: CT-Guided Pelvis Drainage Catheter Replacement

: What This Procedure Is

: A drainage catheter is a thin, flexible tube used to remove fluid that has collected in the pelvis, such as an abscess or other fluid collection. Over time, a catheter may need to be exchanged or replaced. CT-guided replacement means your care team uses CT imaging during the procedure to see the catheter and surrounding tissues in real time and place the new catheter accurately.

: Why It May Be Done

: Your care team may recommend replacing the catheter if it becomes blocked, dislodged, or no longer drains well, or if the original catheter needs to be exchanged as part of your ongoing treatment. CT guidance is used when precise placement is important because of the location of the fluid collection or nearby organs and blood vessels.

: What to Expect

: The procedure is typically performed by a specially trained radiologist, often with sedation or local numbing medicine to keep you comfortable. You will lie on a CT table while images are taken to plan the catheter position. The old catheter is removed and a new one is placed, and imaging is used to confirm the new catheter is in the right position. Your care team will give you specific instructions about eating, drinking, and medications beforehand.

: After the Procedure

: You will be monitored for a short time afterward. The catheter site is checked for bleeding or leakage, and you may receive instructions on how to care for the catheter at home, including keeping the area clean and watching for signs of infection. Your care team will tell you when follow-up imaging or a clinic visit is needed.
