Non-Right Renal Vein Occlusion: A Side Clamp Two-Step Technique for Robot-Assisted Laparoscopic Transposition of the Left Renal Vein in Nutcracker Syndrome
Objective
To evaluate the feasibility of a novel robotic-assisted laparoscopic technique—side clamp two-step vascular method—for left renal vein (LRV) transposition in nutcracker syndrome (NCS).
Methods
Between May and December 2023, three male NCS patients (median age: 14 years) underwent robot-assisted LRV transposition using the Di's technique. The key procedure included a side clamp two-step technique to selectively occlude the infrarenal inferior vena cava and LRV without right renal vein manipulation. Surgical outcomes, including operative time, blood loss, anastomosis duration, and postoperative complications, were retrospectively analysed.
Results
All procedures were successfully completed. Median operative time was 125 min, with LRV anastomosis completed in 23 min. Postoperative imaging confirmed the resolution of LRV compression, with pressure gradients reduced to < 3 mmHg. Symptoms resolved completely within 4 weeks.
Conclusions
The robotic-assisted side clamp two-step technique offers a minimally invasive alternative for LRV transposition in NCS, minimising vascular dissection and preserving right renal venous flow.
Trial Registration
This clinical trial has been registered in the Chinese Clinical Trial Registry (ChiCTR, registration number: ChiCTR2500099335).
期刊介绍：
The International Journal of Medical Robotics and Computer Assisted Surgery provides a cross-disciplinary platform for presenting the latest developments in robotics and computer assisted technologies for medical applications. The journal publishes cutting-edge papers and expert reviews, complemented by commentaries, correspondence and conference highlights that stimulate discussion and exchange of ideas. Areas of interest include robotic surgery aids and systems, operative planning tools, medical imaging and visualisation, simulation and navigation, virtual reality, intuitive command and control systems, haptics and sensor technologies. In addition to research and surgical planning studies, the journal welcomes papers detailing clinical trials and applications of computer-assisted workflows and robotic systems in neurosurgery, urology, paediatric, orthopaedic, craniofacial, cardiovascular, thoraco-abdominal, musculoskeletal and visceral surgery. Articles providing critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies, commenting on ease of use, or addressing surgical education and training issues are also encouraged. The journal aims to foster a community that encompasses medical practitioners, researchers, and engineers and computer scientists developing robotic systems and computational tools in academic and commercial environments, with the intention of promoting and developing these exciting areas of medical technology.
