What imaging is typically used to evaluate PD catheter position when migration is suspected?

• A. Abdominal ultrasound and X-ray imaging to assess the catheter position.
• B. Blood tests for infection markers.
• C. CT without contrast is the standard.
• D. MRI is always required.

Answer: (A)

When assessing PD catheter position for suspected migration, the goal is to locate the catheter tip and trace its path inside the abdomen. The usual approach is abdominal ultrasound together with X-ray imaging. Ultrasound visualizes the catheter within the peritoneal cavity and can reveal if the tip has moved from the pelvis, become curled or tangled with omentum, or otherwise displaced, all without radiation. X-ray imaging provides a quick radiographic view of the catheter’s course and confirms the exact tip position relative to the pelvis and other structures, which helps determine if repositioning is needed. These tools are favored because they are fast, widely available, and give clear information to guide management. CT without contrast and MRI are not the standard first-line choices for this problem, and blood tests don’t show catheter position.
