摘　　要：目的观察胡桃夹现象病儿体位改变对改善左肾静脉症状的临床意义。方法用位相显微镜检测28例病儿直立位和蹲位各20 min后的尿红细胞形态和数量,并用彩色多普勒超声测量左肾静脉最窄处和最宽处内径,将两组数据进行对比分析。结果胡桃夹现象病儿蹲位20 min后正形红细胞排出数量和左肾静脉近心端内径/远心端内径比值,与直立位20 min后比较,差别有统计学意义(t=2.04、9.88,P<0.05、0.01)。结论特定体位对左肾静脉狭窄的病儿症状有明显改善。Objective To observe the clinical significance of a change of posture in improving left renal vein symptoms in children with nutcracher phenomenon （NCP）. Methods The amount and morphology of red blood ceils in urine of 28 children with NCP collected on squatting and standing position for 20 rain were checked with phase microscope. The internal diameter of left renal vein at narrowest and broadest part was measured by Doppler sonography, the data obtained were compared. Results The data obtained from squatting position were significantly different from that obtained on standing position （t= 2.04,9.88;P〈0.05, 0.01）. Conclusion Definite posture obviously improves the symptoms due to stricture of left renal vein in children with NCP.
