<unk>  (or ureteral<unk>  is a medical condition where the ureter, rather than terminating at the urinary bladder, terminates at a different site. In males this site is usually the urethra, in females this is usually the urethra or vagina. It can be associated with renal dysplasia, frequent urinary tract infections, and urinary incontinence (usually continuous drip incontinence).<unk> s are found in 1 of every 2000–4000 patients, and can be difficult to diagnose, but are most often seen on CT scans.<unk>  is commonly a result of a duplicated renal collecting system, a duplex kidney with 2 ureters. In this case, usually one ureter drains correctly to the bladder, with the duplicated ureter presenting as<unk> . The embryology that explains the pathology of an<unk>  is a cephalad origin of the ureteral bud on the mesonephric duct. With an abnormally long common excretory duct, the ureter never becomes incorporated into the bladder, and, therefore, remains<unk> . In the female, the most common locations of an<unk>  are the bladder neck, urethra, or Gartner's duct which lies between the urethra and the anterior vaginal wall.
