Vesico-ureteral reflux in the dog

Abstract

Extract

Recent interest in the subject of vesicoureteral reflux (regurgitation of the vesical contents into the ureters) in man has lead to many experimental investigations of this phenomenon in dogs (Ross and Thompson, 1963 Ross, G. and Thompson, I.

Little, however, has been written on the naturally-occurring condition seen in canine clinical practice. In fact, apart from isolated reports from experimental workers (Barksdale and Baker, 1930 Barksdale, E. S. and Baker, W. W. 1930.
