Purpose: Although vesical calculi are routinely treated transurethrally, open vesicolithotomy is generally performed in patients with an impassable or surgically ablated urethra. We describe a technique of percutaneous vesicolithotomy which we used in patients who had undergone urethral ablation and concomitant continent diversion by appendicovesicostomy. Materials and Methods: Bladder stones were detected in 3 patients with neurogenic bladder who had undergone continent urinary diversion with bladder neck closure and appendicovesicostomy. To treat the stones access to the bladder was achieved percutaneously and the tract was enlarged using a balloon dilator. An Amplatz sheath was slipped over the inflated balloon and after the dilator was removed the sheath provided a working channel through which stones were fragmented and removed using a nephroscope. Results: Each patient was rendered stone-free and discharged home the same day as the procedure. Conclusions: Percutaneous vesicolithotomy provides an alternative approach for bladder stone removal in patients with an impassable urethra with decreased morbidity compared to open procedures.
