インディアナパウチ内結石の再発に対して開放結石摘出術を施行した1例

Abstract

The patient was a 70-year-old male who underwent radical cystectomy and Indiana pouch construction for bladder cancer in March 1996. The first incidence of stone formation within the pouch occurred two years postoperatively, and was treated by endoscopic lithotripsy. Over the next decade, the patients required six additional endoscopic lithotripsies and two open poucholithotomy for stone removal. Recently, a recurrent stone grew to 50 mm in diameter, causing catheterization difficulties, and surgical intervention was performed. To extend the interval before future treatment, we performed open poucholithotomy, achieving stone-free status. The patient did not require additional treatments for 64 months postoperatively.
