Robot-assisted renal autotransplant for nutcracker syndrome following unsuccessful renocaval bypass.

The nutcracker phenomenon results from a rare anatomic abnormality where the left renal vein (LRV) is compressed by the aorta and superior mesenteric artery. Nutcracker syndrome (NCS) is defined by the constellation of symptoms that may develop, which includes haematuria, pelvic pain and venous congestion. We present a case of an otherwise healthy woman in her early 40s with NCS with a failed initial attempt at LRV to inferior vena cava bypass grafting, with subsequent successful treatment via robot-assisted left renal autotransplantation.
