New renal scarring in children who at age 3 and 4 years had had normal scans with dimercaptosuccinic acid: follow up study

Abstract

Children with a urinary tract infection but unscarred kidneys after the third birthday have about a 1 in 40 risk of developing a scar subsequently, but after the fourth birthday the risk is either very low or zero. Thus the need for urinary surveillance is much reduced in a large number of children.
