Calyceal Cancer

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

1. Renal Cell Carcinoma? (RCC): The most common type of kidney cancer, which can affect the calyces.
2. Transitional Cell Carcinoma: Often starts in the renal pelvis? but can invade calyceal structures.
3. Sarcoma?: A rare type of cancer that can occur in the kidney’s soft tissues.
4. Lymphoma?: Cancer that begins in the lymphatic system and can affect the kidneys.
