Abstract

Thirty-eight benign renal cysts in 35 patients were treated with or without 99% ethanol during diagnostic aspiration under ultrasonic guidance. All were followed by ultrasound from 3 to 59 months. There were twelve (80% ) recurrences in simple aspiration group. Two cases ( 6.25% ) were recurred in ethanol instillation group. All of the five symptomatic patients were relieved of subjective symptoms such as flank pain after alcohol instillation. Minor complications of local pain and temperature elevation were no more prevalent than with simple aspiration alone. There was no major complication. In conclusion, it is reasonable to treat and prevent of renal cyst by ablation of the cyst with alcohol at the same time as diagnostic procedure.
