Abstract:
PURPOSE: Sclerotherapy is performed additionally to improve the outcome of aspiration in simple renal cyst. Ethanol has been used most commonly as a sclerosing agent, however, drainage is necessary which complicates the procedure. For this reason, we used minocycline HCl as a sclerosing agent without need to be drained and evaluated the results. MATERIALS AND METHODS: From June 1990 to May 1999, 140 patients who underwent percutaneous minocycline HCl sclerotherapy for simple renal cyst were evaluated. Among them, 10 patients were missed during follow-up and 7 patients had bilateral simple renal cysts. The simple renal cysts were aspirated under ultrasonography, and then minocycline HCl 100mg mixed with 5ml normal saline was injected into the cyst per 50ml of aspirated cyst fluid. The follow-up ultrasonography was performed at posttreatment 3, 6 and 12 months. The recurred cases were retreated with same procedure. RESULTS: Among 137 renal cysts of 130 patients who could be followed up, 70 renal cysts (51.1%) were totally collapsed and 53 renal cysts (38.7%) showed a 50% or more decrease in cyst volume after first treatment. All 14 persistent renal cysts (10.2%) showed a 50% or more decrease in cyst volume after second or third treatment. Catheterization for drainage of the sclerosing agent was not needed. There were only some minor complications such as nausea, vomitting and local pain that subsided within one day with only symptomatic treatment. CONCLUSIONS: These results shows that percutaneous minocycline HCl sclerotherapy is simple, safe and effective and can be a alternative first line therapy of simple renal cyst.
