About this study
Official title: The Use of Urinary MALDI-MS in Predicting Post-Operative Acute Kidney Injury in Patients After Fixation of Fractured Neck of Femur.
To determine whether MALDI, a type of Mass-Spectometry, can use protein pattern detection within urine to predict postoperative (after an operation) kidney damage in adults who have undergone emergency hip fracture surgery?
Read the detailed description
The PRE-RENAL study is a prognostic accuracy study testing the ability of the MALDI-MS assay to predict incident acute kidney injury after fractured neck of femur surgery. The study aims to validate the findings of a urinary peptide panel previously developed and validated on a cohort of septic patients.
Kidney injury following surgery or as a part of severe illness is an important complication, because it can delay and reduce the chances of recovery. A reliable early test for kidney injury would be useful so that treatments to prevent or minimise it can be started as early as possible. This study, based with a group of medical researchers working with chemists, will analyse clinical urine specimens from patients undergoing major orthopaedic (bone) surgery. We will explore whether patterns of proteins in the urine could be used as an early warning that kidney injury is present before existing tests demonstrate it.

Questions about this trial
What is this clinical trial studying?
An observational study of Acute Kidney Injury, run by University of Edinburgh at 1 site in United Kingdom.

Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 May 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Acute Kidney Injury (time frame: Within 7 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 May 2024; AzTrials last refreshed its copy on 8 Nov 2026.
