Percutaneous Cryoablation Versus Partial Nephrectomy for T1b Renal Tumor

A Prospective, Non-randomized, in Parallel Groups Study Evaluating the Efficacy and Safety of Percutaneous Cryoablation and Partial Nephrectomy in Localized T1b Renal Tumor

The aim of our study is to assess the long-term oncological and functional outcomes of cryoablation for T1b renal tumors, as well as such important parameters as the patient's quality of life after treatment, and to compare the results with those after partial nephrectomy.

Inclusion Criteria:

•CT-confirmed renal mass > 4 to 7 cm (T1b)

Exclusion Criteria:

• Multiple renal tumors;
• Recurrence of renal tumor;
• Intolerance to iodine-containing contrast agents;
• Pregnancy;
• Patients with Bosniak 4 cysts
• Presence of other oncological diseases;
• Impossibility of organ-preserving treatment due to the proximity of the tumor to the vessels or the calyx-pelvic system
• Absence of malignant pathology based on prior biopsy.
