Abstract

Infection with urease-producing bacteria as Proteus, Klebsiella, Pseudomonas or Staphylococcus has so far been considered a prerequisite for the formation of infection concrements, i.e. concrements composed of struvite and/or carbonate-apatite. Urease splits urea into ammonia and carbon dioxide and in the alkaline urine so formed, the formation products of struvite and carbonate-apatite are exceeded. In a recent clinical study a relationship between Ureaplasma urealyticum and infection concrements in the upper urinary tract was demonstrated. U. urealyticum is a urease-producing microorganism commonly occurring in the lower urinary tract of adults but not ordinarily in the upper urinary tract. The Ureaplasmas are not detected with conventional bacterial culture techniques, which may explain why infection concrements have not previously been associated with the organism.
