Internal urethral sphincter pain is a condition affecting the urethra, the tube that carries urine from the bladder to the outside of the body. The internal urethral sphincter is a muscle that controls the release of urine. When pain arises in this area, it can significantly affect a person’s quality of life. Understanding the causes, symptoms, treatments, and when to seek medical help is crucial for anyone experiencing urethral pain.
The internal urethral sphincter is a smooth muscle located at the junction where the bladder and the urethra meet. It functions to prevent urine leakage by keeping the urethra closed until it is appropriate to release urine during urination.
Pathophysiology of Internal Urethral Sphincter Pain
- Structure: The internal urethral sphincter consists of smooth muscle fibers that contract and relax to control urination.
- Blood Supply: The blood supply to the urethra, including the sphincter, is provided by the internal iliac artery.
- Nerve Supply: The nerve supply comes from the autonomic nervous system, including the pelvic nerves, which control involuntary muscle movement.
Types of Internal Urethral Sphincter Pain
- Acute Pain: Sudden, intense discomfort that often requires immediate medical attention.
- Chronic Pain: Persistent pain that lasts for weeks or months, affecting daily activities.

Diagnostic Tests for Internal Urethral Sphincter Pain
- Urine analysis: To check for infection.

- Post-void residual test: Measures how much urine is left in the bladder after urination.
- Bladder biopsy: To rule out bladder cancer.
- Pelvic exam: To check for organ prolapse.
- Prostate exam (in men): To check for prostate issues.
- STD tests: To rule out sexually transmitted infections.
- Magnetic resonance urography: For detailed urinary tract imaging.
- Pelvic MRI: To assess pelvic muscle function.
- Blood tests: To check for infection or other underlying conditions.
- Voiding diary: Records urination patterns.
- Cytology test: Examines urine for abnormal cells.
- Rectal exam (in men): To assess the prostate and surrounding areas.
