Is there such thing called CHRONIC FOCAL Glomerulonephritis?

Chronic focal glomerulonephritis is not a standard term used in medical literature. Glomerulonephritis refers to inflammation of the glomeruli in the kidneys, and it can be classified as acute or chronic based on the duration and progression of the disease. "Focal" generally describes a condition affecting only a portion of the glomeruli, but when combined with "chronic," it may not be commonly recognized. Instead, specific types of chronic glomerulonephritis, such as focal segmental glomerulosclerosis (FSGS), are more widely discussed.
