Vesicoureteral reflux

Vesicoureteral reflux (VUR) is an abnormal movement of urine from the bladder into ureters or kidneys. Urine normally travels from the kidneys via the ureters to the bladder. In vesicoureteral reflux the direction of urine flow is reversed (retrograde). (from wikipedia)

Image from Anatomybox.  This VCUG (voiding cystourethrogram) is a still image taken during fluoroscopy demonstrating reflux into both ureters.  The left ureter shows grade 4 reflux and the right ureter shows grade 3.

Clinical case: This 3 month old little girl presented to the hospital with fever at 2 months of age and was treated for a urinary tract infection.  She returns 3 weeks after completion of the treatment with a second UTI.  A renal ultrasound was performed and a vcug showed bilateral urinary reflux.
