Understanding the workings and usefulness of R.E.N.A.L.
a cross-sectional imaging based systematic approach to help characterize renal masses and its complexity using images from (multiphasic contrast-enhanced) CT or MRI (preferably with,
possibly without contrast).
Renal tumors are relatively common findings in daily clinical practice,
either incidentally discovered in cross sectional studies performed for other purposes or when investigating related signs and symptoms such as hematuria or flank pain.
Recent literature suggests a growing incidence which can,
at least in part,
be explained by technological advances and widespread availability of imaging studies.
Also noted is a tendency for increased detection of smaller tumors,
easy to understand in...
Findings and procedure details
first developed by Kutikov and Uzzo in 2009,
is an acronym that encompasses 5 major anatomic considerations which determine surgical complexity associated with Nephron Sparing Surgery: “R”adius (actually,
diameter in cm) is an obvious choice and illustrates the size of the tumor measured in cm at its widest diameter,
with categories dividing tumors smaller than 4cm,
between 4 and 7cm and over 7cm into 1,
2 or 3 points respectively (Fig.
Some studies show this to be the parameter...
Nephrometry Score is a useful scoring system that combines five of the most important tumor anatomic considerations and aims to help urologists plan surgical procedures according to a standardized approach,
attempting to make surgical options less subjective and offering up a solid base for future comparative studies.
Given the system’s reliance on cross-sectional imaging,
Radiologists are placed in a prime position to help guide and optimize patient care in order to strive for the...
