Percutaneous cryoablation of renal tumours: outcomes from 171 tumours in 147 patients.

Objective: To evaluate the technical and oncological efficacy of an image-guided cryoablation programme for renal tumours.

Patients And Methods: A prospective analysis of technical and radiological outcomes was undertaken after treatment of 171 consecutive tumours in 147 patients. Oncological efficacy in a subset of 125 tumours in 104 patients with >6 months' radiological follow-up and a further subset of 62 patients with solitary, biopsy-proven renal carcinoma was also analysed.
