A preoperative prognostic nomogram for solid enhancing renal tumors 7 cm or less amenable to partial nephrectomy.

Abstract

Small renal masses are increasing in incidence. Most tumors 7 cm or less are treated with radical or partial nephrectomy but clinicians are increasingly relying on ablative therapies and observation for some small renal masses. We present novel nomograms that predict the likelihood of benign, likely indolent or potentially aggressive pathological findings based only on readily identifiable preoperative factors.
