Urinary Tract Infections in Renal Stone Disease

Abstract

Urinary infections have a well-documented relationship with urinary stone disease. Urea-splitting organismus such as Proteus, Klebsiella, Pyocyaneus, and Staphylococcus play an important role in the genesis and growth of struvite and calcium phosphate calculi (1–3). In previous investigations of stone formers the frequency of infectioninduced stone disease was found to vary between 6% and 25% (3–4). The frequency of urinary infections in nonselected stone-forming populations is, however,not well known. This study was designed to find out how often urinary infections are related to stone disease and which microorganisms are most often found in a stone-forming population.
