Abstract

Few systematic studies on net aggregation of calcium oxalate (CaOx) in human urine have been carried out. Ryall et al. (1) analyzed simultaneously crystal growth and aggregation, expressing growth as the net increase in crystal volume and aggregation as a function of the net change in crystal number. Drach et al. (2) used a continuous-flow crystallization system in a series with a Couette agglometer to analyze the effect of human urine on suspensions of CaOx crystals. There was a tendency for larger crystal aggregates to form in urine of stone formers than in normal urines.
