[Study on the sclerosing agent for the treatment of simple renal cysts].
BACKGROUND
The objective of this study is to evaluate the sclerosing agents for simple renal cysts.


METHODS
Thirty-three renal cysts of 30 patients were treated by injection of sclerosing agents with the guidance of ultrasonography. Among them, 22 were treated with ethanol, and 11 with minocycline-hydrochloride (MINO).


RESULTS
Clinical efficacy rates and volume reduction rates in each treatment group of ethanol or MINO, were 100% and 90.9%, and 91.2 +/- 13.1% (mean +/- SD) and 83.2 +/- 28.5%, respectively. Although several complications including pain and intoxication were observed in ethanol (47.4%), no complications were observed in MINO.


CONCLUSIONS
The instillation of MINO into renal cysts is an effective, safe and simple treatment. It is thought that it can be the first choice of treatment for simple renal cysts.
