【摘要】：目的探討點觸式探針在鑄型結(jié)石超聲碎石清石手術(shù)的安全性與可行性。方法將45例腎鑄型結(jié)石隨機分成兩組,觀察組22例,對照組23例。兩組分別用點觸式探針和原平面超聲探針行經(jīng)皮腎鏡超聲碎石清石術(shù)。術(shù)中觀察兩種探針對尿路黏膜損傷情況,并準確記錄碎石時間和結(jié)石體積,計算碎石清石速度。結(jié)果點觸式探針的碎石清石時間和速度明顯優(yōu)于平面探針(P0.05),其速度是原超聲探針的1.9倍。對照組出現(xiàn)多例輕微的黏膜吸附傷,無需處理,觀察組未出現(xiàn)尿路黏膜吸附傷和刺傷。觀察組和對照組結(jié)石清石率分別為95.45%(21/22)和91.33%(21/23),兩組差異無統(tǒng)計學意義。結(jié)論點觸式探針碎石速度快,效率高,安全性好,有較好的臨床推廣應(yīng)用價值。
[Abstract]:Objective to investigate the safety and feasibility of point-touch probe in ultrasonic lithotripsy for cast stone. Methods 45 cases of renal cast stones were randomly divided into two groups: observation group (n = 22) and control group (n = 23). Two groups were treated by percutaneous nephroscopic lithotripsy with point touch probe and original plane ultrasonic probe. Intraoperative observation of urinary tract mucosal injury with two probes, accurate recording of lithotripsy time and volume of stone, and calculation of lithotripsy clearance speed. Results the lithotripsy time and velocity of point touch probe were better than that of planar probe (P0.05), and the velocity was 1.9 times of that of the original ultrasonic probe. In the control group, there were several slight mucosal adhesion injuries without treatment, and no urinary mucosal adhesion injury or stab injury was found in the observation group. The stone removal rates of observation group and control group were 95.45% (21 / 22) and 91.33% (21 / 23) respectively. Conclusion Point-touch probe lithotripsy has the advantages of high speed, high efficiency, good safety and good clinical application value.
