摘　　要：目的 探讨CT引导下穿刺注射无水乙醇治疗肾盂旁囊肿的临床应用价值和操作技巧。方法 回顾性分析21例肾盂旁囊肿病例，经CT尿路造影（CT Urography，CTU）确诊，行CT引导下穿刺注射无水乙醇治疗，追踪观察疗效及并发症。结果 21例均一次穿刺成功，2例出现肾实质肾包膜下少量出血；8例患者注射无水乙醇时出现疼痛，3- 5 min后缓解；3个月后复查CT，疗效评价：0级1例，Ⅰ级2例，Ⅱ级5例，Ⅲ级13例，多在术后3 ～ 6个月时囊肿消失。随访2个月 -2年，囊肿无复发。结论 CT引导下穿刺注射无水乙醇治疗肾盂旁囊肿，定位精确，操作简便，并发症少，疗效确切。Objective To explore the clinical value of CT- guided percutaneous puncturing and injection of absolute alcohol in treating parapelvic cysts, and to discuss its technical points. Methods A total of 21 patients with parapelvic cyst were enrolled in this study. The diagnosis was confirmed by CT urography in all patients. CT-guided percutaneous puncturing and injection of absolute alcohol was carried out. The clinical results and complications were analyzed. Results Successful puncturing with single procedure was obtained in all the 21 patients. Two patients had renal subcapsular and parenchymal hemorrhage in small quantities. Eight patients experienced pain during the injection of ethanol, which was relieved in 3 - 5 minutes. Re-examination with CT three months later in order to evaluate the therapeutic results showed that grade 0 was obtained in one, grade I in 2, grade II in 5 and grade III in 13 cases. Most cysts disappeared within 3 - 6 months. The patients were followed up for 2 - 24 months and no recurrence of cyst was seen. Conclusion For the treatment of parapelvic cysts, CT-guided percutaneous puncturing and injection of absolute alcohol can locate the lesion precisely. The therapeutic effect is reliable and the manipulation is simple with fewer complications.
