Percutaneous cystolithotomy after augmentation cystoplasty: comparison with open procedures.

Percutaneous procedures for the removal of calculi from reconstructed bladders have not been compared in a single institution with traditional open methods. The records of patients undergoing seven percutaneous and six open procedures for the removal of calculi from augmented bladders were reviewed. Operative time, hospitalization time, complications, stone burden, and recurrence were compared. All patients were stone-free at the end of either one or two procedures. Four of six patients in the percutaneous group and four of six patients in the open group had recurrent bladder calculi during average follow-up of 30 months. The average hospital stay was 1.1 days for patients undergoing percutaneous procedures and 3.7 days for those undergoing open cystolithotomy. Narcotic use was significantly lower in the percutaneous group. Percutaneous cystolithotomy is safe, effective, and currently the preferred method for removing stones from an augmented bladder.
