The urethra is the tube that drains urine from the bladder. The end of the urethra on the tip of the penis is called the meatus. Meatal stenosis is the narrowing of the meatus. On exam, the meatus appears nearly pin-point. Boys with meatal stenosis typically have a urinary stream that deflects upward or is prolonged. It is often a challenge for them to stand to urinate.
Nasal meatus. A nasal meatus is a nasal passage of the nasal cavity, of which there are three; the superior meatus, middle meatus and inferior meatus. These nasal meatuses are also known as meatus nasi superior, meatus nasi medius, and meatus nasi inferior. (A meatus is a passage or opening in the body, especially one which is open to the exterior).
