Internal urethral sphincter spasms refer to involuntary contractions of the internal urethral sphincter, a muscle that surrounds the urethra and helps control urine flow. The spasms can cause a variety of urinary symptoms, such as pain, difficulty in urination, and urgency. Understanding the causes, symptoms, treatments, and diagnostic approaches can help individuals manage this condition effectively.
The internal urethral sphincter is a muscle located at the base of the bladder. Its main job is to maintain continence by preventing urine from leaking out of the bladder. It is an involuntary muscle, meaning it is controlled by the nervous system without conscious effort. Spasms of this muscle can occur due to various reasons, leading to symptoms that affect a person’s ability to urinate normally.
Pathophysiology of Internal Urethral Sphincter Spasms
Structure:
The internal urethral sphincter is composed of smooth muscle fibers and is part of the lower urinary tract. It is controlled by the autonomic nervous system, which means it functions without conscious thought.
Blood and Nerve Supply:
The internal urethral sphincter is supplied by both the sympathetic and parasympathetic nervous systems. The sympathetic system helps contract the muscle to maintain urine retention, while the parasympathetic system helps relax the sphincter for urination. The blood supply to this area is mainly from branches of the internal iliac artery.
Types of Internal Urethral Sphincter Spasms
- Primary Spasms: These occur without any underlying medical condition and may be due to stress or bladder irritation.
- Secondary Spasms: These spasms are caused by a specific condition, such as a urinary tract infection (UTI), neurological disorders, or bladder dysfunction.
