为探讨尿路梗阻与结石形成的关系,作者用30只大白鼠进行了尿路机械性梗阻影响肾内晶体出现的实验研究,于肾盂及输尿管交界处作成梗阻性尿液淤积,喂食2.5％乙二醇形成肾内结石晶体。结果发现在梗阻后48小时出现的病理变化较严重,晶体开始成集簇性沉积,皮质多于髓质,梗阻的右肾 To explore the relationship between urinary tract obstruction and stone formation, the author of 30 rats with urinary tract mechanical obstruction affect the appearance of intra-renal crystals in the experimental renal pelvis and ureter junction obstruction caused by urine sedimentation, feeding 2.5% B Diol to form intra-renal calculi crystals. The results showed that 48 hours after obstruction appeared more serious pathological changes, the crystals began to become a cluster of deposits, more than the medulla cortex, obstruction of the right kidney
