A renal ureter stricture is a narrowing of the ureter, the tube that carries urine from the kidney to the bladder. This condition can block the flow of urine, leading to various health issues.
Understanding renal ureter strictures is crucial for early detection and treatment, which can help prevent complications like kidney damage.
Pathophysiology
Structure of the Renal Ureter
The ureter is a muscular tube about 10-12 inches long. It has three layers: the inner mucosa, the middle muscular layer, and the outer fibrous layer. A stricture occurs when the normal diameter of the ureter is reduced.
Blood Supply
The ureters receive blood from various arteries, including the renal, gonadal, and iliac arteries. Proper blood flow is essential for the ureter’s function and healing.
Nerve Supply
The nerve supply to the ureters comes from the autonomic nervous system, which controls involuntary actions like urine transport.
Types of Renal Ureter Stricture
Congenital Stricture
These are present at birth and can be caused by developmental issues during pregnancy.
Acquired Stricture
These develop over time and can result from injury, inflammation, or infection.
Other Classifications
Strictures can also be classified based on their location (proximal, mid, or distal ureter) or the extent of narrowing.
Causes of Renal Ureter Stricture
