Meatus - Definition


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.
