REDUCTION OF URINARY STONE RECURRENCE BY DIETARY COUNSELING AFTER SWL

To reduce the recurrence rate of urolithiasis, dietary counseling was conducted for calcium-stone patients, Sixty-six patients received diet ary counseling and were in principle instructed to use the Recommended Dietary Allowance for Japanese as their goal, Seventy-three patients did not undergo the counseling, Comparison of the dietary intake of th e patients with the dietary requirements for Japanese revealed that pr otein intake, especially animal protein intake, was higher and calcium intake lower in the patients, As a result of the counseling, intakes of total protein, animal protein, fat, and carbohydrates were ail redu ced, Patients in the stone recurrence-free group excreted less oxalate than those in the recurrent one, The excretion of oxalate was then re duced and urine volume increased owing to the diet counseling program, The stone recurrence rate of the group participating in the diet coun seling was lower than that of the group not taking part, The recurrenc e rate of the hyperoxaluric: group was higher, with statistical signif icance, than that of the normooxaluric group among those not receiving the dietary counseling, With dietary counseling, the recurrence rate significantly decreased in the hyperoxaluric patients, Thus, the reduc tion in the rate of stone recurrence resulting from participation in t he diet counseling program seemed to be attributable to the decrease i n urinary oxalate excretion, Dietary counseling seems to be a useful m easure to prevent urinary stone recurrence.
