Epispadias is a rare physical condition where the urethral opening is located on the top or upper side of the penis or clitoris instead of at the tip. Although there are no exact synonyms for epispadias, some other terms that refer to similar conditions or related structures include hypospadias, which is when the urethra opening is on the underside of the penis or clitoris, and exstrophy, which can refer to a similar anomaly in the area of the bladder or rectum. Other related terms may include urethral meatus, which is the anatomical term for the urethral opening, and genitourinary malformation or congenital anomaly, which are more general terms for any physical defect in the reproductive or urinary systems.
