Calyceal cancer is a type of cancer that occurs in the calyces, which are the cup-shaped structures in the kidney. These structures help collect urine from the kidney and direct it to the renal pelvis, where it then flows into the ureter.
Pathophysiology
Structure:
- Kidneys: Two bean-shaped organs that filter blood and produce urine.
- Calyces: The areas in the kidney where urine collects.
Blood Supply:
- The renal arteries supply blood to the kidneys. Cancer can disrupt this blood flow, affecting kidney function.
Nerve Supply:
- The kidneys receive nerve supply from the autonomic nervous system, which can influence kidney function and pain perception.
Types of Calyceal Cancer
- Renal Cell Carcinoma (RCC): The most common type of kidney cancer, which can affect the calyces.
- Transitional Cell Carcinoma: Often starts in the renal pelvis but can invade calyceal structures.
- Sarcoma: A rare type of cancer that can occur in the kidney’s soft tissues.
- Lymphoma: Cancer that begins in the lymphatic system and can affect the kidneys.
Causes of Calyceal Cancer
