The formalized diagnosis of acute suppurative pyelonephritis

Using mathematical analysis methods, the authors try to develop algorithm of the diagnosis and early treatment of acute purulent pyelonephritis (APP). On the basis of 107 case histories (84 surgical, 12 conservative APP cases, 11 patients without the inflammation) characteristic symptoms were established. These may serve as parameters for the classification analysis and plotting curves indicative of the kidney involvement in the pyodestructive process. The analysis of the curves elicited that the pattern of the parameter changes reflects stages of purulent pyelonephritis in the kidney.
