RENAL Nephrometry Score
R.E.N.A.L. nephrometry score quantifying the anatomical complexity of a renal mass for surgical planning. The A component is a descriptive suffix (no points).
Result
4a
Sum of R + E + N + L, with the “a” anterior/posterior suffix.
Formula
Score = R + E + N + L (each 1–3). A is a descriptive suffix (a/p/x).
Disclaimer
A hilar (h) suffix is added when the mass abuts the main renal artery/vein. The score aids surgical planning but does not by itself dictate management.
