When a kidney cannot drain because the urinary tract is blocked, urine backs up, pressure builds inside the kidney, and — if there is infection — it can quickly become life-threatening. A percutaneous nephrostomy in Delhi (PCN) solves this fast: a thin drainage tube is placed through the skin directly into the kidney under imaging guidance, releasing the trapped urine and protecting the kidney. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, this minimally invasive, image-guided procedure is performed to relieve blocked and infected kidneys.
This guide explains what a percutaneous nephrostomy is, when it is needed, how it is done, and what living with a nephrostomy tube involves.

What Is a Percutaneous Nephrostomy (PCN)?
Percutaneous nephrostomy is an image-guided procedure in which a fine catheter (nephrostomy tube) is inserted through the skin of the back directly into the kidney’s collecting system. It creates a new route for urine to drain out of the body into a collection bag, bypassing whatever is blocking the normal path. Because it is guided by ultrasound and X-ray (fluoroscopy) or CT, the tube is placed precisely through a small puncture — no open surgery is required.
Why and When Is a Nephrostomy Needed?
A nephrostomy is usually needed when the ureter (the tube from kidney to bladder) is blocked and the kidney cannot drain. Common reasons include:
- Kidney or ureteric stones blocking the flow of urine
- Tumours (of the ureter, bladder, prostate, cervix or other pelvic organs) pressing on or invading the ureter
- Strictures (narrowing) of the ureter
- Infected, obstructed kidney (pyonephrosis) — a medical emergency where pus and urine are trapped, risking sepsis
- Urinary leaks or the need to divert urine after injury or surgery
- Access for further treatments such as stone removal or ureteric stenting
Draining the kidney quickly relieves the back-pressure, preserves kidney function, and controls infection.
Why Image Guidance Makes It Safe
A nephrostomy must reach the exact part of the kidney’s collecting system while avoiding blood vessels, the bowel, lung and other organs. Ultrasound and fluoroscopic (or CT) guidance let the radiologist see the needle and the target in real time, so the tube is placed accurately through the safest path. This precision is what makes the procedure both effective and low-risk. At Edge, PCN is performed as part of our interventional radiology services, supported by high-resolution ultrasound and CT.
How the Nephrostomy Procedure Works
The procedure is carried out with the patient usually lying face-down, and takes around 30–60 minutes:
- Imaging & planning: the blocked kidney is assessed on ultrasound/CT and the safest entry point chosen.
- Cleaning & anaesthesia: the skin of the back is cleaned and numbed with local anaesthetic; sedation may be given.
- Needle access: under live imaging, a fine needle is guided into the kidney’s collecting system.
- Tube placement: a guidewire is passed, the track is gently widened, and a self-retaining pigtail catheter is coiled inside the kidney.
- Drainage: the tube is secured to the skin and connected to a drainage bag; urine begins to drain immediately.
Living With a Nephrostomy Tube
The nephrostomy tube drains urine into a bag attached to your side or leg. Simple care keeps it working well: keep the tube and dressing clean and dry, avoid kinking or pulling on it, empty the bag regularly, and watch for signs of blockage or infection (fever, reduced drainage, pain). The tube is a temporary or medium-term measure while the underlying cause is treated, and it needs to be changed periodically. Our team explains all aftercare clearly before you go home.
Is a Nephrostomy Painful or Risky?
The procedure is done under local anaesthesia (often with sedation), so most patients feel only pressure during placement. Afterwards, mild soreness at the tube site is common and easily managed. It is a well-established, safe procedure; uncommon risks such as bleeding or infection are minimised by image guidance and sterile technique. For an infected, obstructed kidney, the relief a nephrostomy provides can be life-saving.

Frequently Asked Questions
Is a nephrostomy an emergency procedure?
It can be. An infected, obstructed kidney (pyonephrosis) needs urgent drainage to prevent sepsis. In other cases it is planned to relieve a blockage and protect kidney function.
Is the nephrostomy procedure painful?
It is done under local anaesthesia, often with sedation, so most people feel only pressure. Mild soreness afterwards is easily managed with simple pain relief.
How long does a nephrostomy tube stay in?
It varies — the tube stays until the underlying blockage is treated, which may be days, weeks or longer. It is changed periodically while in place.
Can I go home with a nephrostomy tube?
Yes. Most patients go home with the tube and a drainage bag, after being shown how to care for it. Follow-up is arranged for tube changes and further treatment.
Will a nephrostomy affect my kidney?
On the contrary — by relieving the blockage quickly, a nephrostomy protects the kidney from pressure damage and helps preserve its function.
How much does a nephrostomy (PCN) cost in Delhi?
The cost depends on whether ultrasound or CT guidance is used and the clinical situation. Edge Imaging offers transparent pricing — call 9555999960 for details. Nephrostomy is often covered by health insurance as a medically necessary procedure.
