Using kidney Doppler and urine oxygen to predict acute kidney injury after open heart surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Cardiac surgery-associated acute kidney injury (CSA-AKI) occurs in about 15–30% of patients after open heart procedures and is linked to higher morbidity, mortality, and longer hospital stays. This observational cohort will record renal resistive index (RRI) and renal artery pulsatility index (RAPI) by Doppler ultrasound alongside urinary oxygen partial pressure before, during, and after elective on-pump cardiac surgery. Investigators will correlate those measurements with postoperative development of AKI to determine their predictive value. The aim is to see if these noninvasive bedside measures can identify patients at imminent risk of kidney injury.
