反复肾结石伴尿结晶患者加强补钙后结石治愈1例报道

One case report of patient with repeated kidney stone and urine crystal was cured after strengthening calcium supplementation

15%的男性在其一生中会有肾结石,并有35%~50%的几率在首次发病后5年内再次复发。虽最初建议限制反复肾结石患者的膳食钙摄入量,但有研究报道较低的膳食总钙摄入量与肾结石发病风险增加相关,而增加钙摄入量可能降低肾结石风险。本文报道了一例35岁男性患者,在限制钙摄入量后,尿结晶与肾结石仍复发,但加强补充钙/维生素D后,随访5年病情未再复发。

The lifetime prevalence of nephrolithiasis is 15%for men,with a 5-year recurrence rate of 35%to 50%after an initial event.Although it was initially recommended to limit calcium intake in these patients,a number of studies have reported association between lower total dietary calcium intake and increased risk of incident kidney stones,and that increased calcium intake might reduce the risk of incident kidney stones.We report a 35-year-old male who presented recurrent 8-years of nephrolithiasis and urine crystal with calcium intake restriction,and had no recurrence after 5 years of follow-up after intensive calcium and vitamin D supplementation.
