Renal Pelvis Masses

Pathophysiology

Structure

• Renal Pelvis: The central part of the kidney where urine collects.
• Kidneys: Bean-shaped organs that filter blood and produce urine.
• Ureters: Tubes that carry urine from the kidneys to the bladder.

Blood Supply

• The renal arteries supply blood to the kidneys, branching from the abdominal aorta.
• Venous blood drains through the renal veins into the inferior vena cava.

Nerve Supply

• The kidneys are innervated by the autonomic nervous system, which helps regulate their function.

Types of Renal Pelvis Masses

1. Benign Tumors: Non-cancerous growths like angiomyolipoma.
2. Malignant Tumors: Cancerous growths like transitional cell carcinoma.
3. Cysts: Fluid-filled sacs that may cause issues if large.
4. Infections: Such as pyelonephritis leading to swelling or abscesses.
5. Fibromas: Fibrous tissue growths in the renal pelvis.
