ABSTRACT
Purpose:
The incidence of renal cell carcinoma has been steadily increasing over the past two decades, raising the need for minimally invasive approaches. We sought to present the methodology of the percutaneous cryoablation (PCA) procedure developed based on one year of experience with 81 PCA procedures.
Material and methods:
The percutaneous cryoablation programme at Wroclaw Medical University Hospital has been successfully operating for a year. During this period, patients who were ineligible for partial nephrectomy either because of numerous comorbidities or strong preference against surgery were treated with PCA. Each procedure was conducted with the close cooperation of an interventional radiologist and a urologist.
Results:
Over the past year, 81 procedures in 74 individuals have been performed and thoroughly analysed. The mean and median effective radiation doses were 12.57 mSv and 10.76 mSv, respectively. Comprehensive details of our workflow are described within the body of the manuscript.
Conclusions:
Percutaneous cryoablation is a technically effective treatment approach for carefully selected individuals with small renal masses. However, starting a PCA programme from scratch necessitates creation of detailed protocols, as well as close interventional radiologist and urologist cooperation. This review outlines the established workflow and shares insights gained from one year of experience with percutaneous cryoablation.
