Abstract :
A 58-year-old man presented with severe hematuria of unknown origin and intermittent left flank pain for 8 months, and he was diagnosed with posterior nutcracker syndrome. He underwent prosthetic left renocaval bypass with complete resolution of symptoms. Computed tomography showed a functional graft between the left renal vein and caval vein. This technique is a feasible choice for surgical treatment of posterior nutcracker syndrome with satisfactory results.

Case :
A 58-year-old man presented with severe hematuria and intermittent left flank pain for 8 months. The pain occurred about three times every week, and every attack lasted for 40 min. His medical history and findings on physical examination were unremarkable with a body mass index of 19.4 kg/m2. The urinalysis was positive for hematuria, and the hemoglobin level was 10.5 g/L (105 g/L). Computed tomography angiography (CTA) showed the presence of a retro-aortic LRV, and CTA also confirmed compression of the LRV by the abdominal aorta and the vertebral body (Fig. 1). Cystoscopy revealed bleeding from the left ureteral orifice. He received conservative treatment for 7 months, and the condition did not improve.......
