A group of 47 patients with histologically confirmed chronic urinary bilharziasis underwent micturating cystourethrography to look for vesicoureteric reflux (VUR) and bladder neck stenosis (BNS); 13 patients were found to have VUR of varying grades (8 unilateral and 5 bilateral). None had evidence of BNS. Urinary tract infection (UTI), loin pain, hydroureter and renal failure were compared in patients with and without VUR. Of the 13 patients with reflux, 3 had UTI, loin pain was present in 8, 11 had an ipsilateral hydroureter and 2 presented with renal failure. In the 34 patients without reflux, 8 had UTI, loin pain was present in 22, 30 had hydroureter and 3 presented with renal failure. It was concluded that the incidence of UTI, loin pain, hydroureter and renal deterioration associated with bilharzial VUR was not significantly different from that found in bilharzial patients without VUR. Thus the clinical significance and the need for surgical correction of isolated VUR in bilharziasis are questionable.
