The nutcracker phenomenon refers to compression of the left renal vein between the aorta and the superior mesenteric artery. Clinical features are hematuria, abdominal pain, left flank pain, pelvic or scrotal discomfort due to varicocele or ovarian vein syndrome. In this report, 2 patients with orthostatic proteinuria, in whom nutcracker phenomenon was detected as a cause, are presented. One of them had posterior nutcracker with also asymptomatic varicocele that was detected during ultrasonographic examination. Nutcracker phenomenon is a rare but important clinical condition that should be considered in the differential diagnosis of patients with proteinuria and hematuria.
胡桃夹现象是指左肾静脉在腹主动脉和肠系膜上动脉之间受到压迫。其临床特征包括血尿、腹痛、左侧腰痛、因精索静脉曲张或卵巢静脉综合征引起的盆腔或阴囊不适。在本报告中，介绍了2例直立性蛋白尿患者，其病因被检测为胡桃夹现象。其中1例为后胡桃夹现象，同时在超声检查中发现了无症状精索静脉曲张。胡桃夹现象是一种罕见但重要的临床情况，在蛋白尿和血尿患者的鉴别诊断中应予以考虑。
