To demonstrate the effectiveness and practical outcomes of percutaneous ethanol sclerotherapy in patients with symptomatic simple renal cysts. MATERIALS AND METHODS: The authors reviewed the outcomes of ten patients (eight men and two women) in the age range between 28 and 72 years (mean, 55 years) submitted to at least two procedures of percutaneous sclerotherapy for symptomatic simple renal cysts. Main presentation was refractory flank pain in all patients, seven of them with some degree of hydronephrosis because of the parapyelic localization of the cyst. The aspirated volume ranged from 20 to 1300 ml (mean, 200 ml). The mean follow-up period following the procedure was of seven months. Two patients had ultrasoud-guided sclerotherapy, and eight, computed tomography-guided sclerotherapy. The hospital stay period ranged between 24 and 72 hours. Complete success corresponded to total cyst regression, and partial success corresponded to recurrence of less than half the original cyst volume. RESULTS: Complete cyst ablation was achieved in seven patients and partial resolution in three. No complication was observed and the therapy was well tolerated by all of the patients. CONCLUSION: Percutaneous ethanol sclerotherapy of symptomatic simple renal cysts is a safe, effective and minimally invasive procedure, with results similar to the ones reported by other studies.
