The percutaneous treatment of simple renal cysts must be restricted to symptomatic lesions. It consists in a guided puncture, fluid aspiration and the injection of a sclerosing agent. The authors describe the procedure they followed, which has been made possible by technical progress. It consists in US guidance, a Trocar catheter drainage set and the injection of absolute alcohol. Moreover, the long-term results are reported of a retrospective study of 69/148 treated patients who underwent one or more US exams 15 days to 5 years after the procedure. Eleven of 69 patients (15.9%) exhibited complete regression, 42 of 69 (60.9%) had lesion relapse < 5 cm phi and 16 of 69 (23.2%) had > 5 cm relapse. On the whole, 53 (76.8%) positive results were obtained after the first treatment; positive results were obtained after the second treatment in 4 of 16 patients with > 5 cm relapse. US follow-up showed changes in the sizes of the relapsed cysts, which sometimes shrunk in the long run. All treated cysts reduced in volume; nevertheless, it would be useful to look for new sclerosing agents allowing a higher rate of complete regressions.
单纯性肾囊肿的经皮治疗必须限于有症状的病变。其操作包括在超声引导下穿刺、抽吸囊液并注入硬化剂。作者描述了他们采用的治疗方法，技术进步使该方法成为可能。具体包括超声引导、套管针导管引流装置及注入无水乙醇。此外，报告了对69例接受治疗的患者进行回顾性研究的长期结果，这些患者在治疗后15天至5年接受了一次或多次超声检查。69例患者中，11例（15.9%）囊肿完全消退，42例（60.9%）复发囊肿直径<5 cm，16例（23.2%）复发囊肿直径>5 cm。总体而言，首次治疗后53例（76.8%）取得阳性结果；16例复发囊肿直径>5 cm的患者中，4例在第二次治疗后取得阳性结果。超声随访显示复发囊肿大小有变化，有些囊肿最终会缩小。所有治疗的囊肿体积均减小；然而，寻找能提高完全消退率的新型硬化剂将是有益的。
