Percutaneous treatment of benign renal cysts.

ABSTRACT

The percutaneous treatment of benign renal cysts has been proposed in alternative to conventional surgery. It minimizes the complication rate and assures good clinical results. In our Department, 15 patients with 16 symptomatic benign renal cysts underwent either percutaneous cyst aspiration + sclerosis (10 cases) or percutaneous resection of the cyst wall (6 cases). In the first group, all patients were relieved from symptoms, and 70% had no residual cavity. Two patients presented a secondary infection of the cyst, treated with systemic antibiotics and percutaneous drainage (1 case). In the second group, we did not observe any complication, all patients were relieved from symptoms, and only 1 cyst recurred, probably due to incomplete resection.
