A successful open neocystolithotomy in studer neobladder with Mitrofanoff for multiple large neobladder stones: A case report and review of the literature

Abstract

Urolithiasis is a rare complication of orthotopic neobladder after cystectomy. We report a case of a 25-year-old female with studer neobladder and Monti valve presenting with recurrent urinary tract infections, abdominal pain, and difficult catheterization. Imaging revealed multiple large stones in the neobladder. Neocystolitholapaxy and neocystolithotripsy failed, leading to an open neocystolithotomy with retrieval of 14 large stones. Stone composition analysis showed struvite (30%), carbonate apatite (46%), and whitlockite (24%). Neobladder repair with omental interposition was performed. Follow-up confirmed an intact neobladder without leaks. Neobladder stones may be asymptomatic, and open neocystolithotomy is an effective treatment for multiple neobladder stones.
