Clinical InformationClinical

  • Mesangial Proliferative Glomerulonephritis

    a focal inflammation of glomeruli secondary to mesangial cell proliferation and matrix deposition within the mesangium.

  • Focal and Segmental Proliferative Glomerulonephritis

    glomerulonephritis characterized by proliferation of endothelial or mesangial cells, affecting the glomeruli in a focal and segmental pattern.

Patient EducationClinical

Kidney Diseases

You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters.
