“…The performed studies, relative to the effect of trace elements on the mineralization and 'in vitro' crystalliza tion, demonstrate that some of the trace elements act as crystal growth inhibitors of calcium oxalate [14] and they can also act as promoters of the primary aggregation, as can be deduced from the calcium oxalate crystallization studies performed in the presence of zinc and copper. Thus, when observing Figure 1, it is evident that when cal cium oxalate was precipitated in the presence of zinc or copper, the obtained crystals presented a considerably more imperfect crystal structure, and more irregularities on the crystal surface were detected ( fig.…”

“…Thus, it was seen that lower urinary con centrations of Ni, Mn and Li were present in stone-form ers rather than in healthy people, nevertheless, no differ ences were found in the urinary concentrations of Zn, Cu, Al, Ti, Cr, Fe, Co, Sr, Mo and Pb between stone-formers and healthy people [ 1 ]. It has also been reported that some of these ions as Zn can act as effective promoters in renal stone formation [2], It must also be considered that ions as Cu, Zn, Mn, Mg and Fe have been described as inhibi tors of calcium oxalate crystal growth [3][4][5][6],…”

The possible effects of Zn and Cu in oxalocalcic urolithiasis were investigated. The formation of calcium oxalate crystals in the presence of Zn and Cu demonstrated that their morpholoy is clearly affected by these ions. Thus, when such ions were present in a number of higher concentrations, a notable increase in the primary aggregation was clearly detected. On the other hand, Zn and Cu urinary levels were determined in groups of stone-formers and healthy people. Zinc urinary concentration was significantly lower for lithiasic than for healthy people and the copper urinary concentration was lower for lithiasic than healthy males, but both female groups had a similar copper urinary concentration. The mentioned differences disappeared when serum levels were considered. These obtained results have been comparatively evaluated with those obtained by other authors. When considering all the commented aspects, it is concluded that no important direct action of zinc and copper on oxalocalcic calculi genesis takes place.
