V10-06: Robotic-assisted Laparoscopic Calyceal Diverticulectomy

Video

INTRODUCTION

A calyceal diverticulum is a cystic cavity within the kidney that is lined by transitional epithelium and communicates with a calyx, or less commonly, with the renal pelvis. A calyceal diverticulum forms as a result of the failure of the degeneration of the ureteric bud. 0.2 – 0.5% are congenital; 40% are associated with calculi. This is a video demonstrating a robot assisted laparoscopic calyceal diverticulectomy._x000D_

METHODS

This video demonstrates two cases of robotic calyceal diverticulectomy the first patient is a 19 year-old caucasian female and the second patient is a 25 year-old caucasian female. Who both had sudden onset of flank pain and abdominal pain. Initial work up was consistent with infection; however on repeat imaging, both patients were found to have a calyceal diverticulum. Both patients underwent a robot assisted laparoscopic diverticulectomy. Initial dissection was similar to a partial nephrectomy with mobilization of the large bowel and exposure of the renal hilum. The diverticulum is then incised, drained, and excised to the infundibulum to prevent recurrence. Any remaining urothelium was fulgurated.

RESULTS

Both patients who underwent a robot assisted laparoscopic calyceal diverticulectomy are complication and re-admission free to date.

CONCLUSION

Robotic-assisted laparoscopic calyceal diverticulectomy is a feasible and safe option in the management of large persistent calyceal diverticulum.
