Background: The video shows a 41-year-old female with a long standing history of left flank pain secondary to renal stone disease. Prior stone treatment with ESWL and ureteroscopy had been unsuccessful, given their location within a calyceal diverticulum. She then underwent laparoscopic calyceal diverticulectomy with removal of renal stones.
Methods: The left kidney was mobilized in standard laparoscopic fashion. Intraoperative ultrasound was used to identify the calyceal diverticulum. The diverticulum was entered and the stones were removed. The renal artery was clamped to control bleeding from the bed of the diverticulum. The remainder of the diverticulum was fulgurated and removed. A boster was then placed within the renal parenchyma. Post-operatively a stent, drain, and foley catheter were placed.
Results: The patient's creatinine remained stable post-operatively. She was discharged from the hosital on post-operative day three. In follow up, her flank pain has since resolved.
Conclusions: Laparoscopy can successfully treat stone disease in the setting of a calyceal diverticulum.
