Assessment of renal blood flow in dogs: analysis of 131I-hippuran blood clearance in healthy dogs and in dogs with proteinuria.
In 30 clinically healthy dogs (weights 7.5 to 57 kg) and in 41 proteinuric dogs the 131I-hippuran blood disappearance curve after single injection was determined (0 to 90 minutes), described by a bi-exponential function and analysed according to a two compartment model. The dependence of the blood clearance (C), representing an effective renal blood flow, on the bodyweight (W) (kg) could be described with both a linear function (C = 61 + 13.2 W ml min-1) and a power function (C = 30.56 W0.79 ml min-1) in the healthy dogs. The results of the regression between blood clearance and bodyweight were reproducible (r = 0.92, n = 10 residual error 12 per cent, P less than 0.01).
