What condition is characterized by the urethral opening being located on the dorsal side of the penis?

The condition characterized by the urethral opening being located on the dorsal side of the penis is epispadias. This congenital defect occurs when the urethra does not properly form, resulting in the urethral opening being situated on the upper side (dorsal side) of the penis rather than at the tip.

Epispadias is often associated with other urinary tract abnormalities and can lead to issues with urinary continence and sexual function. It is crucial for clinicians to recognize this condition early to plan for potential surgical correction and management of any associated complications.

In contrast, cryptorchidism refers to an undescended testicle, which does not involve the urethral placement. Phimosis is the inability to retract the foreskin over the glans, typically not a structural defect concerning urethral placement. Hydrocele involves fluid accumulation around the testicle and is unrelated to urethral openings. Therefore, the focus on the position of the urethra in epispadias clearly differentiates it as the correct answer.
