The Whitaker Test



The Whitaker perfusion pressure-flow (PPF) study was developed to determine the presence, or absence, of obstruction in the dilated upper urinary tract in children. It is now uncommon to resort to this invasive investigation, but it still has a role in the management of pediatric or adult patients with hydronephrosis, or hydronephroureterosis, where the presence of obstruction remains unclear as a consequence of equivocal diuresis renography.
