Renal ureter obstruction is a blockage in the ureter, the tube that carries urine from the kidney to the bladder. This condition can lead to serious complications if not addressed promptly.
Pathophysiology
Structure:
The ureter is a muscular tube about 10-12 inches long. It connects the kidneys to the bladder. Each kidney has its own ureter.
Blood Supply:
The ureters receive blood from several arteries, mainly branches from the abdominal aorta and the renal arteries. Proper blood supply is crucial for the health of the ureters and kidneys.
Nerve Supply:
Nerves from the renal plexus supply the ureters. They help control the muscle contractions that move urine from the kidneys to the bladder.
Types of Renal Ureter Obstruction
- Partial Obstruction: Some urine can still pass through.
- Complete Obstruction: No urine can pass, leading to serious complications.
- Unilateral Obstruction: Affects one ureter.
- Bilateral Obstruction: Affects both ureters.
Causes
- Kidney Stones: Hard deposits that form in the kidneys.
