A medical team at the Mayo Clinic has determined that with sonographic guidance, a percutaneous transhepatic approach can be used for radiofrequency ablation treatment of renal tumors, especially for masses in the right kidney, where the overlying bowel or inflated lung can make treatment difficult. "Using real-time ultrasound guidance, the proceduralist can account for respiratory motion, allowing precise applicator placement," the team wrote. Their paper was published in the journal Cardiovascular and Interventional Radiology.
