First Prize (Tie): Laparoscopic Renal Cryoablation: Efficacy and Complications for Larger Renal Masses

Abstract

Renal cryoablation of renal cortical neoplasms smaller than 3.0 cm is effective and safe. Our initial experience, however, demonstrates that cryoablation of larger renal masses may be associated with increased morbidity.

R.E.N.A.L. (Radius, Exophytic/Endophytic, Nearness to Collecting System or Sinus, Anterior/Posterior, and Location Relative to Polar Lines) Nephrometry Score Predicts Early Tumor Recurrence and Complications after Percutaneous Ablative Therapies for Renal Cell Carcinoma: A 5-Year Experience

“…A.L. nephrometry score of Z9 is an independent predictor of complications after cryoablation; however, multivariate analyses suggest that this is associated with tumor size and central location rather than the score itself (41)(42)(43).…”

R.E.N.A.L. Nephrometry Score Accurately Predicts Complications Following Laparoscopic Renal Cryoablation

“…As per the findings of Lehman et al, our current practice preference is to use extirpative surgical options in patients with tumors larger than 3.5 cm. 19 However, this strict size cutoff may be compromised in older patients with significant comorbidities in whom renal preservation is of paramount importance.…”

Cryoablation for Small Renal Masses: Selection Criteria, Complications, and Functional and Oncologic Results

“…In addition, repositioning of the patient may cause the adjacent bowel to shift away from the tumor. Larger renal tumors (!3 cm) may also be treated with CA, taking advantage of the synergy of multiple cryoprobes [46,52].…”
