What is the congenital defect in which the urethra opens on the upper side of the penis?

The congenital defect where the urethra opens on the upper side of the penis is referred to as epispadias. This condition is characterized by an abnormal positioning of the urethral opening, which is situated on the dorsal (upper) aspect of the penis rather than at the tip. Epispadias often occurs alongside other anomalies, such as bladder exstrophy, and may require surgical intervention for correction.

Hypospadias, in contrast, involves the urethral opening being located on the underside of the penis, which is a different condition entirely. Phimosis refers to the inability to retract the foreskin over the glans of the penis, usually due to natural development or scarring. Castration is the surgical removal of the testicles and is unrelated to urethral positioning.

Understanding the distinctions between these terms is essential for accurately identifying and coding congenital conditions in clinical documentation. Recognizing the specific location of the urethral opening is crucial for proper diagnosis and treatment planning.
