The external urethral orifice is the opening of the urethra, through which urine is excreted from the body. Dysfunction of this area refers to any abnormality, blockage, or impairment in its function, which can affect the ability to pass urine. This condition can be quite distressing and can impact a person’s quality of life. Below, we break down the details of external urethral orifice dysfunction, its causes, symptoms, diagnostics, treatments, and more in simple and easy-to-understand language.
Pathophysiology (Structure, Blood, Nerve Supply)
Structure: The external urethral orifice is located at the end of the urethra, which runs from the bladder to the outside of the body. It is controlled by muscles and tissues that help in urine release. When there is dysfunction, these muscles or tissues may not work as they should.
Blood Supply: The external urethral orifice is supplied with blood through the internal pudendal artery. This blood flow is crucial for maintaining the health of the tissues and muscles in the area.
Nerve Supply: Nerves from the pelvic plexus and pudendal nerve control the function of the external urethral orifice. These nerves help in the process of urination by regulating the contraction and relaxation of muscles.
Types of External Urethral Orifice Dysfunction
- Urethral Stricture – A narrowing of the urethra due to scar tissue, making it difficult for urine to pass.
- Meatal Stenosis – A condition where the external opening of the urethra becomes too tight.
- Urinary Incontinence – Involuntary leakage of urine due to weakened muscles around the orifice.
- Urethral Fistula – An abnormal connection between the urethra and another part of the body, often due to injury or surgery.
- Hypospadias – A congenital condition where the urethral opening is located abnormally on the underside of the penis in males.
- Ectopic Urethral Opening – When the urethra opens at an abnormal location, causing issues with urination.
- Neurogenic Bladder – Dysfunction in the nervous system affects the control of urination.
- Urethritis – Inflammation of the urethra caused by infection or injury.
- Urinary Retention – Difficulty emptying the bladder, often due to obstruction or nerve damage.
