Renal ureter cancer is a type of cancer that develops in the ureter, the tube that carries urine from the kidneys to the bladder. This cancer can also be related to the kidneys since they are closely connected.
Pathophysiology
1. Structure:
- The ureters are thin tubes lined with a layer of cells called the urothelium. This lining is important for the ureter’s function and can be where cancer starts.
- The ureters connect to the kidneys at the top and to the bladder at the bottom.
2. Blood Supply:
- The blood supply to the ureters comes mainly from the renal arteries, which branch off from the aorta, the main artery in the body.
- Ureteral arteries also supply blood to the ureters and are essential for their health.
3. Nerve Supply:
- The ureters are controlled by nerves that help them contract and move urine. These nerves come from the sympathetic and parasympathetic nervous systems, which control involuntary body functions.
Types of Renal Ureter Cancer
- Urothelial Carcinoma: The most common type, starting in the urothelium.
- Squamous Cell Carcinoma: This arises from squamous cells, usually due to irritation or inflammation.
- Adenocarcinoma: Originates from glandular cells and is rarer in the ureter.
- Small Cell Carcinoma: A rare type that is aggressive and often associated with smoking.
Causes of Renal Ureter Cancer
- Smoking: Increases the risk significantly.
- Chemical Exposure: Contact with certain chemicals, like aniline dyes.
- Chronic Infections: Long-term urinary tract infections can lead to cancer.
