Percutaneous treatment of calculi in reconstructed bladder.

PURPOSE: To report our results with percutaneous removal of calculi from reconstructed bladders.

PATIENTS AND METHODS: Twelve patients with reconstructed bladders who underwent endoscopic cystolithotomy were identified from our departmental database, and retrospective review of case notes and imaging was performed.

RESULTS: Access was gained via an ultrasound-guided new tract in 9 patients (75%). An old suprapubic tract site was used in two patients, and the Mitrofanoff stoma was the route of access in one patient. The procedure was successful, with stone clearance achieved in all 12 cases. No major complications were observed. At a median follow up of 24 months, stone recurrence was observed in 5 patients (42%), 4 of whom underwent repeat procedures. Follow-up showed no change in continence in the patient with a Mitroffanoff stoma.

CONCLUSION: Percutaneous cystolithotomy is a safe and effective minimally invasive option for removal of stones in a reconstructed bladder. We recommend endoscopic removal as the treatment of choice in these patients.
