The influence of zinc and citrate on urease-induced urine crystallisation.

H Hedelin1, L Grenabo, J Hugosson, S Pettersson.   

Abstract

Zinc reduced and citrate promoted the urease-induced pH increase in synthetic urine. Secondary to this, the precipitation of magnesium ammonium phosphate and calcium phosphate was influenced. Independent of this pH-related effect, zinc also increased the precipitation of magnesium ammonium phosphate and decreased the calcium phosphate precipitation. These observations were not totally reproducable in human urine.
