Intermediate-term outcomes after renal cryoablation: results of a multi-institutional study.

Purpose: To present intermediate-term oncologic efficacy of cryoablation (CA) for the treatment of patients with small renal masses in a multi-institution multisurgeon cohort.

Patients And Methods: We retrospectively reviewed billing records and tumor registries, identifying 116 renal tumors in 116 patients treated with CA by six surgeons at four institutions. Patient age, sex, tumor size, RENAL nephrometry score, complications, and recurrences were recorded.
