Retroperitoneoscopic treatment of ureteral invagination caused by a long fibroepithelial polyp protruding into the bladder: report of a case.

We describe how we performed retroperitoneoscopic surgery for a 15.5-cm fibroepithelial polyp, which originated in the lowest portion of the right upper ureter, protruded intermittently into the bladder, and caused ureteral invagination. To our knowledge, this is the first report of the retroperitoneoscopic management of ureteral invagination caused by a long fibroepithelial polyp.
