[Vesicoureteric reflux].

Vesicoureteric reflux (VUR) is defined as the retrograde passage of urine from the bladder into the upper parts of urinary system. The first symptoms may be seen in infancy, but may as well develop during entire life of the patient, in some patients being atypical. A quick diagnosis is of utmost importance since any delay in the treatment can cause many serious complications such as recurrent urinary tract infections (UTI), renal scarring development, hypertension and renal insufficiency.
