The nephritic syndrome is a clinical syndrome that presents as hematuria, elevated blood pressure, decreased urine output, and edema. The major underlying pathology is inflammation of the glomerulus that results in nephritic syndrome. It causes a sudden onset of the appearance of red blood cell (RBC) casts and blood cells, a variable amount of proteinuria, and white blood cells in the urine. The primary pathology can be in the kidney, or it can be a consequence of systemic disorders.
