Due to its diagnostic accuracy as well as safe and accurate puncture technique CT can be used advantageously for percutaneous sclerosing therapy of renal cysts. CT-guided sclerosing therapy with pantopaque emulsions was carried out in 100 patients on an outpatient basis with altogether 107 solitary renal cysts. There were indications in all cases. Continuous follow-up of cyst involution in 96 patients with 103 cysts pointed out a reliable sclerosing effect in 95.1% of them. Major complications were neither registered in the puncture technique nor in the late urographic examinations.
