PERCUTANEOUS RESECTION OF RENAL CYSTS - A LONG-TERM FOLLOW-UP

Renal cysts are incidentally seen in ultrasonographic studies and are usually asymptomatic. However, some patients still present with symptoms due to a renal cyst. Various techniques have been reported for the treatment of renal cysts. Percutaneous resection of symptomatic cysts has been performed at our hospital since 1984. We investigated the long-term results of 10 patients who underwent percutaneous resection of renal cysts after a median followup of 45.7 months regarding the recurrence rate, late sequelae and clinical efficiency. Successful resection with no evidence of renal cysts was obtained in 50% of the patients at followup, a recurrence in 30% and residual cysts with up to a 45% decrease in size in 20%. All patients were cured of the symptoms and none had any late complications. We believe that percutaneous resection of renal cysts represents a valuable technique for the treatment of patients with symptomatic renal cysts. Neither postoperative nor late complications occurred after a median followup of 45.7 months.
