The ability of pressure flow studies and renography to assess obstruction was compared in 32 patients with equivocal upper urinary tract obstruction. The renogram failed to confirm the presence or absence of obstruction in 39 per cent of the cases as shown by the pressure flow study. Both studies have advantages, disadvantages and technical pitfalls.
在32例上尿路梗阻情况不明确的患者中，对压力流研究和肾造影评估梗阻的能力进行了比较。如压力流研究所示，肾造影在39%的病例中未能证实梗阻的存在与否。这两项研究都有其优点、缺点和技术上的缺陷。
