Robotic assisted kidney auto-transplantation as a safe alternative for treatment of nutcracker syndrome and loin pain haematuria syndrome: A case series report

Abstract

Background: Describe the outcomes and safety of robotic-assisted kidney auto-transplantation (RAKAT) in the treatment of nutcracker syndrome (NCS) and loin pain haematuria syndrome (LPHS). Methods: This retrospective study included 32 cases of NCS and LPHS seen during December 2016 to June 2021. Results: Three (9%) patients had LPHS and 29 (91%) NCS. All were non-Hispanic whites, and 31 (97%) women. The mean age was 32 years (SD = 10) and the BMI 22.8 (SD = 5). The RAKAT was completed in all patients, 63% had a total improvement of pain. According to the Clavien-Dindo classification, 47% presented with type 1, and 9% with type 3 complications with a mean follow-up of 10.9 months. The incidence of acute kidney injury in post-procedure was 28%. No one required blood transfusions, and there were no deaths during the follow-up. Conclusion: RAKAT was a feasible procedure with a similar complication rate to those reported for other surgical techniques.
