A Painless and Time-Saving Modified Technique for Simple Renal Cyst Treatment with Single-session Ethanol Sclerotherapy.

Percutaneous puncture ethanol sclerotherapy is a simple, effective, minimally invasive, and inexpensive procedure to manage symptomatic simple renal cysts. We modified specific technical aspects to balance certain potential intraprocedural factors for ensuring minimal procedural pain and duration as well as maximal clinical therapeutic effects and evaluated the safety and efficacy of this modified technique. A total of 84 eligible patients underwent computed tomography-guided single-session ethanol sclerotherapy using the conventional (group A) or modified (group B) technique.
