USG-Guided Abscess Drainage / Catheter Placement
What is a USG-guided abscess drainage or catheter placement procedure?
A USG-guided abscess drainage is a minimally invasive procedure done under ultrasound guidance to remove pus or infected fluid collected in any part of the body.
When continuous drainage is required, a catheter (thin flexible tube) is placed into the abscess cavity under ultrasound control to allow the pus to drain out over a few days.
At Mitra Diagnostics, this procedure is performed by experienced interventional radiologists using real-time ultrasound imaging for safe and precise placement.

Why is this procedure needed?
Your doctor may recommend this procedure if:
- You have an abscess (pus collection) in the liver, kidney, pelvis, abdomen, chest wall, or soft tissues
- Antibiotics alone are not resolving the infection
- Imaging (CT or ultrasound) shows a localized fluid collection.
- To relieve pain, swelling, and fever caused by infection
- To avoid open surgical drainage and promote faster recovery.
How does ultrasound guidance help?
Ultrasound provides real-time imaging of the abscess and surrounding organs.
This allows the radiologist to:
- Choose the safest route for needle or catheter insertion
- Avoid injury to nearby blood vessels or organs
- Ensure complete and accurate drainage

More Frequently Asked Questions
Is the procedure painful?
No, it is usually not painful.
- – A local anaesthetic is given to numb the skin.
- – You may feel mild pressure or discomfort when the catheter is inserted, but no sharp pain.
- – The procedure is generally well-tolerated and much less painful than surgery.
How is the procedure performed?
- You’ll lie comfortably on the scan table.
- The skin over the affected area is cleaned and sterilized.
- Under ultrasound guidance, a small needle is inserted into the abscess.
- The pus or fluid is aspirated (removed) and sent for laboratory culture.
- If continuous drainage is required, a catheter is placed and connected to a drainage bag.
- The catheter is secured and covered with sterile dressing.
Is hospital admission required?
- – Many cases can be done as a day-care procedure.
- – If the infection is severe or catheter drainage is required for several days, short hospital admission may be advised for observation and antibiotics.
How long does the catheter stay in place?
- – Usually for 2–5 days, depending on the amount of pus and the healing progress.
- – The catheter is removed once the drainage stops and follow-up ultrasound confirms resolution.
Are there any risks or side effects?
USG-guided drainage is very safe, but rarely:
- – Mild pain or bruising at the puncture site
- – Minimal bleeding or leakage around the catheter
- – Infection at the insertion site (prevented with sterile precautions)
All procedures at Mitra Diagnostics are done under strict aseptic conditions to minimize any risk.
What are the benefits of USG-guided drainage compared to surgery?
- – Minimally invasive (no large cut or stitches)
- – Faster recovery and shorter hospital stay
- – Less pain and scarring
- – Lower cost than surgery
- – Can be done under local anaesthesia
- – Accurate and safe due to real-time imaging
Can the drained fluid be tested?
Yes.
The collected fluid or pus is sent to the laboratory for:
- – Culture and sensitivity test (to identify bacteria and choose the best antibiotic)
- – Cytology or biochemistry (if required for diagnosis)
What care is needed after the procedure?
- – Keep the catheter site clean and dry.
- – Do not tug or twist the drainage tube.
- – Report any fever, redness, or increased pain to your doctor.
- – Continue prescribed antibiotics and follow-up scans as advised.
When will I get my report?
- – An ultrasound report describing the abscess and procedure details is provided immediately after the procedure.
- – Fluid culture reports take 2–3 days depending on the lab results.
Summary
USG-guided abscess drainage or catheter placement is a safe, minimally invasive alternative to surgery for removing infected fluid collections.
At Mitra Diagnostics, we perform this under expert supervision, ensuring precision, safety, and faster healing.
