of these 25 patients 11 had a nephropathy as the cause of renal failure that was unrelated to reflux ( for example glomerulonephritis ) and 12 had , in addition to vesicoureteral reflux , a history of urinary tract infections and chronic pyelonephritis , which seems to be significant in the etiology of terminal renal failure in our patients ( 14 per cent ) .
