This susceptibility decreases with age as the length of the ureters increases as the children
grow. In children
under the age of 1 year with a urinary tract infection
, 70% will have VUR. This number decreases to 15% by the age of 12.
Although VUR is more common in males antenatally, in later life there is a definite female preponderance with 85% of cases being female.
Medical treatment entails low dose antibiotic prophylaxis until resolution of VUR occurs.
