Objective:
To describe the feasibility of retroperitoneal laparoscopic reimplantation of the left renal vein (LRV) for nutcracker syndrome (NCS).
Patients And Methods:
Two patients with NCS underwent the surgery. Both patients complained of gross hematuria and flank discomfort that could not be relieved by resting. They were placed in a supine position and 5 ports were placed in the right abdominal wall. The procedures were performed with a retroperitoneal approach. The LRV was transected and then reimplanted into the distal inferior vena cava.
Results:
The procedures were performed successfully without any major complications. The total operation time was 105 and 120 min, respectively. Hematuria and flank discomfort were resolved after the surgery. Ultrasonography revealed a patent lumen without compression.
Conclusions:
Retroperitoneal laparoscopic reimplantation of the LRV appears to be a feasible procedure with satisfactory short-term outcomes.
