[Percutaneous sclerosing of kidney cysts with alcohol]

Abstract

Symptomatic benign renal cysts in 23 patients were obliterated by ultrasound-guided puncture and instillation of sterile 95% ethanol. In no case did complications occur. In 5 cases the cysts recurred after an average of 3 months; the primary size (diameter) was more than 10 cm in all of these. This simple technique seems to be a suitable treatment option for smaller cysts up to 10 cm because of its low complication rate and because no hospital admission is required.
