Urinary response to oral potassium citrate therapy for urolithiasis in a private practice setting.
Oral potassium citrate therapy was recently approved for treatment of urolithiasis based on results of experiments in a university research setting. However, no supporting studies from private practice have been published. The present study was undertaken to assess the response to one week of oral potassium citrate therapy (60 mEq/day), with respect to urinary risk factors for kidney stones, in a private practice setting. A significant rise in urinary pH, citrate, and potassium excretion, accompanying a significant fall in calcium excretion, were observed. Urinary saturation of calcium oxalate was significantly reduced, as some risk factors in urolithiasis were corrected with oral potassium citrate therapy. The response to therapy in private practice was comparable to that observed in a university research setting.
