[Percutaneous removal of a large calculus in Indiana pouch using a laparoscopic entrapment bag].

A 67-year-old man was referred to our hospital for evaluation of large urinary-diversion calculus. He had undergone urinary diversion for invasive bladder cancer with an Indiana pouch, when he was 52 years old. We performed the surgery using a laparoscopic trocar and an entrapment bag, for reducing the risk of bladder damage by the lithoclast and small residual fragments of the calculus.
