Background
The commonest kidney malignancy is renal cell carcinoma (90% of all renal tumors) [1],
which consist in different subtypes with specific histopathological and genetic characteristics.
The clear cell carcinoma is the most common histologic subtype,
accounting for 70%–80% of all RCCs [1].
With the widespread use of ultrasound and CT,
most RCCs are now diagnosed incidentally during imaging performed for other reasons,
leading to an earlier diagnosis [2].
Consequently,
the tumors have smaller sizes and are at lower stages at diagnosis.
These smaller lesions raise problems not only in terms of imaging characterization but also about treatment options.
Nowadays the decision is no more between a wait-and-see approach or total nephrectomy,
but instead between a myriad of therapeutic options,
from nephron-sparing surgery to tumor ablation techniques [3].
With that in mind it was necessary to go beyond the TNM staging system and creating new scoring systems that helps planning the best treatment approach.
Among them are the R.E.N.A.L.
nephrometry schemes,
the C–Index scoring,
the P.A.D.U.A.
classification and the A.B.L.A.T.E.
algorithm.
