Abstract
The lesion principally responsible for chronic, or recurrent, urinary tract infection is a focus in the interstitial tissue of the kidney. Most cursory antimicrobial therapy suppresses the manifestations of lower urinary tract involvement but does not eradicate the renal focus. In order to cure rather than merely suppress the infection, it is imperative that, as early as possible, steps be taken to isolate and identify the etiologic microorganism and to determine its sensitivity to antimicrobial agents. Based on this information sufficient amounts of drug should be given for an adequate period (probably at least two weeks) to eradicate the infection within the renal tissue. Such a program would tend to reduce the number of cases in which irreversible renal failure develops from chronic pyelonephritis.
