尿石症预防饮食管理软件管理肾结石患者饮食摄入的应用价值

A computer software helps kidney stone patients controlling their diet for urinary calculus prevention

目的探讨计算机尿石症预防饮食管理软件管理肾结石患者饮食摄人的使用经验及有效性和实用性。方法37例肾结石患者分2组，第1组23例为软件使用组，用尿石症预防饮食管理软件管理饮食摄人；第2组14例为常规饮食指导组，只接受医生对患者的常规尿石症预防饮食指导。分别记录2组患者饮食管理前后尿量、动物蛋白、钙、草酸、嘌呤、钠和镁等尿石症相关成分每日平均摄入量的变化。结果软件使用组患者饮食管理前后尿量从（1121±171）ml增至（1703±245）ml;动物蛋白食物可食部分的摄入从（180±26）g减至（146±13）g；钙摄入从（657±124）mg减至（912±99）mg；富含草酸食物可食部分摄入从（33±8）g降至（16士6）g；富含嘌呤食物可食部分从（30±10）g降至（15±6）g；以上指标变化差异均有统计学意义（P＜0．01），而钠、镁的摄入无明显变化。常规饮食指导组患者饮食管理前后尿量、动物蛋白食物可食部分、钙、富含草酸食物可食部分、钠、镁等比较差异均无统计学意义（P＞0．05），仅富含嘌呤食物可食部分从（28±10）g降低到（15±5）g，差异有统计学意义（P＜0．01）。结论计算机尿石症预防饮食管理软件可帮助尿石症患者有效管理饮食，为患者提供全面系统的饮食防石信息。

Objective To help kidney stone patients controlling their diet for urinary calculus prevention using a computer software and to evaluate its efficacy. Methods Thirty-seven kidney stone patients were selected and divided into 2 groups, 23 patients in the first group managed their dietary intake using urinary calculus prevention diet controlling computer software, 14 patients in another group as control group received routine dietary educations for urinary calculus prevention by clinical doctors. Daily mean intakes of the stone disease-relevant food compositions of 2 groups before and after dietary management were calculated and compared. The stone disease-relevant food compositions include fluid, animal protein, calcium, oxalate, purine, sodium and magnesium. Results For the software using group, from before to after dietary management, urine volume increased from （1121±171）ml to （1703±245）ml, intake of the edible portion of animal protein containing food decreased from （180±26）g to （146±13）g, calcium intakes decreased from （657±124）mg to （912±99）mg, intake of the edible portion of oxalate-rich food decreased from （33±8）g to （16±6）g, intake of the edible portion of purine-rich food decreased from （30±10）g to （15±6）g, these differences were statistically significant, P〈0. 01 ,but for intake of sodium and magnesium, the differences were not statistically significant, P〉0. 05. For the patients of the control group, only intake of the edible portion of purine-rich food decreased from （28±10） g to （ 15±5） g, the difference was statistically significant, P〈0.01, for other food compositions intakes, differences were not statistically significant, P〉0.05.Conclusions The computer software could help kidney stone patients controlling their diet for urinary calculus prevention more efficiently. It could potientially be a tool for patients controlling diet to prevent urinary calculus disease.
