Guiding blood flow management during major abdominal surgery using urethral perfusion index
Official title: Urethral PeRfusion Index-Guided Hemodynamic ManagemenT in Patients Having Major Abdominal Surgery: the UPRIGHT Randomized Feasibility Trial
Run by Universitätsklinikum Hamburg-Eppendorf · NCT06799832 · Data updated 2026-11-12
This study is testing if keeping track of blood flow in the urethra during major abdominal surgery can help improve overall blood flow to the body compared to regular care.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients aged 45 and older scheduled for elective major abdominal surgery requiring arterial and urinary catheters.
✕Probably not a fit
Patients who are pregnant, undergoing nephrectomy or organ transplantation, or those with prior urethral or bladder surgery may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This pilot trial aims to evaluate whether maintaining a specific urethral perfusion index during major abdominal surgery can improve tissue perfusion compared to standard care. The study will monitor urethral perfusion in patients undergoing elective surgeries lasting at least 120 minutes and will assess the correlation between urethral perfusion index and other vital signs. Additionally, it will explore the relationship between urethral and peripheral perfusion indices. The trial is conducted at a single center, focusing on a specific patient population.
Why it matters
Potential benefit: If successful, this approach could enhance patient outcomes by optimizing blood flow management during major surgeries.
How similar studies have gone: While this specific approach is novel, similar studies have explored perfusion monitoring in surgical settings with varying degrees of success.
