Ectopic ureter (or ureteral ectopia) is a medical condition where the ureter, rather than terminating at the urinary bladder, terminates at a different site.[1][2] In males this site is usually the urethra, in females this is usually the urethra or vagina.[3] It can be associated with renal dysplasia,[4] frequent urinary tract infections, and urinary incontinence (usually continuous drip incontinence).[5] Ectopic ureters are found in 1 of every 2000–4000 patients,[6] and can be difficult to diagnose, but are most often seen on CT scans.[7]
Ectopic ureter 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 ectopic.[8]
