Experimental study of the pressure-volume and pressure-time relations in the completely obstructed pelvis of the porcine kidney. Part 1: Introduction and theory.
Little is known about pressure-volume and pressure-time relations of the obstructed renal pelvis. In a series of experiments with pigs the completely obstructed renal pelvis was infused with Ringer's lactate at a constant rate of 2 ml/min. On the basis of these experiments a mathematical description is given of the pressure-volume and pressure-time relations that were recorded.
