Minimal invasive thermal ablative techniques are emerging as a viable option for patients who are not candidates for open, laparoscopic or robotic-assisted partial nephrectomy
. Cryoablation is a low risk alternative with good oncologic outcomes. We present our initial experience with cryoablation for small renal masses using the laparoscopic approach.
Patients and Methods:
We prospectively collected the perioperative data of patients undergone renal cryoablation at our institution. From May/2009 to January/2011, 41 patients with incidental small renal mass were submitted to laparoscopic cryoablation
The mean patient age was 58.8 years. The mean operative time was 115.4 ± 60.3 min and no patient needed blood transfusion. The mean of size tumors was 2.8 cm (1-5 cm). Intraoperative biopsies showed 27 (65%) malignant tumors, 5 (12%) oncocytomas, two (6%) angiomyolipomas 7 (17%) inconclusive. With a mean follow-up of 16 months (12-21), there were no significant differences between creatinine
, estimated glomerular filtration rate and hemoglobin level before and after the procedure. There was no open conversion, kidney loss, urinary fistula, dialysis
requirement or re-operations.
Conclusion: Laparoscopic renal cryoablation is safe, with low complication rate and short learning curve.
