直肠癌腹会阴联合切除术前后的尿动力学研究

Urodynamic study before and after abdominoperineal resection of the rectum for rectal carcinoma

２０例连续收治的直肠癌患者（男１３例，女７例）在行腹会阴联合切除术前和术后１３ｄ及６个月分别进行了尿动力学检查。尿动力学研究包括尿流率、膀胱压力图、尿道压力图及Ｌａｐｉｄ试验。结果发现尽管手术后排尿障碍很常见，但大多数都是暂时的。重要的是应注意区别暂时性和持久性排尿障碍。手术后期才出现的排尿障碍，提示有肿瘤复发的可能。尿动力学检查对于直肠癌根治术后排尿障碍的诊断和治疗都有很重要的意义。

Twenty patients,13 male and 7 female,were urodynamically investigated before and 13 days and 6 months after they underwent abdorninoperineal resection of the rectum because of rectal carcinoma. Urodynamic study consisted of the determination of urinary flow rate,the pressure changes in the urinary bladder and urethrae and lapid test.It was found that bladder dysfunction with subsequent difficulty in urination was frequently encounted and was temporary in most of the cases,It was essential to differentiate whether urination difficulty was tempory or persistent. Urination difficulty occurred in the late postoperative stage implicated the possibility of the recurrence of the carcinoma.It was concluded that urodynamic study was of significance for the diagnosis and treatment of urination difficulty after abdominoperineal resection of the rectum for rectal carcinoma.
