The term cystourethrography refers to the radiologic examination of which structures?

• A. Kidneys and ureters
• B. Urinary bladder and urethra
• C. Prostate and bladder
• D. Urethra and renal pelvis

Answer: (B)

Cystourethrography specifically involves the radiologic examination of the urinary bladder and urethra. During this procedure, a contrast medium is introduced into the bladder through a catheter, which allows for detailed imaging of its structure and any potential abnormalities in both the bladder and urethra.

This examination is particularly valuable in diagnosing conditions such as bladder stones, tumors, or strictures in the urethra, and it provides insights into the functional aspects of these parts of the urinary system. The focus on the bladder and urethra is evident from the name of the procedure itself, as it combines "cysto" (referring to the bladder) and "urethro" (referring to the urethra), indicating a targeted assessment of these two specific structures.
