General Gross Description
•Ureteral duplication may be partial or complete.
•Most
duplications are partial with two ureters draining separate pelvic
collecting systems of one kidney and joining distally to form one ureter
before entering the bladder.
•Complete duplications are less common where
two ureters drain one kidney and have separate orifices into the urinary
bladder.
•Even less common are situations where one of the duplicated
ureters empties into the vagina, urethra, uterus, seminal vesicles,
verumontanem or ejaculatory ducts.
