我們報告這個少見的尿道休憩室癌病例及不尋常的診斷治療過程。這個病例首先以一般的膀胱尿道X光攝影診斷為尿道憩室症，我們以超音波診斷為尿道憩室癌。一般尿道憩室癌的治療為膀胱尿道切除術。我們採膀胱保留及廣泛尿道（及部份陰道）切除手術。這不同尋常的診斷治療方式導致長期（7年尚未復發）根治效果。

We describe our experience using color Doppler ultrasound and endoscopy with a pediatric cystoscope to diagnose urethral diverticular cancer previously undetected by a voiding cystourethrogram in a 43-year-old woman. We then carried out a radical excision of the urethral and periurethral tissues including the anterior 1/2 of the vagina while sparing the bladder. The patient has been followed-up for 7 years with no evidence of cancer recurrence.
