Ureaplasma Urealyticum: An Etiological Agent for the Development of Infection Stones in the Urinary Tract

Abstract

Infection stones, composed of magnesium ammonium phosphate (struvite) and/or calcium phosphate are the second most common type of stone in the urinary tract in man (1). Urinary tract infection with urease-producing bacteria is considered a pre-requisite for the formation of these stones (2). The enzyme urease splits urea into ammonia and carbon dioxide. In the alkaline urine so formed, the formation products of struvite and calcium phosphate can be exceeded.
