ABSTRACT

PURPOSE:

Percutaneous aspiration with sclerotherapy has been widely used for the treatment of symptomatic or large simple renal cysts. Ethanol has been most commonly used as a sclerosing agent; however, a temporary percutaneous nephrostomy for multiple ethanol injections is necessary to achieve a low recurrence rate. Thus, we used OK-432 as a new sclerosing agent without a temporary percutaneous nephrostomy for multiple injections, and also compared our results with the results of previous studies. MATERIALS AND METHDOS Between October 2005 and April 2006, 50 patients (63 simple renal cysts) who underwent percutaneous OK-432 sclerotherapy for simple renal cysts were evaluated. The simple renal cysts were aspirated under ultrasonography and fluoroscopy, after which OK-432 was injected into the cyst. Follow-up was performed with ultrasonography or CT scan after 3 months. Regression of the renal cyst or a >70% reduction in size with no symptoms was considered a treatment success.

RESULTS:

Among 63 renal cysts in 50 patients, complete regression occurred in 17(27.0%). Greater than a 90% reduction in size occurred in 8(12.7%), a 80-90% reduction in size occurred in 21(33.3%), and a 70-80% reduction in size occurred in 15(23.8%); a <70% reduction in size occurred in 2 (3%). The overall efficacies of success were 96.8%. After the procedure, there were only some minor complications, such as mild fever, local pain, and liver function test elevation that subsided with symptomatic treatment.

CONCLUSIONS:

Percutaneous OK-432 sclerotherapy is simple, safe, and effective and can be an alternative first-line therapy of simple renal cysts.
