What is Nephrostomy?
A nephrostomy is a medical procedure in which a small tube, called a nephrostomy tube, is inserted through the skin into the kidney to drain urine directly. It is usually done when there's a blockage in the urinary tract that prevents urine from flowing naturally into the bladder.
This procedure helps relieve pressure in the kidney, prevent infections, and protect kidney function. Nephrostomy may be temporary, used until the blockage is cleared, or long-term, depending on the underlying condition. It's often guided by ultrasound or CT imaging to ensure precision and safety.
Types of Nephrostomy
Nephrostomy can be temporary or permanent, depending on the underlying condition, and may be guided by ultrasound or fluoroscopy.
- Temporary Nephrostomy: This is done when the obstruction is anticipated to be temporary as in a kidney stone or post-surgery swelling. As soon as the background problem is addressed, the tube can be removed safely.
- Permanent (Long-Term) Nephrostomy: A permanent nephrostomy can be done in situations where the urinary blockage is not correctable or the kidney requires permanent drainage. This option may be needed in patients with a complicated urinary tract or advanced cancer.
- Unilateral Nephrostomy: This involves placing a nephrostomy tube in one kidney only, typically when the blockage affects just one side of the urinary system.
- Bilateral Nephrostomy: Here, tubes are placed in both kidneys, usually when both sides are blocked or when kidney function needs extra protection.
- Image-Guided Nephrostomy: Using ultrasound or CT guidance, doctors place the tube with high accuracy, minimising risks and ensuring proper drainage. This is the most common method today.

When is Nephrostomy Recommended?
A nephrostomy is a procedure that is typically indicated when the regular urine flow between the kidney and the bladder is compromised or blocked, and urgent drainage is necessary to preserve the functionality of the kidney.
Here are the common reasons:
- Urinary Tract Obstruction: Conditions like kidney stones, tumors, or scar tissue can block the ureters, preventing urine from draining properly. A nephrostomy provides an alternative pathway until the blockage is treated.
- Hydronephrosis (Swelling of the Kidney): When urine builds up inside the kidney due to an obstruction, it can cause pain, swelling, and damage. A nephrostomy relieves the pressure and preserves kidney health.
- Cancer-Related Blockages: Cancers of the bladder, cervix, prostate, or colon may press on or invade the urinary tract. Nephrostomy helps in bypassing these blockages to maintain urine flow.
- Severe Infections (Pyonephrosis): If pus collects inside the kidney due to an infection, immediate drainage with a nephrostomy is essential to prevent sepsis and further complications.
- Post-Surgical or Injury-Related Issues: In some instances following pelvic or abdominal operation or trauma, the urinary tract can be obstructed or destroyed. Temporarily, urine drainage can be maintained by a nephrostomy.
- Congenital Abnormalities: There are rare instances when children or newborns might experience birth defects to be unable to urinate normally. Until the repair surgery is done, a nephrostomy will help alleviate pain.
Preparing for Nephrostomy Surgery Procedure
Preparing for your Nephrostomy surgery is a key part for a smooth surgery and a fast recovery.
Medical Evaluation & Pre-Procedure Tests
Your doctor will examine your medical history, medications that you are using, and conditions that you may have like diabetes, heart disease, or bleeding disorders. Regular tests such as blood tests, urine tests and imaging (ultrasound, CT or MRI) are conducted to monitor the functionality of the kidneys besides determining the precise site of the obstruction.
Medication Adjustments
Some drugs, in particular, blood thinners (aspirin or clopidogrel) should be discontinued several days before the procedure to minimize the chances of bleeding. The first action is to always speak to your doctor about your medication list before you change or stop taking any medication.
Fasting Before the Procedure
Patients are usually advised not to eat or drink anything for 6-8 hours before the nephrostomy. This is important for safety during anesthesia or sedation.
Infection Control
If there are signs of infection, your doctor may prescribe antibiotics before the procedure to minimize the risk of complications. In some cases, antibiotics are given just before the nephrostomy as a preventive measure.
Consent & Patient Counseling
Your doctor will explain the benefits, risks, and alternatives of the nephrostomy. This is the time to ask questions and clear any doubts. Signing the consent form ensures you fully understand the procedure.
Practical Preparation at Home
Arrange for someone to accompany you to the hospital and drive you back home if it's a planned procedure. Also, prepare loose-fitting clothes, and ensure your home environment is comfortable for a few days of recovery.
What Happens During Nephrostomy Surgery?
During the procedure, a catheter is inserted into the kidney through the skin to drain urine, usually under local anesthesia and imaging guidance.
- Preparation & Anesthesia: Once you're in the procedure room, your medical team will confirm your identity, review your test results, and explain the steps one more time. Depending on your condition, you may receive local anesthesia (to numb the area), sedation (to help you relax), or general anesthesia (in complex cases).
- Positioning & Cleaning the Area: You will be asked to lie on your stomach or slightly on your side so the doctor can easily access your kidney. The skin over your back is cleaned thoroughly with antiseptic solution to minimize infection risk, and sterile drapes are placed.
- Imaging Guidance: Using ultrasound or fluoroscopy (real-time X-ray imaging), the doctor locates the exact position of the kidney and the site of the blockage. This ensures precise needle placement and minimizes damage to surrounding tissues.
- Needle Insertion & Accessing the Kidney: A fine needle is carefully inserted into the kidney under imaging guidance. Once the correct placement is confirmed, a guidewire is passed through the needle to create a safe path for the tube.
- Catheter Placement: A thin, flexible tube called a nephrostomy catheter is then threaded over the guidewire and positioned inside the kidney. This tube allows urine to drain directly from the kidney into a collection bag attached outside the body.
- Securing the Tube: The catheter is stitched or taped securely to your skin to prevent movement or accidental dislodging. A sterile dressing is applied to keep the site clean and protected.
- Immediate Monitoring: Once the nephrostomy tube is in place, urine drainage is checked to ensure the kidney is functioning properly. You will be moved to a recovery area for monitoring of vital signs, urine output, and comfort level.
Who Perform the Nephrostomy Procedure?
A nephrostomy is a medical procedure that involves creating a temporary or permanent opening in the kidney through the skin, allowing urine to bypass any obstruction in the normal urinary pathway. Nephrostomy tubes are placed in the kidney to drain urine directly from the renal pelvis into an external collection bag.
Interventional radiologists or urologists typically do nephrostomy tube placement and management. These medical professionals have specialized training in imaging techniques and surgical procedures to treat kidney and urinary tract issues.
The choice between interventional radiologists and urologists may depend on the specific circumstances of the patient, the hospital's resources, and the availability of specialists.
Recovery After Nephrostomy Surgery Procedure
Recovering from a Nephrostomy is a step-by-step process, and real care makes all the difference.
First Few Days After Procedure
- You may feel mild soreness or discomfort around the tube insertion site. This is normal and usually improves in a few days.
- The nephrostomy tube will be connected to a drainage bag. Nurses will teach you how to handle it safely and keep it clean.
- Walking gently and sitting upright helps improve circulation and prevents complications.
- Avoid pulling, bending, or putting pressure on the tube area to prevent dislodgement.
Doctor's Tip: Don't be alarmed if urine looks bloody at first, it usually clears within a few days.
Weeks 1 to 2
- The area around the tube may remain a little tender, but swelling and redness should gradually reduce.
- Tube care becomes part of your daily routine, flushing (if advised), emptying the drainage bag, and keeping the site clean.
- You may resume light activities but avoid strenuous work, lifting, or twisting movements.
Doctor's Tip: Keep your dressing dry and secure. If it gets wet, change it immediately to avoid infection.
Weeks 3 to 4
- By this stage, most patients become comfortable with tube management and daily activities.
- Follow-up imaging or blood tests may be scheduled to assess kidney function and decide if the tube is still needed.
- Some patients may transition to internal stents or have the tube removed if the blockage is resolved.
Doctor's Tip: Report any fever, chills, or pus-like drainage, these may be early signs of infection and need urgent attention.
Long-Term (If Tube Remains)
- If the nephrostomy tube is required for longer periods, it may need periodic changes (every 6-8 weeks) to prevent blockage.
- You can maintain a near-normal lifestyle with proper precautions, but activities like swimming or heavy exercise may be restricted.
Doctor's Tip: "Think of tube care as a routine, like brushing your teeth. Consistency keeps complications away."
Lifestyle Changes After Nephrostomy
- Keep the nephrostomy tube and site clean and dry to prevent infection.
- Avoid strenuous activity that could dislodge the tube.
- Monitor urine output and report any changes to your doctor.
- Attend all follow-up appointments for tube maintenance and removal.
- Maintain adequate hydration to support kidney function.
