Leiomyoma of the Bladder Causing Ureteral Outlet Obstruction: A Case Report and Review of the Literature

膀胱平滑肌瘤是一種少見的間葉細胞瘤，約僅佔所有膀胱腫瘤的百分之零點五。好發於女性，女比男約3:1，致病原因仍然不明；臨床上表現出來的症狀主要和腫瘤大小及所在位置有關，可以超音波，電腦斷層，膀胱造影，或經尿道膀胱鏡診斷之。至於治療方面，無症狀的患者並不一定要手術，腫瘤較小可以經尿道膀胱鏡手術摘除之。若是腫瘤太大則考慮剖腹探查摘除。預後良好，並無轉變成惡性之報告。據現有文獻記載，此腫瘤在臨床上主要表現是膀胱出口阻塞，少有輸尿管阻塞的現象；最近，我們成功地治療一女性患有膀胱平滑肌瘤並造成右側輸尿管阻塞合併腎臟水腫，術後六個月腎臟水腫完全消失，並且無復發之跡象。

Benign mesenchymal tumors of the bladder are rare. Leiomyoma is the mesenchymal tumor of the bladder with accounts for less than 0.5% of all bladder tumors. These tumors have a 3:1 female-to-male predominance, with symptoms at a rate primarily related to their location and secondarily to their size. They infrequently cause ureteral obstruction. Recently we treated a patient with leiomyoma of the bladder causing ureteral obstruction and hydronephrosis. Intravenous urography and C. T. of pelvis comfirmed right hydronephrosis and the tumor of bladder. Cystoscopy showed a submucosal mass in right posterior wall of bladder with compression of right ureteral orifice. The patient was cured with partial cystectomy and ureteroneocystostomy.
