作者对１０５例尿道结石患者取石时技术进行了改进。方法：前尿道结石者取仰卧或坐位，后尿道结石者取左侧卧位。常规消毒铺巾，向尿道内注入０．５％地卡因２ｍｌ作表面麻醉，术者戴无菌手套，将胆道取石钳涂拭无菌石蜡油后徐徐插入尿道，当钳尖碰到结石后，稍张开钳齿将结石前部钳住，稍作转动缓慢取出。后尿道结石不易钳取，宜用下述方法：术者右手持钳，左手或助手戴手套用示指进直肠内抵住前列腺部尿道，从尿道外口注入尿道软扩张合剂（地塞米松４ｍｇ、庆大霉素４万单位、１％普鲁卡因１０ｍｌ混合液）充盈尿道。取石过程中置于直肠内的手指协助将结石固定并送入钳齿窝内，右手将已钳住结石的钳子左右旋动缓慢取出。较难取出者可术中追加一次尿道粘膜麻醉剂，同时向尿道内注入无菌石蜡油１０ｍｌ继续取石则可成功。
The author of 105 cases of urethral stone in patients with stone technology improved. Methods: Anterior urethral calculi who take supine or sitting, urethral calculi who take the left lateral position. Conventional disinfection shop towels, urethral injection of 0.5% tetracaine 2ml for surface anesthesia, the surgeon wearing sterile gloves, the biliary lithotomy with sterile paraffin oil, slowly inserted into the urethra, when the pliers hit the stones Slightly open the clamp teeth to clamp the front of the stone, a little slow rotation out.
