Abstract

PURPOSE: Percutaneous aspiration with sclerotherapy is widely used as a treatment for simple symptomatic renal cysts because percutaneous aspiration with sclerotherapy is minimally invasive and cost-effective. Sclerotherapy is usually performed in combination with aspiration due to the high recurrence rate, 30-70%, for the simple aspiration. We conducted an analysis of percutaneous aspiration with repeated sclerotherapy, and we report the results of sclerotherapy after percutaneous aspiration of simple renal cysts and we also review the results of the other previous studies.
MATERIALS AND METHODS
Between January 2001 and April 2004, the results of percutaneous aspiration with repeated sclerotherapy in 39 cases of simple renal cysts were evaluated. We evaluated the operation time, the hospital stay, the success rate, the complication rate and the follow-up period. All patients were available for follow-up over a period of 3 months by conducting ultrasound exams and computed tomography (CT) scans.
RESULTS
Complete collapse, partial collapse and recurrence of the renal cysts occurred in 24/39 (61.5%), 13/39 (33.3%), and 2/39 (5.1%) cases, respectively. The mean operative time was 50.3 minutes and the mean hospital stay was 4.5 days. The cost of two sessions of sclerotherapy was about 240,000 won and that of three sessions of sclerotherapy was about 300,000 won. The size of the cyst was not related to the rate of collapse. Any complication related to percutaneous aspiration with repeated sclerotherapy were not noted.
CONCLUSIONS
With regard for the success rate and cost-effectiveness, percutaneous aspiration with repeated sclerotherapy is considered a primary treatment for simple symptomatic renal cysts.
