A fundus of urinary bladder hematoma is a medical condition characterized by the accumulation of blood in the fundus, the base or bottom part of the bladder. This condition can result from various causes and may present with multiple symptoms. Understanding its pathophysiology, types, causes, symptoms, diagnostic methods, treatments, prevention strategies, and when to seek medical help is crucial for effective management and recovery.
A hematoma is a collection of blood outside blood vessels, usually caused by an injury to the wall of a blood vessel, prompting blood to leak into surrounding tissues. When this occurs in the fundus of the urinary bladder, it specifically refers to blood accumulating in the base area of the bladder. This condition can arise from trauma, medical procedures, or underlying health issues and may lead to discomfort, pain, and other urinary symptoms.
Pathophysiology
Structure
The urinary bladder is a hollow, muscular organ that stores urine before it is excreted. The fundus is the upper part of the bladder, opposite the urethral opening. It plays a crucial role in maintaining bladder structure and function.
Blood Supply
The bladder’s blood supply comes primarily from the superior and inferior vesical arteries, which branch from the internal iliac arteries. These arteries ensure that the bladder tissues receive adequate oxygen and nutrients.
Nerve Supply
The bladder is innervated by the pelvic nerves (parasympathetic) and hypogastric nerves (sympathetic). These nerves regulate bladder contraction and relaxation, enabling the storage and release of urine.
Types of Urinary Bladder Hematoma
- Traumatic Hematoma: Resulting from blunt or penetrating trauma to the bladder.
- Postoperative Hematoma: Occurs after surgical procedures involving the bladder.
- Spontaneous Hematoma: Develops without an obvious injury, often due to underlying medical conditions.
- Iatrogenic Hematoma: Caused by medical interventions, such as catheterization or biopsy.
Causes
- Blunt trauma to the lower abdomen or pelvis
