Renal cysts: treatment with alcohol.

Abstract

Benign renal cysts (34) in 29 patients were treated with 95% ethanol during diagnostic aspiration with a 4.6 French pigtail catheter. All were followed by ultrasound from 3-30 mo. There was 1 recurrence at 3 mo. Minor complications of hematuria and temperature elevation were no more prevalent than with diagnostic aspiration alone. There were no major complications.
