[Primary pyelonephritis (the focal problem)].

On different experimental models of pyelonephritis in dogs and rabbits an experiment for the classification of the pathogenesis of this disease with the special questioning of the possible development of the so-called primary pyelonephritis was performed. A series of experiments consisted of 3 groups: 1. Injection of an E.-coli-suspension into the musculature of the urinary bladder of dogs and rabbits. 2. Injection of an E.-coli-suspension into the testicles of rabbits. 3. Injection of an E.-coli-suspension into the seminal bladders of rats. The experiments lasted 2 to 15 days and 16 to 110 days, respectively. In the second series of experiment in rats and rabbits an E.-coli-suspension was injected into the gall-bladder of rats and rabbits. Bacteriologic blood cultures and histologic investigations of the kidneys, the ureters, the wall of the urinary bladder and the adjacent lymphatic and fatty tissue as well as of the gall-bladders were performed. The results showed that the pyelonephritis developed secondarily after the infection of the other infected organs by haematogenic or interstitial dissemination of the pathogenic agents. Conclusions are drawn: 1. Every pyelonephritis, also the haematogenic, is a secondary process. 2. Therefore all must be done to find out the primary inflammatory change in the organism and to cure it. 3. Severe forms of the pyelonephritis may, on the other hand, effect as focus and evoke in inflammation of other organs on lymphogenic and haematogenic way. 4. Taking into consideration the facts mentioned perhaps the great number of pyelonephritiides having become latent might be reduced.
