在23例单侧性含钙肾结石者与9例单侧性肾积水的非尿石者中,对比研究了分侧肾盂尿的成石因素,发现尿石组患侧肾盂尿结晶检出率为34.8％,健侧为8.4％,P<0.05。随着肾积水程度加重,尿Ca浓度显著降低。在5例仅有轻度肾积水的尿石者中,发现患侧尿钙浓度显著高于健侧(P<0.02),并有高尿P、Ox、uA及低尿Mg浓度等3项以上异常。尿石组患肾尿Ca与P、Mg浓度相关性与健肾等显著不同(P<0.05～0.01),提示患结石肾肾小管有引起结石形成的原发性功能异常。
In 23 cases of unilateral calcific nephrolithiasis and 9 cases of unilateral urinary hydronephrosis, contrastive study of paracliarial urolithiasis factors found urolithiasis ipsilateral pyelogram of urine were detected The rate was 34.8% and the contralateral side was 8.4%, P <0.05. As the degree of hydronephrosis aggravated, urinary Ca concentration was significantly reduced. In 5 cases of urolithiasis with mild hydronephrosis, ipsilateral urinary calcium concentration was significantly higher than that of healthy side (P <0.02), and there were 3 items of high urinary P, Ox, uA and low urinary Mg concentration The above exception. Urine stone group of renal urinary Ca and P, Mg concentration and kidney Kidney significantly different (P <0.05 ~ 0.01), suggesting that suffering from stone and kidney tubules have caused the formation of primary dysfunction stones.
