[Three cases report on the epispadiac urethral duplication in male].

A case of complete type and two cases of incomplete type of epispadiac urethral duplication are reported. In the complete one, the accessory urethra (14 cm in length) opened 1.5 cm proximal to the dorsum of the penis. In two cases of incomplete type, the epispadiac openings located at the base of the penis or higher. The sinuses were lined with transitional epithelium proximally, and with squamous cells on the distal half of the accessory urethra, which suggests a developmental origin. We conclude that these sinuses may etiologically represent the identical origin without regard to complete type or incomplete type.
