急诊内镜治疗输尿管结石并肾绞痛疗效观察

目的　评价输尿管镜术急诊治疗输尿管结石并肾绞痛的疗效。方法　总结应用输尿管镜取石、碎石术治疗 1 0 7例输尿管结石并肾绞痛患者的资料 ,并对提高单次取石和碎石成功率进行讨论。结果　 86例输尿管结石原位 1次取石、碎石成功 ,1 6例结石被冲入肾盂 (有 2例继在肾盂内行钬激光碎石术获成功 ) ,2例发生输尿管穿孔改行开放手术 ,3例因输尿管下段特别细小经输尿管扩张 1周后再行内镜治疗成功。术后结石梗阻解除率为 95.3% (1 0 2 /1 0 7) ,单次取石或碎石成功率为 82 .2 % (88/1 0 7)。术后残石排净时间平均 2 .1周 ,术后无明显血尿、梗阻性脓肾等并发症发生。结论　输尿管镜术可作为输尿管结石并肾绞痛治疗的有效方法之一。

Study of treating ureteral calculi with renal colic using ureteroscopy in emergency

Objective To evaluate the clinical effects of ureteroscopy in emergency on the treatment of ureter calculi with renal colic. Methods 107 cases of ureter calculi via ureteroscope with EMS Pneumatic lithotriptor or OMNIPULSE TM Ho: YAG lithotriptor were retrospectively analyzed. Results 86 cases were taken out or fragmented in situ after a single session. 2 of the 16 cases flushed to the pelvis renalis in the procedure were fragmented successfully in the pelvis. Uretel perforation occurred 2 and 3 cases failed in the procedure. The successful obstruction relieving rate of one 1 procedure was 95.3% (102/107). The mean expectoration time of calculi free was 2.1 weeks. Conclusions Ureteroscopy is one of the best choices to ureteral calculi with renal colic when good techniques under ureteropyeloscope are provided.
