目的 评价超声引导下肾囊肿硬化剂治疗的疗效。方法 13例15个肾囊肿用18—20GPTC针穿刺抽吸,并注入99.5％酒精到囊腔,囊腔大小直径为4.5cm～14cm,抽出囊液为48ml～1370ml。结果 本组随访病例为11例13个囊腔,随访时间为1个月～3年,疗效为100％,其中囊腔消失占46％。并发症仅为腹部疼痛。结论 超声引导下经皮细针穿刺硬化剂治疗肾囊肿已成为一种有价值的方法。此法安全、并发症少且疗效好。 Objective To evaluate the curative effect of ultrasound-guided renal cyst sclerotherapy. Methods Thirteen 15 renal cysts were aspirated with 18-20 GPTC needle and injected with 99.5% alcohol into the cyst cavity. The cyst size was 4.5cm ~ 14cm, and the cyst fluid was withdrawn from 48ml ~ 1370ml. Results The follow-up cases of this group were 11 cases of 13 cysts. The follow-up time ranged from 1 month to 3 years. The curative effect was 100%, of which the cyst disappeared 46%. Complications are only abdominal pain. Conclusion Ultrasound-guided percutaneous fine needle puncture sclerotherapy for renal cysts has become a valuable method. This method is safe, less complications and good effect.
