- Design
- Randomised, open-label, single-centre trial
- Population
- 107 adults with end-stage kidney disease (106 transplanted)
- Primary outcome
- 30-day major surgical and vascular complications
- Effect
- Major complications 13% vs 25% (RD -11%, -26 to 3.4); vascular 9.4% vs 19%
ORAKTx randomised adults with end-stage kidney disease at a single Danish centre to robot-assisted or open kidney transplantation; 106 underwent transplant and completed follow-up.
Major surgical complications at 30 days occurred in 13% with robotic surgery and 25% with open surgery (risk difference -11%, 95% CI -26% to 3.4%). Vascular complications were 9.4% versus 19% (difference -9.4%, -23% to 3.7%). Neither primary outcome reached significance.
The trial was small and open-label. The direction favours robotics, but the intervals include no difference, so it is a reason for a larger trial rather than a change in practice.
- Open kidney transplantation remains the standard outside expert robotic centres
- Robotic transplantation may reduce complications, but this is unproven
- Consider robotic transplantation within trials or audited programmes
- Wound complications in obese recipients are the plausible target for robotics
Why it matters
It is the first randomised comparison in a field adopting robotics on observational data.
Don't overread it
The primary endpoints were not met; a 107-patient single-centre trial cannot establish benefit.
The statistics, in plain English
A risk difference of -11% with an interval from -26% to +3.4% means the data are compatible with a large benefit or a small harm.
