Which condition involves inflammation of the urethra?

Urethritis is the condition that specifically involves inflammation of the urethra, which is the tube that carries urine from the bladder to the outside of the body. This inflammation can result from infection, injury, or irritation, and may cause symptoms such as pain during urination, frequent urination, and discharge from the urethra. Identifying urethritis is important as it can highlight underlying causes such as sexually transmitted infections or other inflammatory conditions.

In contrast, cystitis refers to inflammation of the bladder, which can occur due to infections but involves different structures and symptoms. Nephritis involves the inflammation of the kidneys, which can lead to more serious issues such as kidney damage. Uretritis appears to be a misspelling of urethritis and is not a recognized medical term or condition. Understanding these definitions helps in distinguishing between various urinary tract conditions.
