The fundus is the base or bottom part of the urinary bladder, opposite the opening called the trigone. It’s the area where the bladder expands to store urine before it is expelled from the body.
Pathophysiology
Structure
- Urinary Bladder Anatomy: The bladder is a muscular sac that stores urine. It consists of three layers:
- Mucosa: The inner lining.
- Muscularis: The middle muscular layer.
- Serosa: The outer layer.
- Fundus Specifics: The fundus is the posterior part, less involved in urine expulsion but crucial for bladder capacity.
Blood Supply
- Arterial Supply: Primarily from the superior and inferior vesical arteries.
- Venous Drainage: Drains into the internal iliac veins.
- Lymphatic Drainage: To pelvic lymph nodes.
Nerve Supply
- Autonomic Nervous System:
- Sympathetic: Controls bladder relaxation and urine storage.
- Parasympathetic: Facilitates bladder contraction for urination.
- Somatic Nerves: Provide sensory information and control external sphincters.
Types of Fundus Bladder Diseases
- Cystitis: Inflammation of the bladder.
- Bladder Cancer: Malignant growth in bladder tissues.
- Bladder Stones: Hard mineral deposits in the bladder.
- Bladder Diverticula: Pouches protruding from the bladder wall.
