Renal Pelvis Cancer

Renal pelvis cancer is a type of cancer that affects the renal pelvis, the area where urine collects before it moves to the bladder. This article will cover the pathophysiology, types, causes, symptoms, diagnostic tests, treatments, and preventive measures associated with renal pelvis cancer.

Renal pelvis cancer starts in the cells lining the renal pelvis, which is part of the kidney. This cancer is often grouped with other urinary tract cancers, especially those affecting the bladder and ureters.

Pathophysiology

Structure

The kidneys are bean-shaped organs located on either side of the spine. They filter blood to produce urine. The renal pelvis is the central part of the kidney, funneling urine from the kidney to the ureter, which leads to the bladder.

Blood Supply

The kidneys receive blood from the renal arteries, which branch off from the abdominal aorta. Blood is filtered through the kidneys, and waste is removed in the form of urine.

Nerve Supply

The kidneys are innervated by the autonomic nervous system, which controls involuntary functions. This nerve supply helps regulate kidney functions, including blood flow and urine production.

Types of Renal Pelvis Cancer

1. Urothelial Carcinoma: The most common type, originating from the cells lining the renal pelvis.
2. Transitional Cell Carcinoma: A subtype of urothelial carcinoma that can also affect the bladder.
3. Squamous Cell Carcinoma: Rare type that may develop in response to chronic irritation or inflammation.
4. Adenocarcinoma: Arises from glandular tissue, though it’s very rare in the renal pelvis.
5. Small Cell Carcinoma: An aggressive form that is also very rare.

Causes of Renal Pelvis Cancer

While the exact cause of renal pelvis cancer is not fully understood, several factors can contribute:

1. Smoking: Tobacco use increases the risk of urinary tract cancers.
2. Chronic Irritation: Conditions like kidney stones or urinary tract infections can lead to cell changes.
3. Chemical Exposure: Certain industrial chemicals are linked to bladder and kidney cancers.
4. Genetics: A family history of kidney or bladder cancer can increase risk.
5. Age: Risk increases with age, especially in those over 60.
6. Gender: Men are more likely than women to develop this cancer.
7. Obesity: Higher body weight is associated with various cancers.
8. Diabetes: Diabetics may have a higher risk of kidney and bladder cancers.
9. Radiation Exposure: Previous radiation therapy can increase the risk.
10. HIV/AIDS: People with weakened immune systems are at greater risk.
11. Cystitis: Chronic bladder inflammation can increase risk.
12. Hydration Levels: Low fluid intake may lead to concentrated urine and irritate the bladder and renal pelvis.
13. Diet: High consumption of processed meats has been linked to increased cancer risk.
14. Hereditary Syndromes: Conditions like Lynch syndrome increase the risk of various cancers.
15. Urinary Tract Abnormalities: Congenital issues can increase cancer risk.
