Urethroscopy is an important method to diagnose and treat urethral CA and urethrotomy should be avoided as possible in the treatment of urethral CA. Intraurethral instillation and local therapy of 5 % 5-fluorouracil solution can prevent subclinical infection of human papillomavirus .

结论 尿道 镜 检查是诊断治疗尿道CA的最重要手段，尽量避免采取尿道切开方法治疗尿道CA，5%5-FU局部浸泡和尿道灌注可治疗人乳头瘤病毒（HPV）的亚临床感染，预防复发。

Methods 17 senile patients who were diagnosed by clinical manifestations and urethroscopy and pathology were divided into the urethrotomy group and 5-FU group .

方法临床、 尿道 镜及病理学诊断的17例老年 尿道 CA病人分成尿道切开组和5-氟尿嘧啶（5-FU）组。

The patients were followed-up for 6 ~ 36 months ( 17 months on average ) by retrograde urethrography urethroscopy and uroflometry .

术后随访时分别行逆行尿道造影， 尿道 镜和尿流率检查。结果本组患者术后随访6～36个月，平均17个月。

Methods w_566 31 cases were underwent urethroscopy and replaced catheter periodically after internal urethrotomy of urethral stricture the conditions of urethral healing were observed follow-up .

方法对31例尿道狭窄内切开术后的患者进行定期 尿道 镜 检及更换 支架导尿管，对术后尿道愈合进行连续观察。

Urethroscopy can offer the reliable basis for whether continuing keeping the catheter or not .

结论 支架导尿管留置 时间 与 尿道 愈合及疗效 呈正相关关系， 尿道 镜 检可为是否继续留置支架导尿管提供可靠依据。

Conclusions : Urethroscopy is superior to cystourethrography in diagnosis of anterior urethral valve .
