CT导向下采用监测乙醇浓度硬化治疗单纯性肾囊肿的临床经验

目的:评价CT导向下采用监测乙醇浓度硬化治疗单纯性肾囊肿的安全性、有效性。方法:2006年5月²011年6月,67例患者69个单纯性肾囊肿在我院行CT导向下抽吸及无水乙醇硬化治疗。治疗时监测注入囊内乙醇CT值的变化,当CT值小于或等于-190 HU时,保留10 min后将液体抽尽。治愈:囊肿消失;有效:囊肿直径缩小50%以上;无效:囊肿直径缩小小于50%。结果:67例患者69个单纯性肾囊肿均成功行CT导向下抽吸及无水乙醇硬化治疗。治愈56例(81.2%),有效10例(14.5%),无效3例(4.3%)。囊肿平均直径从术前7.2 cm(范围42011年6月,67例患者69个单纯性肾囊肿在我院行CT导向下抽吸及无水乙醇硬化治疗。治疗时监测注入囊内乙醇CT值的变化,当CT值小于或等于-190 HU时,保留10 min后将液体抽尽。治愈:囊肿消失;有效:囊肿直径缩小50%以上;无效:囊肿直径缩小小于50%。结果:67例患者69个单纯性肾囊肿均成功行CT导向下抽吸及无水乙醇硬化治疗。治愈56例(81.2%),有效10例(14.5%),无效3例(4.3%)。囊肿平均直径从术前7.2 cm(范围4¹3 cm)缩小至术后1.5 cm(范围013 cm)缩小至术后1.5 cm(范围0⁵ cm;P<0.001)。其中2例患者术后出现低热。结论:CT导向下采用监测乙醇浓度硬化治疗单纯性肾囊肿是一种简单、安全、有效的微创治疗方法。

Clinical experience of CT-guided sclerotherapy with ethanol concentration monitoring for the treatment of simple renal cysts

Objective：Evaluate the safety and efficacy of ethanol sclerotherapy with ethanol concentration monitoring for the hardening treatment of simple renal cyst.Methods：67 patients with 69 simple renal cysts were treated with CT-guided suction and absolute ethanol from May 2006 to June 2011.The CT density value of injected capsular ethanol was monitored during the procedure.If the CT density value of cyst fluid was less than or equal to -190 HU,ethanol injected was completely removed after 10 minutes.The disappearance of the renal cyst was considered to be complete regression.The reduction in the diameter of the cyst by more than one half was considered partial regression.The treatment was considered as a failure when the cyst recurred and developed into more than one half of the diameter before the treatment.Results：Sclerotherapy with absolute ethanol was performed successfully in all 67 patients with 69 simple renal cysts.Complete and partial resolution occorred in 56（81.2%） and 10（14.5%） cysts,respectively.Three cases（4.3%） were defined as a failure.The mean size of all cysts decreased from 7.2 cm（ranging from 4 to 13） to 1.5 cm（ranging from 0 to 5;P＜0.001）.Minor complications occurred in two patients who had mild fever following aspiration and sclerotherapy.Conclusion：CT-guided sclerotherapy with ethanol concentration monitoring for hardening treatment of simple renal cyst is a simple,safe,and effective minimally invasive method.
