- Abstract
Objective: Nutcracker syndrome is a rare condition that involves mechanical compression of the left renal vein, leading to chronic and debilitating left flank pain. The etiology of the pain is misdiagnosed frequently, and patients usually require long-term opioid use to manage their pain. Multiple therapeutic options for nutcracker syndrome have been described in the literature but the reports are limited by small numbers of patients, and the lack of convincing data demonstrating consistently improved outcomes. Here we report the largest series to date of patients undergoing renal autotransplantation for the treatment of nutcracker syndrome., Methods: We performed a multicenter retrospective cohort review of patients 105 patients with nutcracker syndrome who underwent renal autotransplantation as a primary or salvage therapy., Results: During the overall study period, 93.1% of patients treated with autotransplantation had durable, complete flank pain relief at 12 months with both open and robotic surgical approach. After autotransplantation, a statistically significant decrease in the percentage of patients using opioids from 48.6% to 17.0% was demonstrated at 12 months. In those patients using opioids before autotransplantation, a statistically significant decrease in morphine milligram equivalents was demonstrated from an alarming 68.9 ± 15.0 per day to 25.0 ± 11.02 morphine milligram equivalents per day., Conclusions: Our findings suggest that renal autotransplantation, as a primary treatment or a salvage treatment, in patients with nutcracker syndrome provides durable pain relief and a marked decrease in chronic opioid use regardless of surgical approach., Competing Interests: Disclosures None., (Copyright © 2024 The Author(s).
