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

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). This retrospective study included 32 cases of NCS and LPHS seen during December 2016 to June 2021. 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. RAKAT was a feasible procedure with a similar complication rate to those reported for other surgical techniques.
