摘要

對於有下泌尿道症狀的男性，經直腸超音波最主要的檢查工具，然而此工具對於膀胱腫瘤的診斷角色尚有爭議。我們報告一位男性病患罹患數年之久的排尿障礙及血尿，經藥物治療無效。在接受經直腸超音波檢查攝護腺時意外看到在膀胱頸部有一個腫瘤，其作用像一個閥門，造成膀胱出口阻塞，在手術切除後，病患的排尿困難及顯微血尿也立刻獲得改善，病理報告為到生性乳頭瘤。我們覺得經直腸超音波在診斷膀胱後壁及膀胱頸腫瘤上或許可以扮演一些角色。

Transrectal ultrasonography (TRUS) is the main tool for evaluation of prostate in men with lower urinary tract symptoms (LUTS). The role of TRUS in the diagnosis of bladder neoplasm is controversial. We describe a male patient presented with urinary difficulty and hematuria for several years. He accepted medical treatment but the response was poor. We found an incidental neoplasm in the bladder neck by TRUS during prostate workup. It worked as a check-valve that caused bladder outlet obstruction. The symptoms improved after tumor removal immediately. The pathology showed inverted papilloma of the bladder neck. We suggested that TRUS may play some role in the diagnosis of bladder neoplasm in posterior bladder wall and bladder neck.
