Answer

With the simplified approach, only a short-term trial of dietary therapy is needed to determine whether dietary modification is potentially adequate as a treatment. Medical treatment, usually beginning with thiazides, is used if dietary therapy alone is unsuccessful for any reason. Serum testing for PTH excess, hypercalcemia, and hypophosphatemia helps to identify those entities (hyperparathyroidism, renal leak hypercalciuria, renal phosphate leak) that should not be treated with dietary therapy alone.

The vast majority of hypercalciuric patients can be treated with this simplified plan. Ensuring that patients are retested while on the modified diet is important; otherwise, judging the effectiveness of the therapy or patient compliance is impossible.
