-
Compression of the left renal vein between the superior mesenteric artery and the abdominal aorta causing an increase in the pressure gradient between the left renal vein and the inferior vena cava. The thin septae between the veins and the collecting system in the renal fornices rupture, with resultant left sided haematuria. Most symptomatic cases present in the third or fourth decade of life, with women being more commonly affected than men. Three types of renal nutcracker syndrome have been defined: anterior nutcracker syndrome, posterior nutcracker syndrome and combined nutcracker syndrome.
