Laparoscopic management of urolithiasis in a continent urostomy.

BACKGROUND

Urinary calculi formation is an infrequent but challenging late complication of continent urostomy. Percutaneous endoscopic management of two patients with symptomatic pouch urolithiasis is described.

CASES: A 48-year-old woman with a history of cervical squamous cell carcinoma (SCC) treated with primary chemoradiotherapy presented with recurrent pain and urinary tract infections (pouchitis). She had undergone continent urostomy 4 years previously for management of a vesicovaginal fistula. A 59-year-old woman following exenteration with continent diversion for recurrent cervix SCC had a 6-month history of refractory pouchitis. In both women, multiple pouch urinary calculi were identified. Their continent reservoirs were, in part, created using titanium staplers. Percutaneous CO(2) endoscopy afforded identification and removal of their stones and staples without complication.

CONCLUSION

Successful treatment of continent urostomy urolithiasis is accomplished by percutaneous endoscopy.
