Robotic-assisted left renal vein transposition with distal gonadal vein anastomosis: A novel technique for dual venous drainage in nutcracker syndrome.

ABSTRACT:

Objective

To evaluate the feasibility and outcomes of a novel robotic-assisted laparoscopic technique-Di's II robotic-assisted left renal vein (LRV) transposition with distal gonadal vein (GV) anastomosis-creating dual venous drainage for treating nutcracker syndrome (NCS).

Methods

Between December 2023 and October 2024, three male patients (median age, 14 years) with NCS underwent robotic-assisted LRV transposition using the Di's II technique. Key procedural innovations included selective occlusion of the infrarenal inferior vena cava (IVC) and LRV without right renal vein clamping, combined with distal GV anastomosis to enhance venous drainage. Operative parameters, including anastomosis time, blood loss, and postoperative outcomes, were analyzed retrospectively.
