The urethra’s primary function is to transport urine out of the body, and in men, it also plays a crucial role in ejaculation. When scar tissue forms due to swelling, injury, or infection, it can narrow the urethra, restricting or slowing the flow of urine, a condition known as a urethral stricture.
A urethral stricture is a medical condition where scarring narrows the urethra, the tube responsible for transporting urine from the bladder to the outside of the body. This narrowing can be caused by injury, infections, or surgeries in the pelvic region. The reduced size of the urethra can lead to symptoms such as a slow or weak urine stream, difficulty starting or stopping urination, frequent urinary tract infections, or complete urinary retention in severe cases. In severe cases, a urethral stricture can lead to a sudden inability to urinate, known as acute urinary retention. Over time, the condition can worsen if left untreated, and prompt diagnosis and treatment are essential to avoid complications like kidney damage or chronic urinary tract infections. Treatment options may include dilation, surgery, or the use of a catheter.
Urethral strictures are most commonly caused by chronic inflammation or injury that leads to scar tissue formation, narrowing the urethra and making urination difficult. Scar tissue can develop gradually due to various factors, including injuries to the penis or scrotum, sexually transmitted infections (STIs) like chlamydia, the use of urinary catheters or surgical instruments during medical procedures, urethral or prostate cancer, and radiation therapy. In some cases, inflammation or injury occurs long before symptoms appear, while in others, the stricture develops soon after the initial damage.
