Increase in the relative weight of post-ESWL COD renal calculi fragments following incubation in normooxaluric (0.28 mM) synthetic urine at pH = 6.5. Values represent the mean ± SEM for 12 fragments. a. Incubation in normocalciuric urine ([Ca total] = 3.75 mM) for 192 hours in the absence or presence of phytate. b. Incubation in hypercalciuric urine ([Ca total] = 6.25 mM) for 48 hours in the absence or presence of phytate. c. Incubation in hypercalciuric urine ([Ca total] = 6.25 mM) for 48 hours in the absence or presence of pyrophosphate. d. Incubation in hypercalciuric urine ([Ca total] = 6.25 mM) for 48 hours in the absence or presence of citrate.
