USG KUB

You should get a USG KUB if you have flank or lower back pain, burning or frequent urination, blood in the urine, recurrent urinary infections, or difficulty passing urine. It is also recommended for abnormal kidney function tests, suspected kidney stones, prostate enlargement in men, and for monitoring chronic kidney disease or known kidney cysts.

Fasting is usually not required for a USG KUB, though some centers advise a light meal to reduce gas. About 1 hour before the scan, drink 4–6 glasses of water and don’t urinate, as a full bladder is needed. You may be asked to empty your bladder later to check residual urine. Wear loose clothing and bring previous reports.

No, fasting is usually not required for a USG KUB. You can eat a light meal, though some centers may advise a short fast to reduce gas. The most important step is to arrive with a full bladder, so drink 4–6 glasses of water about 1 hour before the scan and avoid urinating.
