Retroperitoneoscopic management of caliceal diverticular calculi.

INTRODUCTION

The management of caliceal diverticular calculi has changed from an open surgical approach to endoscopic management.

TECHNICAL CONSIDERATIONS: Different minimally invasive treatment modalities, such as extracorporeal shock wave lithotripsy, ureteroscopy, percutaneous nephrolithotomy, laparoscopy, and retroperitoneoscopy, can be offered to the patient. We report on a retroperitoneoscopic operative technique using endosonography for location and performing nephrotomy with complete excision of the caliceal diverticulum and ligation of the diverticular neck with an Endo-loop.

CONCLUSIONS

The advantages of this minimally invasive technique include total excision of the diverticulum with no risk of recurrence and easy and complete closure of the diverticular neck.
