Percutaneous unroofing of renal cysts

Renal cyst is a common renal disease. It rarely produces symptoms, and thus rarely requires treatment. Treatment becomes necessary when the cyst is symptomatic or complicated. The possible approach includes surgical unroofing or cyst puncture without or with intracystic injection of sclerosing agents. This is a report on the percutaneous unroofing for the treatment of symptomatic or complicated renal cysts.
