Ascending Vasa Recta Hematoma

Pathophysiology

• Structure: The vasa recta are straight blood vessels that branch off from the efferent arterioles of the juxtamedullary nephrons in the kidneys. They play a vital role in the counter-current exchange system that maintains the kidney’s ability to concentrate urine.
• Blood Supply: The blood supply to the vasa recta comes primarily from the renal? arteries. They ensure that oxygen and nutrients are delivered to the renal medulla, which is crucial for kidney function.
• Nerve Supply: The vasa recta are innervated by the sympathetic nervous system, which helps regulate blood flow in response to various physiological demands.

Types of Ascending Vasa Recta Hematoma
