Abstract

PURPOSE
To evaluate the usefullness of repeated alcohol sclerotherapy for two days through the percutaneous catheter in the treatment of renal cyst.
MATERIALS AND METHODS
Repeated sclerotherapies using absolute ethanol(99.9%) were parformed on 20 renal cysts in 18 patients through the indwelling catheter. The cyst volume ranged from 50 ml to 1000ml(mean, 300ml). Under the ultrasound- or CT-guidance, 6F catheter was inserted into the cyst percutaneously. After aspirating the fluid in the cyst, absolute ethanol was injected. While maintaining the catheter for 16-20 hours, at least 3 times of sclerotherapies performed with total procedure time of 30-60 minutes. Follow-up sonography was performed to evaluate the recurrence or collapse of the cysts at 1 and 3 months after the procedure.
RESULTS
Among 20 renal cysts, 2 cases were recurred on 1 month follow-up sonography(10%). However, the volumes of recurred cysts were decreased to 40% and 10%, respectively. There was no immediate or delayed complication after sclerotherapy. DISCUSSION: Repeated sclerotherapy for 2 days using absolute ethanol through the percutaneous catheter insertion is a useful method of treatment for renal cyst.
