Renal growth retardation in children: sign suggestive of vesicoureteral reflux?

Abstract

Of 141 children undergoing surgery for vesicoureteral reflux detected by voiding cystourethrography, preoperative excretory urography demonstrated signs suggestive of vesicoureteral reflux in 154 (67.5%) of 228 refluxing ureter. In 48 refluxing ureters (21%) renal growth retardation was the only sign; the latter was appreciated by applying the index described by Hodson, that is, the ratio of bipolar parenchymal thickness to total renal length. It was concluded that it is important to systematically calculate this simple index from every child's excretory urogram.
