Which element corresponds to transitional cells in urine?

Transitional epithelial cells are urothelial cells that line the inner surfaces of the urinary tract—from the renal pelvis and ureters down to part of the urethra. In a urine sample, detecting these cells means you’re seeing cells shed from this lining. They are distinct from red blood cells, which indicate bleeding; white blood cells, which point to infection or inflammation; and squamous epithelial cells, which often come from contamination of the sample. So the element that corresponds to transitional cells in urine is the urothelial (transitional) cell itself. Small numbers can be normal, but more may suggest urinary tract irritation or pathology.
