The Correct Option is A
Solution and Explanation
Step 1: Read the radiograph. The plain abdominal X-ray shows a curled radiopaque tube running along the course of the ureter with J-shaped ends.
Step 2: Identify the device. This is a ureteric stent, also called a double-J or retrograde ureteric stent. One curled end sits in the renal pelvis and the other in the bladder, keeping urine flowing from kidney to bladder.
Step 3: Reject the distractors. Surgical clips are small dense metallic markers, not long curled tubes. A Foley catheter sits in the bladder with a balloon, not coursing up the ureter. An intravesical wire would lie within the bladder only. The double-J appearance along the ureter confirms a stent.
