Purpose:
To describe a single-center experience with robotic-assisted endovascular treatment for transplant renal artery stenosis.
Materials And Methods:
This is a single-center, retrospective, feasibility study of 4 consecutive cases of robotic-assisted endovascular surgery for transplant renal artery stenosis from October 2021 to August 2022.
Results:
All lesions were identified, and stenting was performed with no complications. Conversion to manual control was not necessary. The mean fluoroscopy time was 25.25 min (range 12-60.9). A control Doppler ultrasound was routinely performed, demonstrating no residual lesions in all cases. There was no reintervention during the follow-up period. The operator learning curve was felt to be acceptable.
Conclusion:
Robotic-assisted endovascular treatment is a feasible technique for transplant renal artery stenosis.
