Cancer of the ureters is known as ureteral cancer. It is usually due to cancer of the urothelium, the cells that line the surface of the ureters. Urothelial cancer is more common after the age of 40, and more common in men than women; [18] other risk factors include smoking and exposure to dyes such as aromatic amines and aldehydes. [18]
Facet cells (also known as umbrella cells, [1] capping cells, superficial urotheliocytes) are a type of cells located in the renal pelvis, the ureters, and the urethra. Umbrella cells form the outermost layer of the urothelium, which is a special type of epithelium found in the renal pelvis, the ureters, and the urethra. Umbrella cells are ...

The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra.The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.
The typical mammalian kidney consists of a renal capsule, a peripheral cortex, an internal medulla, one or more renal calyces, and a renal pelvis. [7] Although the calyces or renal pelvis may be absent in some species. [7] The medulla is made up of one or more renal pyramids, [8] forming papillae with their innermost parts. [9]
Urology addresses diseases of kidney (and urinary tract) anatomy: these include cancer, renal cysts, kidney stones and ureteral stones, and urinary tract obstruction. [ 7 ] The word “ renal ” is an adjective meaning “relating to the kidneys”, and its roots are French or late Latin.
The foot processes have an actin-based cytoskeleton. [6] Podocytes are found lining the Bowman's capsules in the nephrons of the kidney. The pedicels or foot processes wrap around the glomerular capillaries to form the filtration slits. [7] The pedicels increase the surface area of the cells enabling efficient ultrafiltration. [8]
Sample of human urine. Urine is a liquid by-product of metabolism in humans and in many other animals. In placental mammals, urine flows from the kidneys through the ureters to the urinary bladder and exits the urethra through the penis or vulva during urination.
