It is easier to prevent a disease than to cure it. This postulate is a foundation stone of the contemporary medicine, furthermore its mission. The Chronic Kidney Diseases (CKD), amongst them the Chronic Pyelonephrites (CP) and the mass kidney reduction take an important place in human pathologies in general, and in particular in renal ones. The Chronic Pyelonephrites are chronic renal pathologies, which on one side are of various causes and on the other side are multi systemic. At the same time they tend, earlier or later, depending on their course, to bring the patient towards the Chronic Kidney Insufficiency in stage of uremia, consequently in need of substitution therapies e.g. dialysis, peritoneum dialysis or transplant. It is worthy to emphasize that from the prevention and correct cure of CP make profit the patients, the family, the state and in the last analyses the entire society, because in that way the budget expense destined for the fore going substitution cures, dialysis, peritoneum dialysis or transplant, is considerably reduced. The same should be mentioned in relation to the CP and the mass kidney reduction, speaking about our country, which are still at the first place as the very cause of Chronic Kidney Insufficiencies (CRI), later on advancing toward uremia and terminal uremia along with its grave consequences. In general the very foundation of the CP is on the infections of urinary roads, in particular on the complicated ones, among them it should be mentioned-congenital kidney anomalies, renal calculosis so much present in our country, and pathologies of segment or vesical-ureteral reflux, and rarely the pathologies of prostate., Fejzi Alushi, Nestor Thereska, and Literatura
