研究目的:

通过前瞻性随机区组对照临床试验研究,验证经会阴部尿道狭窄吻合术联合尿道局部注射维拉帕米对术后尿道瘢痕增生的抑制作用。  

Objectives of Study:

By conducting a prospective randomized clinical trial, this study aims to evaluate the anti-fibrosis effect of verapamil on urethral and periurethral area after transperineal anastomosis of urethral stricture patients.

药物成份或治疗方案详述:

本研究拟计划招募纳入前尿道狭窄患者32人,后尿道狭窄患者32人。按照既往所接受尿道操作次数的多少,将操作次数相近的患者分为一个区组,前、后尿道狭窄患者各自分为4个区组。在其基础上各区组进一步分为试验组与对照组,其中试验组术中及术后第2、4、6、8、10周接受尿道吻合口部位2ml维拉帕米浸润注射治疗,对照组仅接受手术治疗。术后第12周对所有患者进行尿道瘢痕触诊长横径测量、尿道造影下测量尿道最窄内径、最大尿流率检测、阴茎彩超弹性成像下以及会阴部核磁共振下检测尿道瘢痕程度。从以上4个方面评估维拉帕米抑制瘢痕疗效。 

Description for medicine or protocol of treatment in detail:

This study is planed to enroll 32 anterior urethral stricture patients and 32 posterior urethral stricture patients. The two groups with different lesion sites will be divided into 4 blocks respectively, ensuring the times of previous urethral operations of each patient in one block are similar with others. Every block is further randomly divided into experimental and control groups, and experimental groups will undertake 2ml injection of verapamil around the anastomosis site of urethra intraoperatively and postoperatively (injected in 2,4,6,8 and 10 weeks after the surgery), while the control groups will only receive the anastomosis surgery. All of the patients will be arranged palpation of urethral scar range, measurement of narrowest urethral inner diameter, examination of urine flow rate (Qmax),ultrasound and nuclear magnetic resonance assessment of urethral scar range after 12 weeks of surgery to evaluate the effect of verapamil.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用随机区组设计,将既往患者接受的尿道操作次数作为区组变量,将次数相近的人分为一个区组。前后尿道患者各按既往操作次数的多少,从小到大依次排列,之后均分为4个区组,每个区组内包含8名受试者。区组内再继续随机分配为试验组与对照组,具体方法为,从随机数字表中任选一行数字,从左向右获得8个随机数字并分别依次对应8名收试患者,再将每名患者的随机数字除以组数2,记录各自所得余数(若整除则记余数为组数2),余数为1的分为试验组,余数为2的分为对照组。若分组后两组患者数不同,则最后进行调整,选取随机数字表中下一个随机数字,除以组数2,得到的余数作为序号,将患者数较多组中该序号对应的患者移到患者数较少的一组,直至两组人数相等。

Randomization Procedure (please state who generates the random number sequence and by what method):

The experiment is carried out by random block design,which will divide anterior and posterior urethral stricture patients into 4 blocks respectively, guaranteeing the times of previous urethral operations of each patient in one block are similar with others.Every block has 8 patients,all of them will be given a
