目的:观察使用液电碎石机对120例膀胱结石病人碎石的临床疗效。方法:对<3cm无禁忌症患者应用国产UL-Ⅲ型液电碎石治疗,电极头就超过膀胱镜镜窗1cm距结石缘2mm左右轰击,直到结石碎成3mm以下,整个过程约5～30min。结果:一次碎石成功者117例(95.7%),二次成功者2例(1.7%),1例因前列腺增生膀胱巨大结石伴感染而中断治疗。结论:膀胱液电碎石术治疗膀胱结石,疗效确切,操作简便,安全性大而痛苦少。 Objective: To observe the clinical effect of using lithotripsy on 120 patients with lithiasis. Methods: The patients with no contraindications of <3cm were treated with homemade UL-Ⅲ electrohydraulic lithotripsy. The tip of the electrode was more than 2cm away from the edge of the cystoscope window by 1mm until the stones were broken into 3mm, the whole process was about 5 ~ 30min . Results: 117 cases (95.7%) were successful in one gravel, 2 cases (1.7%) were successful in the second and one case was discontinued due to huge bladder stones with benign prostatic hyperplasia. Conclusion: Bladder electrohydraulic lithotripsy for the treatment of bladder stones is effective, easy to operate, safe and less painful.
