The increase in the NFP would result in an increase in the GFR.
NFP stands for Net Filtration Pressure and GFR stands for Glomerular Filtration Rate. The two quantities are associated with the process of blood filtration and urination process in the kidney. When the blood vessels leading to the kidney expand and the blood vessels leading out of the kidney shrink, it leads to the build up of the GFR in glomerulus. This leads to the increase in the process of the blood filtration and thus increases the NFP.
