Renal ureter injury refers to damage to the ureter, the tube that carries urine from the kidney to the bladder. This type of injury can occur due to various reasons, including trauma, medical procedures, or underlying health conditions. Understanding this injury’s pathophysiology, types, causes, symptoms, diagnosis, treatment, and prevention is crucial for managing it effectively.
Pathophysiology
Structure
The ureters are muscular tubes about 10-12 inches long that connect each kidney to the bladder. They are lined with a layer of mucous membrane and surrounded by muscle tissue that helps push urine to the bladder.
Blood Supply
The blood supply to the ureters comes from several sources, including branches of the renal arteries, gonadal arteries, and iliac arteries. These blood vessels ensure that the ureters receive the necessary nutrients and oxygen.
Nerve Supply
The ureters are innervated by both sympathetic and parasympathetic nerves. The sympathetic nerves arise from the thoracic and lumbar segments of the spinal cord, while the parasympathetic supply comes from the sacral spinal cord.
Types of Renal Ureter Injury
- Traumatic Injury: Caused by blunt or penetrating trauma.
- Iatrogenic Injury: Resulting from surgical procedures or interventions.
- Obstructive Injury: Due to conditions like kidney stones or tumors.
- Ischemic Injury: Caused by reduced blood supply.
- Infectious Injury: Resulting from infections like tuberculosis.
