Abstract
Cryoablation is emerging as an accepted treatment for small renal tumors. Percutaneous placement of cryoprobes using ultrasound guidance is an attractive option for patients with tumors easily seen with transabdominal ultrasonography; however, the placement of probes using hand-held devices is technically challenging. To improve the accuracy and ease of cryoprobe placement during percutaneous renal cryoablation, we describe the novel application of the CIVCO Assist™ positioning arm system during these complex procedures.
