双极等离子体治疗尿道狭窄与闭锁的临床疗效分析(附76例报告)

目的探讨双极等离子体治疗尿道狭窄与闭锁的安全性和有效性。方法对纳入者按入院先后顺序以(1∶1)比例随机分为冷刀切开加电切术组和双极等离子体治疗组,对术前术后尿流率变化及手术并发症进行观察随访比较。结果76例患者手术均获成功,2组在平均手术时间、术前最大尿流率和残余尿及随访术后3个月最大尿流率和残余尿方面无统计学意义;术中平均出血量、随访术后1年、2年最大尿流率和残余尿、再手术率及尿扩发生率方面具有统计学意义(P<0.05)。结论双极等离子体治疗尿道狭窄与闭锁近期疗效与冷刀切开加电切相当,远期疗效优于冷刀切开加电切组;经尿道等离子体双极电切术可以作为治疗尿道狭窄与闭锁的首选手术方法。

Clinical study of endourethral surgery for urethrostenosis and urethratresia by bipolar plasmakinetic

Objective To investigate the efficacy and safety of endourethral surgery for urethrostenosis and urethratresia by bipolar plasmakinetic.Methods 76 cases of urethrostenosis and urethratresia patients were chosen and divided randomly(1:1 in accordance with the time of hospitalization)into two groups:internal urethrotomy transurethral scar resection group and bipolar plasmakinetic group,and followed up the maximun flow rate(MFR)and full details of each operation were assessed post operatively.Results All the patients underwent endourethral surgery successfully by two different methods and no difference in mean operation time,preoperative MFR and RU and postoperative three months MFR and RU,but as to mean blood loss,postoperative one year and two year MFR and RU,twice times operation and intermittent dilation was other way around(P <0.05).Conclusions In a view of the efficacy and safety of endourethral surgery for urethrostenosis and urethratresia,bipolar plasmakinetic superior to internal urethrotomy transurethral scar resection on the long run,and bipolar plasmakinetic were believed to be first choice for the treatment of urethrostenosis and urethratresia.
