title: Application of perfusion pressure measurement to problems of upper urinary tract dilatation in children.
abstract: A simplified technique of measuring perfusion pressure in the equivocally obstructed upper urinary tract of children is described. Twelve patients with dilated renal pelves or ureters encountered in an 18-month period have been investigated. The findings in the majority of cases were contrary to those anticipated from the radiological appearances. This test of obstruction has wide application in the management of paediatric urological problems.
