Leiomyoma of the bladder causing bilateral hydronephrosis: a case report.
We report a case of bladder leiomyoma with marked bilateral hydronephrosis caused by chronic urinary retention. Surgical finding was that the mass was smooth, fist-sized and had a thin stalk connected to the bladder wall. The tumor was completely removed. Histopathological diagnosis was leiomyoma of the bladder and the post-operative course was uneventful.
