Oral chemolysis means taking certain medications to dissolve 肾结石. Most kidney stones cannot be dissolved by medications. The exceptions are pure uric acid stones that may be dissolved by oral chemolysis by alkalinisation of the urine to the optimal pH of 7.2 Patients will need to adjust the dosage of the medication by self-monitoring the pH of their urine as over-alkalinisation of urine may lead to the formation of calcium phosphate stones.
