What is the cause of high phosphorus epithelial cells in urine test

Squamous cell proliferation is often seen in inflammation. Urine shows epithelial cells throughout the urinary system from the renal tract to the urethra, including tubular epithelial cells, transitional epithelial cells, and stratified squamous cells. Among them, stratified flat cells are squamous epithelial cells. These cells are large and flat polygonal in morphology, with small, round or oval nuclei. These cells often come from the anterior urethra. Female urethra is sometimes mixed with stratified flat epithelial cells from vagina. When urine is displayed in large numbers or exfoliated and accompanied by white blood cells and pus cells, it is seen in urinary system infection, especially urethritis.
