目的:观察比较电切镜内外鞘置入对经尿道前列腺电切术(TURP)后球膜部尿道狭窄的影响。方法:将拟行TURP620例分为观察组240例和对照组380例;观察组采用内鞘25mm周径电切镜间断放液方式,对照组采用电切镜带外鞘27mm周径电切镜循环灌洗方式。比较两组手术时间、估计失血量、前列腺标本量以及术后膀胱冲洗时间、尿管留置时间、电切综合征发生率和球膜部尿道狭窄发生率。结果:两组手术时间、估计失血量、前列腺标本量以及术后膀胱冲洗时间、尿管留置时间、电切综合征发生率均差异不显著(P>0.05);观察组术后球膜部尿道狭窄发生率2.5%,显著低于对照组的6.3%(P<0.05)。结论:电切镜去外鞘行TURP可显著降低术后球膜部尿道狭窄发生率。
OBJECTIVE: To observe the effect of external and internal sheath incision on ureteral stenosis after transurethral resection of prostate (TURP). Methods: The TURP620 cases were divided into observation group of 240 cases and control group of 380 cases; the observation group were treated with 25mm peripheral sheath sheath resection intermittent discharge mode, the control group with resectoscope with sheath 27mm circumference resectoscope Cyclic irrigation method. The operation time, blood loss, prostate specimen volume, postoperative bladder irrigation time, catheter indwelling time, the incidence of resection syndrome and the incidence of urethral stenosis were compared between the two groups. Results: There was no significant difference in operative time, blood loss, prostatic specimen volume, postoperative bladder irrigation time, catheter indwelling time, and the incidence of resection syndrome (P> 0.05) The prevalence of stenosis was 2.5%, significantly lower than that of the control group (6.3%, P <0.05). Conclusions: The resectable TURP with resectoscope can significantly reduce the incidence of urethral stricture in the posterior portion of the sphenoid membrane.
