B超引导下经皮肾穿刺抽液加无水酒精注射治疗肾囊肿

Percutaneous Aspiration and Absolute Alcohol Injectionfor the Treatment of Renal Cyst under Ultrasound Guidance

Ｂ超引导下经皮肾囊肿穿刺抽液＋无水酒精囊内注射治疗肾囊肿患者３６例。男２２例，女１４例，平均年龄４７．８岁。单个囊肿者２９例，２～３个囊肿者４例，多囊肾者３例。囊肿直径平均５．０６ｃｍ（２～９ｃｍ），被抽出液量平均７５．３ｍｌ（１０～１８０ｍｌ），抽液后囊内注射无水酒精量（浓度为９９％）平均１６．６ｍｌ（３～４５ｍｌ）。穿刺均一次成功，仅２例有短暂酒醉感、３例有短时轻微血尿。穿刺后复查囊肿分别于第２～３个月时全部消失，随访１～２年无１例复发。本文还就该法的优点、操作技术要点、硬化剂选择及其用于治疗多囊肾的有关争论等作了讨论。

Since November 1990,36 patients with renal cysts have been treated with percutaneousaspiration and absolute alcohol injection under ultrasound guide. Of them 22 were males and14 females with an average of 47. 8 years.29 patients were with single cyst,4 with 2-3cysts and 3 with polycystic kidney;The diameter of the cysts averaged 5.06 cm(2-9cm),and the quantity of aspirates averaged 75.3 ml(10-180 ml).3-45 ml(16. 6 ml in average)absolute alcohol(99%)was injeted into the cysts after aspiration. Except 2 patients with alittle bit tipsy and 3 with slight hematurea for a short period, the rests were successful onthe first run, All the cysts disappeared respectively 2-3months after treatment.All pa-tients have been followed up by ultrasonography for 1-2years after treatment.There wasneither recurrence nor complication. The advantages and key steps of the operative method,selection of sclerosing agent and contentions about polycystic kidney were discussed.
