Which condition involves a urethral opening located on the dorsum of the penis?

The condition characterized by a urethral opening located on the dorsum of the penis is epispadias. This congenital anomaly results in the urethra not forming properly, leading to its opening on the top side (dorsal side) rather than the tip of the penis.

Epispadias can vary in severity, and it is often associated with other urinary or genital tract anomalies. The proper localization of the urethral opening is crucial for normal function and aesthetics, and understanding this condition helps in diagnosing and managing related complications effectively.

In contrast, hypospadias involves the urethral opening located on the underside of the penis, phimosis refers to a condition where the foreskin cannot be easily retracted, and priapism is an abnormal and prolonged erection not associated with sexual desire or stimulation. Each of these conditions presents differently and requires distinct management strategies, highlighting the importance of accurately identifying the type of urethral anomaly.
