Purpose:
Simple renal cysts are common and can be dealt with minimally invasive procedures. We established a standard operation procecdure (SOP) on percutaneous sclerotherapy for simple renal cysts, and reviewed our results in past ten years.
Materials and Methods:
We reviewed the charts of the patients undergoing percutaneous sclerotherapy between Jan 2006 and Dec 2015. We used 95% ethanol as the sclerosing agent and followed the SOP based on a local anesthetic and ambulatory setting. Diagnosis and follow up are mainly based on ultrasonographic findings, while some of the patients underwent CT scan or MRI examinations. Results are graded as “good” for patient whose cyst volume decreased by 90% or more, “partial” for those whose cyst volume decreased by 50~89%, and “poor” for the rest. For patients with a “good” initial result but cyst volume went above 50% of baseline in any of following up imagings, a recurrence would be considered.
Results:
All punctures are successful and all patients tolerated the procedure well, There were no complications such as bleeding, wound infection, or alcohol intoxication. Our result is not inferior to other series, and recurrences are seldom.
Conclusions:
Simple renal cysts can be safely and effectively treated by percutaneous sclerosing therappy. Among various sclerosing agents, 95% ethanol is safe, efficacious, and easy to obtain, making it the first choice in our hospital. We can avoid causing pain by instilling lidocaine ahead of sclerotherapy and rinse the cyst before removing the catheter.
