Meatal stenosis is a medical condition that involves the narrowing of the urethral meatus, which is the opening through which urine exits the body. This condition is more common in males than females and is often associated with circumcision.

Causes

The exact cause of meatal stenosis is not known, but it is often associated with circumcision. The theory is that the exposure of the meatus to air and rubbing against clothing leads to irritation and scarring, which can cause the meatus to narrow. Other possible causes include infection, trauma, and inflammation.

Symptoms

The symptoms of meatal stenosis can vary depending on the severity of the condition. Common symptoms include a thin, high-pressured urinary stream, dysuria (painful urination), and hematuria (blood in the urine). In severe cases, it can lead to urinary retention, where the individual is unable to empty their bladder completely.

Diagnosis

The diagnosis of meatal stenosis is usually made based on the symptoms and a physical examination. The doctor may also perform a urinalysis to rule out other conditions. In some cases, a urethrogram may be performed to visualize the urethra and confirm the diagnosis.

Treatment

The treatment for meatal stenosis usually involves surgery to widen the meatus. This is typically done under general anesthesia. The procedure, known as meatotomy, involves making a small cut in the meatus to widen it. After the procedure, the individual may need to apply a topical cream to the area to promote healing and prevent scarring.
