Robotic-assisted combined transposition of left renal vein and gonadal vein as a novel treatment option for renal nutcracker syndrome: A case report

Renal nutcracker syndrome is a rare phenomenon that often causes various disability symptoms. The treatment protocol has been explored for a long time, but no consensus has been reached. PATIENT CONCERNS: Here, we report the case of a 19-year-old male suffering with nutcracker syndrome, including left-sided flank pain and intermittent gross hematuria. DIAGNOSES: The patient was diagnosed with renal nutcracker syndrome, and the pressure gradient between the left renal vein and inferior vena cava was >5 mm Hg. INTERVENTIONS: The patient underwentrobotic-assisted combined transposition of left renal vein and gonadal vein. OUTCOMES: Flank pain and gross hematuria ceased spontaneously after surgery without occurrence. LESSONS: Robotic-assisted combined transposition of the left renal vein and gonadal vein is a safe and promising option for this condition.
