Kutikov A, Uzzo RG. The R.E.N.A.L. nephrometry score. J Urol. DOI: 10.1016/j.juro.2009.05.035. PMID: 19616235. R is 1 if ≤4 cm, 2 if >4 to <7 cm, and 3 if ≥7 cm. E and L are the published 1–3 categories. N is 1 if ≥7 mm, 2 if >4 to <7 mm, and 3 if ≤4 mm. The sum is R+E+N+L (4–12). The anterior/posterior descriptor is recorded and is not added. (2009)
