THE GROWTH OF THE KIDNEYS IN CHILDREN WITH VESICOURETERIC REFLUX

Abstract
In a retrospective study, 69 kidneys with VUR [vesicoureteric reflux] were divided into 2 groups: one group (A) where VUR stopped within 1 yr after operation or conservative treatment and a 2nd group (B) where VUR continued for more than 1 yr. Group A had somewhat more severe grades or reflux than group B. The number of infections were practically the same in the 2 groups. The length of the kidneys was measured at the time of diagnosis and compared with the length at the most recent urography after VUR stopped (group A) on average 2 yr and 3 mo. later and with the most recent urography while VUR was still present (group B) on average 1 yr and 9 mo. later. In group A 85% had increased in absolute length while the figure was 60% in group B. If the relative growth was calculated (the kidneys'' length in relationship to L1-L3 [upper edge 1st lumbar vertebra to lower edge 3rd lumbar vertebra] distance), 60% in group B had decreased while only 30% in group A had decreased.
