This clinical trial focuses on people with end-stage kidney disease ESKD who are preparing for nonemergent surgical procedures. The study aims to evaluate whether it is feasible and safe to assign participants randomly to one of two hemodialysis schedules before surgery having hemodialysis on the same day as surgery or not. Researchers want to compare these schedules to see if they are similar in terms of scheduling feasibility and safety. Participants will be assigned to either receive hemodialysis on the morning of their surgery day or not receive hemodialysis on that same day. The study uses these two groups to compare the effects and safety of the timing of hemodialysis before surgery. The study period for each participant lasts about two months, including the time before and after surgery. During the study, participants will answer health-related questions up to four weeks before and four weeks after surgery. Researchers will monitor the time between the last hemodialysis session and surgery, as well as any complications such as electrolyte problems, volume overload requiring extra hemodialysis, surgery rescheduling, or higher levels of postoperative care. The study team will carefully observe these outcomes for up to one day after surgery.

This table compares participation in this trial with other options available for this condition. The information is drawn from published research and the trial’s study details and is provided for educational purposes only.
| Factors | Hemodialysis on the day of surgery | No hemodialysis on day of surgery |
|---|---|---|
| What is it? | Hemodialysis is performed on the same calendar day as the surgical procedure, typically in the morning just prior to surgery. | Hemodialysis is not performed on the same day as the surgical procedure; the last session occurs at least a day before surgery. |
| Role in this study | Investigational intervention arm; tests the effects of receiving hemodialysis on the same day as surgery. | Comparator arm; evaluates outcomes when hemodialysis is scheduled on a day before the operation. |
| Primary use in clinical care | Ensures immediate preoperative fluid and electrolyte control for patients with end-stage kidney disease. | Follows traditional practice in which hemodialysis is delivered one or more days before surgery to balance dialysis benefits and avoid potential risks of same-day treatment. |
| How is it performed? | Participants undergo hemodialysis on the morning of the scheduled surgery under a stable outpatient regimen. | Participants do not receive hemodialysis on the day of surgery; the last session occurs prior to the calendar day of surgery as part of usual maintenance. |
| Evidence status | This approach is being actively studied in ongoing trials. External studies have shown associations between the timing of preoperative dialysis and postoperative outcomes, but definitive randomized evidence is still limited. | This schedule reflects prevailing practice, mainly supported by observational studies. The most recent studies link earlier preoperative dialysis to varying outcomes, but the optimal timing remains under debate. |
| Important limitations | Randomized evidence is limited and there are logistical challenges with preoperative same-day dialysis scheduling and urgent changes in surgery timing. | Evidence for this approach stems mainly from retrospective and observational studies, which may be affected by confounding and do not always control for all patient factors. |
