ABSTRACT
Another classification described by Williams and Kenawi3 divided the sagittal duplications into four groups: epispadiac or hypospadiac, depending on the position of the accessory meatus; spindle urethra, where the urethra splits into two then reunites; and Y duplication, with a pre-anal or perineal accessory channel. The epispadiac and hypospadiac groups were further subdivided into complete (the two urethras leave the bladder separately and remain separate), incomplete (one channel divides distally), and abortive (a blind ending penile sinus).
