超声引导下穿刺肾囊肿乙醇硬化治疗的评价

Evaluation of Sclerotherapy with Alcohol for Renal Cysts by Ultrasound-Guided Puncture

目的 探讨超声引导下穿刺注射99．9％乙醇治疗肾囊肿的作用。方法 采用超声对26例肾囊肿行定位穿刺抽液和注入99．9％乙醇，治疗前、后测量并比较惠肾主动脉及囊肿毗邻处动静脉血流，设对照组20例。随访6个月-1年。结果 超声引导下共治疗26例囊肿，5例未完全消失，进行2次治疗，共穿刺31次，无严重并发症；治疗前、后患肾段动脉流速及阻力指数（RI）间差异有显著性意义（P〈0．05）。结论 超声引导下穿刺注射99．9％乙醇治疗肾囊肿是一种安全、微创、高效、经济的治疗方法；多普勒频谱检测肾血流有助于了解肾囊肿对肾脏的影响。

Objective To evaluate the effect of sclerotherapy with 99. 9% alcohol injection after puncture and aspiration guided by ultrasound for the treatment of renal cysts. Methods Totally 26 cases with symptomatic renal cysts were treated with sclerotherapy with 99. 9% alcohol injection after puncture and aspiration guided by ultrasound. The blood flow of the main renal artery and segmental renal vessels before and after the sclerotherapy were measured by Doppler spectrum, meanwhile, another 20 cases were chosen as controls. The follow - up was conducted for half to a year. Results There were 5 cases whose cysts did not disappear and were treated again, and no serious complication was found. The blood flow of segmental renal artery increased, and the resistive index decreased significantly after therapy （ P 〈0. 05 ）. Conclusion The sclerotherapy with 99. 9% alcohol by ultrasound - guided puncture is a safe, minimally invasive, highly effective, and inexpensive method for treatment of symptomatic renal cysts. Measurement of renal blood flow by Doppler spectrum is useful to know the impact of cyst on the kidney.
