An Ultrasound of the Kidneys, Ureters, and Bladder (KUB) is a non-invasive imaging test used to assess the urinary tract. It helps identify kidney stones, bladder abnormalities, structural changes, and signs of infection. Doctors commonly recommend this scan for individuals experiencing abdominal pain, difficulty in urination, or frequent urinary infections. It uses safe sound wave technology to create real-time images, without any radiation exposure, making it suitable for all age groups.
