Stent After Stone Surgery: Why It’s Needed & Is It Painful?: Kidney stone surgery has undergone a remarkable transformation over the past few decades. Procedures that once required large incisions and prolonged hospital stays are now performed using minimally invasive techniques such as Retrograde Intrarenal Surgery, ureteroscopy, and mini-percutaneous nephrolithotomy.
Yet, despite these advancements, one small device continues to raise big questions among patients:
👉 “Why do I need a stent after surgery?”
👉 “Is it painful?”
👉 “Can I avoid it?”
This article addresses these concerns in detail, explaining the science, necessity, benefits, risks, and patient experience of ureteral stents after stone surgery.
What is a Ureteral Stent?
A ureteral stent is a thin, flexible tube placed inside the ureter (the tube connecting the kidney to the bladder).
Key Features
- Made of soft biocompatible material
- Typically has a “double J” shape (curled at both ends)
- One end sits in the kidney, the other in the bladder
👉 Hence, it is commonly called a Double J (DJ) stent.
Why is a Stent Placed After Stone Surgery?
The primary purpose of a stent is to ensure smooth urine drainage and prevent complications.
1. Prevents Obstruction
After surgery:
- Swelling of the ureter is common
- Stone fragments may block urine flow
The stent keeps the passage open.
2. Reduces Risk of Painful Blockage
Without a stent:
- Even small swelling can obstruct urine
- This can cause severe pain or kidney pressure
👉 The stent acts as a safety channel.
3. Promotes Healing
Surgical manipulation causes:
- Minor trauma
- Inflammation
The stent allows the ureter to heal properly without collapsing.
4. Facilitates Passage of Residual Fragments
After procedures like Retrograde Intrarenal Surgery, small stone fragments may remain.
The stent helps:
- Smooth passage of fragments
- Reduces risk of blockage
5. Prevents Serious Complications
Without a stent, patients may develop:
- Hydronephrosis (kidney swelling)
- Infection
- Acute kidney injury
👉 Studies show that stenting significantly reduces postoperative complications (PubMed, endourology studies).
Is Stent Always Required?
Not always—but often.
Stent is Recommended When:
✔ Large stone treated
✔ Prolonged surgery
✔ Ureteral trauma or edema
✔ Residual fragments present
✔ Infection risk
Stent May Be Avoided When:
✔ Small stones
✔ Short, uncomplicated procedures
✔ No ureteral injury
👉 Decision depends on clinical judgment and patient safety.
Is the Stent Painful?
This is the most common concern.
👉 Short answer: It can cause discomfort, but not always severe pain.
Understanding Stent-Related Symptoms
Common Symptoms
- Mild flank pain
- Burning during urination
- Frequent urge to urinate
- Feeling of incomplete emptying
These occur because:
- The stent irritates the bladder
- Urine may reflux toward the kidney
How Common is Discomfort?
Studies suggest:
- Around 50–70% of patients experience mild symptoms
- Severe symptoms are less common
(References: Urology journals, stent-related symptom studies)
Why Does Pain Occur?
- Bladder irritation
- Reflux of urine into kidney during urination
- Mechanical friction of the stent
How Severe is the Pain?
Pain varies from person to person.
Typical Experience
- Mild discomfort in most patients
- Manageable with medications
Rare Cases
- Moderate to severe discomfort
- Requires additional treatment
👉 Importantly, pain is temporary and reversible after stent removal.
How Long is the Stent Kept?
Duration depends on the procedure:
- Simple cases: 5–7 days
- Moderate cases: 2–4 weeks
- Complex cases: longer duration
👉 The goal is to remove it as early as safely possible.
Stent Removal: Is It Painful?
Another common fear.
👉 Stent removal is quick and usually minimally uncomfortable.
Procedure
- Done under local anesthesia or short OPD procedure
- Takes a few minutes
Patients often describe it as:
👉 “Uncomfortable but tolerable”
Can You Live Normally With a Stent?
Yes, but with some precautions.
Daily Activities
✔ Walking
✔ Office work
✔ Light activities
Avoid
- Heavy lifting
- Strenuous exercise
- Dehydration
Tips to Reduce Stent Discomfort
1. Stay Well Hydrated
- Flushes the urinary system
- Reduces irritation
2. Medications
Doctors may prescribe:
- Alpha-blockers
- Pain relievers
- Anticholinergics
Studies show these medications significantly reduce stent symptoms (PubMed studies on stent symptom management).
3. Avoid Holding Urine
Frequent voiding reduces discomfort.
4. Limit Caffeine
Reduces bladder irritation.
Complications of Not Using a Stent
Avoiding a stent when needed can lead to:
- Severe pain
- Urinary obstruction
- Infection
- Emergency hospitalization
👉 In many cases, a stent prevents bigger problems.
Advances in Stent Technology
Modern stents are designed to improve comfort:
- Softer materials
- Better flexibility
- Drug-eluting stents (under research)
These innovations aim to:
👉 Reduce symptoms and improve patient experience
Myths vs Facts
❌ “Stent means surgery went wrong”
👉 False. It is a planned protective measure.
❌ “Stent pain is unbearable”
👉 False. Usually mild and manageable.
❌ “It can stay forever”
👉 False. Must be removed as advised.
Special Situations
1. Patients with Infection
Stent helps drain infected urine.
2. Bilateral Procedures
Stenting becomes even more important.
3. Solitary Kidney
Stent ensures uninterrupted kidney function.
Clinical Evidence: What Studies Show
Medical research confirms:
- Stents reduce postoperative complications
- Improve drainage and healing
- Increase safety of procedures like RIRS and ureteroscopy
However:
- They are associated with temporary symptoms
👉 Overall, benefits outweigh discomfort.
Patient Perspective: What to Expect
Day 1–2
- Mild discomfort
- Burning sensation
Day 3–7
- Symptoms stabilize
- Patient adapts
After Removal
- Immediate relief
- Symptoms disappear
When to Contact Your Doctor
🚨 Seek medical help if:
- Severe pain
- Fever
- Blood in urine (excessive)
- Difficulty passing urine
Conclusion
A ureteral stent after stone surgery is not just an accessory—it is a critical component of safe and effective treatment.
While it may cause temporary discomfort, it plays a vital role in:
- Preventing complications
- Ensuring proper healing
- Improving surgical outcomes
👉 The key message is simple:
“A short period of discomfort can prevent serious long-term complications.”
Understanding its purpose helps patients feel more confident and less anxious about their recovery.
