Abstract

Urine is an acellular liquid product of renal excretory function. As liquid passes through the renal tubules, renal pelvis, ureter, urinary bladder, and urethra, it picks up desquamating cells derived from the epithelia of these organs. Inflammatory cells, erythrocytes and macrophages are frequently seen. Voided urine has an acid pH and a high content of urea and other organic components; therefore it is not isotonic. Consequently, urine is not a hospitable medium for desquamated cells, which are often poorly preserved and sometimes difficult to access microscopically.
