Healthy, mature male Beagles (24) were examined radiographically for vesicoureteral reflux (VUR) by maximum-distention retrograde urethrocystography. Bilateral VUR was observed in 9 dogs and unilateral VUR was observed in 3 dogs. The VUR occurred when the bladder was full or nearly full when maximum bladder filling was defined by trigonal-prostatic urethral dilation. The refluxed contrast medium reached the renal pelves in all but 3 of the 21 affected ureters.
