Considerable progress has been made regarding pathophysiology, diagnosis, and medical prevention of recurrent renal stone formation. The medical approach is not applied widely because of the availability of extracorporeal shockwave lithotripsy and the complexity of medical diagnostic and treatment modalities. In this review, a simplified program for the medical management of stones is described. ⋯ The uncomplicated calcium stone disease, comprising the illness in the majority of patients with recurrent renal calculi, is characterized by normocalcemia, normouricemia, calcium stones, and the absence of urinary tract infection, bowel disease, or marked hyperoxaluria. Uncomplicated calcium stone disease is separated into a hypercalciuric group and a normocalciuric group. In the simplified treatment program, the hypercalciuric group would be offered thiazide plus potassium citrate, whereas the normocalciuric group would receive potassium citrate alone.
