Percutaneous Cryoablation Versus Partial Nephrectomy for T1b Renal Tumor
Percutaneous Cryoablation Versus Partial Nephrectomy for 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.
