Abstract:
PURPOSE: Recently the percutaneous aspiration with sclerotherapy of the simple renal cyst are being widely used because of the high success rate and the low morbidity. However, studies concerning the long term result of this technique have been rarely reported. Thus, we performed this study to evaluate the long term results of this technique. MATERIALS AND METHODS: We evaluated the long term result of the treatment in 20 cases of simple renal cysts from July 1993 to July 1998. The symptoms associated with simple renal cysts were: none(55%), pain(35%) and palpable mass(10%). The simple renal cysts were treated with percutaneous aspiration and injection of 99% ethanol in 15 cases or percutaneous aspiration and injection of 10% tetracycline solution in 5 cases. All were followed by ultrasound from 18 to 58 months(mean 32.7 months). RESULTS: Complete collapse, partial collapse and recurrence of the renal cysts were 5/15(33.3%), 7/15(46.6%), 3/15(20%) in 99% ethanol group and 3/5(60%), 1/5(20%), 1/5(20%) in 10% tetracycline solution group, respectively. Overall efficacies were 80% in both groups. Furthermore, all recurrences occurred within the first year of follow up period in both groups. CONCLUSIONS: Therefore, percutaneous aspiration with sclerotherapy using 99% ethanol or 10% tetracycline solution seem to be an effective way to prevent re-accumulation of cystic fluid. It also proved to have a positive long term result concerning the relapse of the simple renal cyst.
