Monosodium urate (NaU), ammonium urate (NH4U) and uric acid (UA) urinary relative saturations were studied in 15 normo-uricuric calcium oxalate (CaOx) recurrent stone formers whose CaOx relative saturation was identical to age- and sex-matched controls. NaU and NH4U relative saturations were constantly below 1 and not higher in stone formers than in controls, suggesting that heterogeneous nucleation is an unlikely mechanism of CaOx stone formation in vivo. Such values of NaU relative saturation would also tend to rule out any change in the CaOx formation product or urinary inhibitory activity. However, at a given urinary flow rate, NaU relative saturation was suggestively higher in stone formers than in controls. Some disturbance in the equilibrium between NaU and urinary inhibitors might then exist even in normo-uricuric CaOx stone formers.
