The Diameter-Axial-Polar Nephrometry Score is associated with various outcomes in patients with a renal tumor.
Patient selection: renal tumor
Parameters:
(1) diameter of tumor in cm
(2) axial distance from horizontal center cm
(3) polar distance from coronal center in cm
Parameter
Finding
Points
diameter of the tumor
< 2.4 cm
1
2.4 to 4.4 cm
2
> 4.4 cm
3
axial distance
overlap with center
<= 1.5 cm
> 1.5 cm
polar distance
> 2 cm
<= 2 cm
overlap with central line
total score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 3
• maximum score: 9
• The higher the score the greater the surgical complexity and greater loss of long-term renal function.
• A lower score can undergo partial nephrectomy.
