应用三腔高压水囊导管经尿道扩张术治疗前列腺增生症

Application of transurethral dilatation via using three-channel high pressure water capsulecatheter in the treatment of hyperplasia of prostate

目的探讨用三腔高压水囊导管经尿道扩张术治疗前列腺增生症的方法及疗效。方法2007年6月～2008年4月应用三腔高压水囊导管经尿道扩张治疗前列腺增生症22例。术前行常规体格检查。麻醉成功后，将三腔高压水囊导管插入膀胱，水囊定位在后尿道，向内囊注水至0．3MPa，再向外囊注水至0．3MPa，放内囊水至0．1MPa，接引流尿袋，固定水囊导管，持续扩张48小时。结果本组术后平均住院6～8天，三个月后随访，排尿均通畅，尿线粗而有力，最大尿流率〉14ml／s，膀胱残余尿〈20ml。有6例不完全性尿失禁，2天后自行恢复控尿。术后10个月随访5例，排尿粗畅，B超证实，前列腺重量较术前减轻10g左右，残余尿〈10ml。结论三腔高压水囊导管经尿道扩张术治疗前列腺增生症，具有安全微创，操作简单，住院时间短，远期疗效可靠且又经济等特点，是高龄体弱患者，因前列腺增生需解决其排尿困难的首选治疗。

Objective： To investigate the efficacy of transurethral dilatation via using three-channel high pressure water capsule catheter in the treatment of hyperplasia of prostate. Methods： From June 2007 to April 2008, 22 patients with hyperplasia of prostate received transurethral dilatation via using three-channel high pressure water capsule catheter. Results： The stay was 6-8 days. Follow-up was performed 3 months later. The patients showed smooth emiction with a maximum flow rate more than 14 ml/s and a residual urine less than 20 ml. Conclusion： As the characteristics of safety, minimal invasion, simpleness, short stay, good efficacy, transurethral dilatation via using three-channel high pressure water capsule catheter could be the first choice for patients with hyperplasia of prostate.
