A meatus, in anatomy, is the orifice of an organic duct. The urinary or urethral meatus refers to the tip of the urethra
, the opening for discharging urine from the bladder to the outside of the body
. There are numerous intercellular spaces in the body, which can sometimes be narrowed and cause various disorders: this is called meatal stenosis. The most common causes of the constrictions are genetic
malformations or frequent infections
. Surgery, called a meatotomy, can return the meatus to its normal size, mainly practiced at the urethra, especially in men.
