Nutcracker syndrome (NCS), the left renal vein hypertension due to compression between aorta and superior mesenteric artery, may present with hematuria, flank pain and proteinuria. We report a 6-year-old girl with episodic macroscopic hematuria who was diagnosed as NCS with Doppler ultrasound and 3D computerized tomography angiography. She was managed conservatively with spontaneous resolution of macroscopic hematuria. With this case we would like to emphasize that in children with hematuria and orthostatic proteinuria without an apparent cause, a great index of suspicion and appropriate imaging is necessary for the diagnosis of NCS.
胡桃夹综合征（NCS）是由于腹主动脉和肠系膜上动脉之间的压迫导致左肾静脉高压，可能表现为血尿、腰痛和蛋白尿。我们报告了一例 6 岁女孩，间歇性出现肉眼血尿，经多普勒超声和 3D 计算机化血管造影诊断为 NCS。她接受了保守治疗，肉眼血尿自发缓解。通过这个病例，我们想强调的是，对于血尿和直立性蛋白尿的儿童，如果没有明显的病因，高度怀疑和适当的影像学检查对于 NCS 的诊断是必要的。
