The urinary system comprises the kidney, ureter, urinary bladder, and urethra. The kidney filters blood to produce urine, which contains excess water, electrolytes and waste products of the body. Urine flows from the kidney through the ureter into the bladder where it is temporarily stored.

Urinary cytology is a cost-effective, non-invasive, and readily available method for early detection and surveillance of urothelial neoplasia, with high sensitivity in detecting high-grade urothelial carcinoma (hguc). There is often wide inter-observer variability, and it is challenging to identify low-grade urothelial neoplasms (lgun).

The ureter is a muscular tube, composed of an inner longitudinal layer and an outer circular layer of smooth muscle. The lumen of the ureter is covered by transitional epithelium (also called urothelium).

The urinary system consists of the kidneys, the organ of urine production, and a set of muscular tubes that transport urine to the outside of the body. Starting from the kidneys these tubes are: ureters; the urinary bladder; the urethra. The structural unit of urine production in the kidney is a nephron. The nephron is a microscopic structure that is made of blood capillaries and a set of tubules made of kidney epithelium.
