Background: Simple renal cysts are rare in children and managed conservatively unless symptomatic. Objective: To demonstrate the efficacy and long-term results of single-session ethanol sclerotherapy in symptomatic simple renal cysts in children. Materials and methods: Three simple renal cysts in three children (age 1, 5 and 16 years) were included in the study. Indications for treatment were flank pain (n=1), hypertension (n=1), and increasing cyst size and urinary tract infection (n=1). The mean follow-up period was 5.5 years (range 3-7 years). The procedures were performed with the guidance of US and fluoroscopy and under IV sedation. After the cystogram, 95% ethanol with a volume of 40% of the cyst volume (but not more than 100 ml) was used as the sclerosing agent. Results: Two cysts disappeared completely, while the volume reduction was 99% for the third cyst at the end of the first year. CT demonstrated calcification of the cyst without an enhancing soft-tissue component in the third one 7 years after sclerotherapy. After the procedures, hypertension and pain resolved without any medication. There were no complications during the procedures or during follow-up. Cytological examination was unremarkable in all patients. Conclusions: Percutaneous treatment of symptomatic simple renal cysts in children with single-session ethanol sclerotherapy is a safe, effective and minimally invasive procedure. Calcification owing to sclerotherapy can be observed on follow-up.
