PURPOSE: To perform a prospective randomized study to evaluate aspiration and sclerotherapy vs. laparoscopic deroofing in the management of symptomatic simple renal cysts. PATIENTS AND METHODS: Forty patients with symptomatic simple renal cysts were randomized to treatment either by ultrasonography-guided aspiration and sclerotherapy (group A-20 patients) or by laparoscopic deroofing (group B-20 patients). Two patients in group A and one patient in group B had a parapelvic cyst. Patients were evaluated by urine analysis, serum creatinine level, coagulation profile, ultrasonography, and CT urography. In group A patients, after aspiration, 1% polidocanol in a volume equivalent to 10% of cyst volume was instilled. In group B patients, laparoscopic deroofing was performed. All patients were followed up by ultrasonography up to 1 year after treatment. RESULTS: In group A, aspiration and sclerotherapy was performed on an outpatient basis, and none of the patients needed postoperative analgesia. Eighteen of 20 patients had complete regression; two of these had parapelvic cyst. Partial regression with relief of pain was noted in one patient, whereas treatment failed in one patient. None of the patients had any significant complication and none required analgesia. All the patients were discharged two hours after the procedure. In group B, laparoscopic deroofing was successfully performed in 19 of 20 patients. Laparoscopic deroofing could not be performed in one patient with parapelvic cyst because of failure of access. The mean analgesic requirement was 285 ± 57.98 (200-400) mg tramadol, and average hospital stay was 2.1 ± 0.32 (2-3) days. CONCLUSION:Percutaneous aspiration and sclerotherapy with polidocanol is an effective, safe, and minimally invasive therapeutic option for symptomatic simple renal cysts, with equal efficacy and lower morbidity and hospital stay in comparison with laparoscopic deroofing.
