Purpose:We observed and compared the therapeutic effects of CO_2 and dehy- drated ethanol as sclerosing agent,in percutaneous interventional methods for treatment of hepatic and renal cysts,Materials and methods:Twenty-two simple cysts,14 in livers,8 in kidneys,af- ter percutaneous puncture and aspiration,we instilled CO_2 or dehydrated ethanol into the cysts once, twice or thrice with followed-up for 2 to 29 months,Results:All the 22 cysts in 22 patients were better after treatment especially of them,including 8 of 12 cases(66.7%)treated with dehydrated ethanol only once.The maximum diameters of 8 renal cysts(8/8,100%)after one treatment re- duced to less than 2cm in the follow-up,comparing with only 5 of 14 hepatic cysts(5/14,35. 7%).Conclusion:1)Pereutaneous interventional method by guidance of ultrasound is safe and ef- fective in simple hepatic or renal cyst treatment.2)CO_2 is similar to dehydrated ethanol as a scleros- ing agent.3)The therapeutic effect of simple renal cyst is better than that of hepetic cyst.
