Final answer:
The upper urinary tract includes the kidneys and ureters, while the lower urinary tract includes the bladder and urethra. Imaging techniques such as ultrasound, CT scan, MRI, cystoscopy, and voiding cystourethrography are used to visualize and evaluate these areas.
Step-by-step explanation:
The upper urinary tract includes the kidneys and the ureters, while the lower urinary tract includes the bladder and the urethra. Imaging the upper urinary tract typically involves techniques such as ultrasound, CT scan, or MRI.
These imaging modalities can provide detailed images of the kidneys and ureters and can help identify any abnormalities or conditions.
Imaging the lower urinary tract usually involves techniques such as cystoscopy or voiding cystourethrography.
Cystoscopy uses a thin tube with a camera to examine the bladder and urethra from the inside, while voiding cystourethrography involves injecting a contrast dye into the bladder and then taking X-ray images as the patient urinates to evaluate the function and structure of the bladder and urethra.
