Urethral duplication

Urethral duplication is a rare condition in which either a part or the entire urethra is duplicated. It usually occurs in the sagittal plane and the more dorsal copy is usually the duplication.

A urethral duplication may occur due to a variety of developmental miscues. In a woman, it is thought to arise from delayed fusion of the Mullerian ducts and urogenital sinus 2

In males, a partial or complete duplication of the urethra can be seen with urethography. In males, two separate meatuses with the ability to void through both is a more common configuration.

Possible duplication of the female urethra is better studied with MRI.  Two high signal-intensity central spots may be apparent on an axial view of the pelvis in the region of the urethra.

In a male, hypospadias can be considered (glanular dimple not patent).
