Kidney ultrasound for predicting kidney injury after heart bypass
Part of Heart & circulation, Kidney & urinary, Women’s health & pregnancy clinical trials.
This study looks at whether measuring blood flow in your kidneys with an ultrasound before surgery can help predict if you might develop kidney injury after your coronary bypass surgery. It's a way to see if your kidneys are more at risk so doctors can watch you more closely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older.
- You are having a planned (not emergency) coronary artery bypass surgery, and it will be done with a heart-lung machine (on-pump).
- This surgery is just the bypass – no other major heart procedures like valve repair at the same time.
- You have both kidneys, and you are not on dialysis.
- You are able to have an ultrasound (Doppler) of both kidneys before surgery, and the images need to be clear enough for measurements.

This trial tests if kidney ultrasound and urine oxygen levels can predict acute kidney injury after open heart surgery. It aims to help doctors catch kidney problems early.
This study uses ultrasound during heart bypass surgery to check blood flow in the new grafts and arteries. It aims to make sure the bypass is working well, which could help reduce complications.
This trial tests a new way of giving fluids during heart surgery that may help protect your kidneys. It looks at early signs of kidney stress to guide fluid management.
This study uses a simple ultrasound test (kidney artery scan) to see if it can predict kidney problems early in people who are very ill. It may help doctors protect your kidneys during your hospital stay.
This study looks for early signs in your blood or urine that can predict if you might develop kidney damage after heart or blood vessel surgery. It aims to help doctors identify high-risk patients earlier so they can protect their kidneys.
This study tests a technique used during planned heart bypass surgery to see whether it changes substances measured in urine that reflect kidney stress or injury. If you have upcoming elective bypass surgery, your team may collect blood and urine samples to study how your kidneys respond.
