本文对照了21例特发性泌尿系结石患者同30例正常人的有关枸橼酸代谢的化验参数。血枸橼酸分别为2.40±0.58mg/dl和2.22±0.40mg/dl(P>0.05);24小时尿枸橼酸166±105mg/24h和327±134mg/24h(P<0.01);尿枸橼酸/钙比值1.078±1.078和2.50±1.30(P<0.01);尿枸橼酸/肌酐比值0.164±0.107和0.339±10.177(P<0.01)。说明尿中枸橼酸数量,特别是尿中枸橼酸同钙比值的降低是泌尿系结石形成的重要原因之一。
In this paper, 21 patients with idiopathic urolithiasis with 30 normal subjects related to citrate metabolism test parameters. Citric acid was 2.40 ± 0.58 mg / dl and 2.22 ± 0.40 mg / dl respectively (P> 0.05); Urine citrate 166 ± 105 mg / 24h and 327 ± 134 mg / 24h (P <0.01) Citrate / creatinine ratios were 1.078 ± 1.078 and 2.50 ± 1.30 respectively (P <0.01); urinary citrate / creatinine ratios were 0.164 ± 0.107 and 0.339 ± 10.177 (P <0.01). Description of the amount of citric acid in urine, especially urinary citrate with the ratio of calcium is one of the important reasons for the formation of urinary stones.
