Imaging studies of ectopic ureter inserting into the vagina

Ultrasound images of the right kidney shows a hydronephrotic upper pole moiety (arrow) of a duplex collecting system (panel A) and insertion of an ectopic hydroureter (panel B) posterior to the uterus (UT) and below the bladder (BL) (arrowhead). Magnetic resonance imaging (panel C) shows hydronephrosis of the upper pole moiety (arrow) with insertion of the dilated ureter below the bladder (BL) (arrowhead). Panel D is a retrograde contrast radiographic study of the ectopic ureter performed through the vagina (arrowhead).
