title: Pressure flow studies in hydronephrosis.
abstract: 44 patients with idiopathic hydronephrosis underwent intrapelvic pressure flow studies. An increased basal pressure and an increased pressure during flow loading were found compared with the findings in 10 control kidneys. The method is relatively easy to perform and has few complications. It may be of value in determining the degree of obstruction in equivocal cases of dilated pelvis.
