[Sclerotherapy with Betadine for simple cysts of the kidney. Apropos of 7 cases].

The authors report on 7 cases of benign, symptomatic renal cysts treated by percutaneous sclerosis using Betadine solution. The mean size of the cysts was 8 cm and we obtained progressive collapse of all of them. This technique was a simple and effective methode with good results. Indeed, 85% of the cysts disappeard, and only one patient retained a small asymptomatic residual cavity.
