What Is PCN in Urology | Sai Hospital, Haldwani

If you’ve ever seen the term PCN written on a urology prescription, ultrasound report, or doctor’s notes, it can feel confusing or even alarming. Patients often wonder what it means and whether it indicates a serious condition. In reality, PCN is a common and lifesaving procedure used in certain kidney problems.

At Sai Hospital, Haldwani, our urology team performs PCN regularly to relieve pain, protect kidney function, and treat urinary tract blockages. This article explains in simple terms what is PCN in urology, when it is needed, how it’s done, and what patients can expect before and after the procedure.

What Does PCN Mean in Urology?

In urology, PCN stands for Percutaneous Nephrostomy.
It is a minimally invasive procedure in which a small tube (called a nephrostomy tube) is inserted through the skin into the kidney to drain urine.

“Percutaneous” means through the skin, and “nephrostomy” means creating an opening in the kidney.

So, a PCN is essentially a kidney drainage procedure done when urine cannot flow normally from the kidney to the bladder.

Why Is PCN Done?

PCN is recommended when something blocks the urine flow in the urinary tract. If urine gets trapped inside the kidney, it causes swelling (hydronephrosis), pain, infection, and long-term kidney damage.

A PCN tube allows urine to drain directly from the kidney to a bag outside the body, giving immediate relief and preventing complications.

Common Reasons for Doing PCN:

1. Kidney Stones

Large stones can block the ureter (the pipe connecting kidney to bladder). PCN drains the urine and protects the kidney until the stone is treated.

2. Urinary Tract Obstruction

This may be due to:

• Ureter narrowing (stricture)
• Tumors in the pelvis or abdomen
• Prostate enlargement compressing the ureter
• Trauma

3. Severe Kidney Infection (Pyonephrosis)

In cases where pus collects in the kidney, PCN helps drain infected fluid quickly — a medical emergency.

4. Hydronephrosis with Severe Pain

PCN reduces pressure and pain instantly by allowing urine to escape.

5. Before Certain Urology Procedures

Sometimes PCN is placed first to stabilize the kidney before surgery or stone removal.

How Is PCN Performed?

At Sai Hospital, Haldwani, PCN is done by trained urologists or interventional radiologists with precision and patient safety in mind.

Step-by-Step Overview:

1. Local Anesthesia
   The patient’s back is numbed. Sedation may also be given for comfort.
2. Imaging Guidance
   Ultrasound or CT scan helps the doctor locate the correct part of the kidney.
3. Small Skin Opening
   A tiny puncture is made in the flank (side of the back).
4. Insertion of the Nephrostomy Tube
   A thin, flexible tube is guided into the kidney’s drainage system.
5. Fixing the Tube
   The tube is secured to the skin and connected to a drainage bag.
6. Monitoring
   Urine starts draining immediately, relieving pressure and pain.

Duration:

The entire procedure usually takes 20–40 minutes.

Is PCN Painful?

Most patients feel only mild pressure or discomfort during the procedure due to local anesthesia. After insertion, there may be temporary soreness at the tube site, which improves within a day or two.

Pain relief medications are provided as needed.

Risks and Side Effects of PCN

PCN is generally safe, but like any medical procedure, it carries some risks:

• Mild bleeding at the tube site
• Infection (rare, prevented with antibiotics)
• Tube dislodgement
• Urine leakage around the tube

At Sai Hospital, strict sterile techniques and expert handling minimize these complications.

Care After PCN Placement

Proper care ensures the tube works well and prevents infection.

Post-PCN Instructions:

• Keep the dressing clean and dry
• Avoid pulling or twisting the tube
• Empty the urine bag regularly
• Drink plenty of water unless advised otherwise
• Report fever, chills, or decreased urine output immediately

Regular follow-up is essential to monitor tube position and kidney function.

How Long Does a PCN Tube Stay In?

The duration depends on the underlying cause.

Typical duration:

• Few days to weeks for temporary blockages
• Longer periods in cancer-related obstructions
• Removed once the obstruction is treated (e.g., stone removal, stent placement)

Your urologist decides the right time to remove or replace the tube.

PCN vs DJ Stent: What’s the Difference?

Many patients confuse PCN with a stent.

Often, PCN is used in emergencies, and later a stent is placed as a long-term solution.

Benefits of PCN

• Immediate relief from pain and pressure
• Prevents permanent kidney damage
• Helps treat infections by draining pus
• Allows time for further treatment (stone surgery, stent placement)
• Safe for all age groups

At Sai Hospital, Haldwani, advanced imaging and expert team ensure high success rates for PCN with quick recovery.
