Urology RENAL Nephrometry

RENAL Nephrometry Score is an app to help medical practitioner to quantifies the salient characteristics of renal mass anatomy in an objective and reproducible manner. RENAL Nephrometry scoring system is based on the 5 most reproducible features that characterize the anatomy of a solid renal mass: (R)adius, (E)xophytic/endophytic properties of the tumor, (N)earness of the tumor to the collecting system or renal sinus, (A)nterior (a)/posterior (p) descriptor and the (L)ocation relative to the polar line. All components except for the (A) descriptor are scored on a 1, 2, or 3-point scale. The (A) describes the principal mass location to the coronal plane of the kidney.

In RENAL Nephrometry Score app, the total nephrometry scores will be counted and classified. Masses with Nephrometry Scores totaling 4-6 were considered low complexity for resection, 7-9 were considered moderate complexity, and 10-12 were considered high complexity. Higher complexity is associated with higher major complication rates if partial nephrectomy is performed for those masses. We hope that RENAL Nephrometry Score will help medical practitioner, especially urologist for surgical decision-making of the renal masses.
