成人尿道上皮息肉是一種少見的疾病。我們報告一例成人前列腺尿道上皮息肉，有一長莖，從近膀胱頸處的前列腺尿道長出，而凸出到球狀尿道處。臨床上表現以間歇性尿失禁為主；此病人接受經尿道內視鏡息肉切除手術，成功地將息肉切除，術候症狀明顯改善，三個月後尿道膀胱鏡追蹤檢查無復發之現象。我們並且回顧文獻。

Epithelial polyps of the urethra in adults are uncommon lesions. We reported a case with a solitary long and pedunculated polyp of prostatic urethra with intermittent urinary leakage in whom transurethral resection was done successfully. The symptoms improved after removal of the polyp. Cystourethroscopy done three months later found no evidence of recurrence.
