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.
