X-ray of the urinary bladder, ureters, and renal pelvis after dye is inserted through the urethra is called?

• A. Retrograde pyelogram
• B. PSA
• C. Phimosis
• D. Sexually transmitted disease

Answer: (A)

This describes a retrograde pyelography. In this test, contrast dye is injected through the urethra via a catheter and guided upward through the bladder into the ureters and renal pelvis. The contrast outlines the collecting system, allowing X-ray images of the bladder, ureters, and renal pelvis to assess for stones, strictures, tumors, or other obstruction. It’s used when direct visualization of the ureters is needed or when intravenous contrast imaging isn’t suitable. The other terms don’t fit: PSA is a blood test for prostate conditions, phimosis is a foreskin condition, and sexually transmitted diseases are infections, none of which describe this imaging procedure.
