for minimal invasión,3,4 which may complicate the procedure. We present a video of the three-trocar technique step by step, with several tips and tricks to improve the performance. Patients and Methods: Seven patients (mean 44 years old range: 31–58) underwent Anderson-Hynes three-trocar LP for symptomatic UPJO. The three-port transperitoneal technique was done. A 10-mm trocar was placed directly through the umbilicus and two 5-mm trocars in a triangular arrangement. To improve exposure of the UPJ and reduce the dissection time, the surrounding tissues may be retracted with clips or sutures applying the puppet maneuver, with special caution to avoid incorporating the bowel into the retraction devices. The proximal ureter may be lifted with similar maneuver, like a suture sling to simplify the UPJ dissection and further on the spatulation.5 In some cases, kidney stones may be removed using a nephroscopy with carbon dioxide (CO2), inserting a flexible cystoscope into the renal pelvis. This technique may be applied to avoid accumulation of irrigation fluid into the peritoneal cavity, connecting the gas cannula to the irrigation channel of the endoscope to insufflate CO2. It works well for stones located in the anterior calicos, but is not useful in the posterior calicos.6 The ureteral spatulation may be simplified through stabilization of UPJ by the remaining attachment to the renal pelvis, by the suture sling of the ureter and by a grasper holding.7 The performance of the dismembered pyeloplasty may be improved and simplified applying the Hammock maneuver, which stabilizes the line of anastomosis anchoring the suture to the surrounding tissues with clips, with caution to avoid incorporating the bowel again. Finally, the percutaneus antegrade ureteral stent placement may be done through a 14-gauge angiocatheter,8,9 previous to complete the anastomosis. Results: The average operating time of the pyeloplasty was 187 minutes. No open conversions were required. There were no perioperative complications. Subjective and objective success was obtained in six of seven patients. Conclusions: The three-trocar LP is a secure and feasible technique for the correction of UPJO. The maneuvers shown in this video may simplify the procedure. No competing financial interests exist. Runtime of video: 9 mins 49 secs
