Dissolution Kinetics of Calcium Oxalate Calculi
The solubility of some stone salts (e.g. struvite, uric acid and cystine) can be increased by altering urinary pH. Calcium oxalate (CaOx) solubility, however, changes little over the physiological pH range (4.5 to 7.5) but does increase at pH <4.0. To assess the feasibility of in vivo dissolution of CaOx by acidic irrigating solutions, we have determined the dissolution kinetics of CaOx calculi at low pH.
