A ureteral stent after kidney stone removal is a small temporary tube that keeps urine flowing from the kidney to the bladder while the ureter heals. It is common after ureteroscopy, laser stone treatment, and some larger stone procedures. The stent is not the stone treatment itself. It is a short-term support device used after the stone has been removed, broken up, or bypassed.
The frustrating part is that a stent often causes symptoms of its own. You might feel burning when you pee, bladder pressure, urgency, blood in the urine, or sharp flank pain at the end of urination. These symptoms feel alarming when no one has explained them clearly. Most are expected, but some signs need prompt medical attention.
This guide explains why the stent is used, what side effects are normal, what is not normal, how long the stent usually stays in, how removal works, and what helps you get through the days before it comes out.

Why a Stent Is Used After Stone Removal
A ureteral stent keeps the ureter open after a kidney stone procedure. The ureter is the narrow tube that drains urine from the kidney into the bladder. After stone removal, that tube often becomes irritated or swollen. A small amount of swelling in the wrong place blocks urine flow, raises kidney pressure, and causes severe pain.
The stent prevents that problem while the tissue settles down. One curled end sits in the kidney and the other curled end sits in the bladder. These curls stop the tube from sliding out of position. Most stents are soft plastic and very thin, but the bladder and ureter still notice they are there.
Doctors use stents for several practical reasons:
- The ureter looked swollen after the stone came out.
- The stone was stuck, large, sharp, or embedded in the ureter wall.
- Laser treatment created dust or small fragments that still need to pass.
- The surgeon used instruments that stretched or irritated the ureter.
- There was bleeding, infection risk, narrowing, or concern about blockage.
- A second procedure is planned.
- The patient has one kidney, reduced kidney function, pregnancy, or another situation where blocked drainage would be higher risk.
Not every stone procedure needs a stent. After a very simple ureteroscopy with no swelling, no injury, no infection, and no leftover fragments, some surgeons skip it. In real life, many people still leave the operating room with one because the surgeon saw a reason during the procedure. The decision often comes from what happened inside the ureter, not only from the stone size seen on the scan.
The stent is especially common after ureteroscopy, where a small scope is passed through the urinary tract to reach the stone. If you are comparing procedures or trying to understand why your recovery differs from someone else’s, the details in kidney stone surgery options help explain how ureteroscopy, shock wave lithotripsy, and PCNL differ.
A stent does not dissolve the stone. It also does not prevent every twinge of pain. Its job is drainage. Think of it as a temporary internal splint for a tube that has just been scraped, stretched, or inflamed.
What a Kidney Stone Stent Feels Like
The most common stent feeling is the sudden need to pee even when the bladder is nearly empty. The lower curl of the stent rests inside the bladder, and the bladder reads that contact as irritation. This creates urgency, frequency, pressure, and sometimes cramping.
Many people describe the feeling as a bladder infection without an infection: burning, pressure, and repeated trips to the bathroom. Others feel more discomfort in the kidney area, especially during or right after urination. That happens because bladder squeezing sends pressure up the stent toward the kidney. The result is a sharp ache or spasm in the flank.
Common stent symptoms include:
- Urinating more often than usual
- Urgency that feels hard to hold
- Burning or stinging when urine passes
- Pink, red, tea-colored, or rusty urine
- Small clots or stringy blood, especially after activity
- Bladder pressure or pelvic aching
- Flank pain on the stent side
- Pain at the end of urination
- Feeling like you cannot fully empty the bladder
- Discomfort with walking, bending, or riding in a car
- Testicle, groin, labial, or lower belly pain from referred nerve pain
These symptoms often rise and fall during the day. Morning urine is usually more concentrated, so burning and color look worse early. More walking, stairs, errands, or lifting often leads to more blood in the urine later in the day. That pattern is common with a stent.
A stent also changes how stone recovery feels. Kidney stone pain before surgery often comes in waves as the stone blocks urine flow. Stent discomfort is usually more tied to urination, bladder filling, movement, and irritation. If your pain feels different from the original stone attack, that does not automatically mean the stone is still there.
The symptoms still deserve attention when they are intense. Severe pain, fever, inability to urinate, or heavy bleeding with clots is not something to “push through.” The section below separates expected stent effects from signs that need a call to your urology team.
Normal Side Effects vs Warning Signs
Some blood, burning, urgency, and flank discomfort are expected after a ureteral stent. The key is pattern and severity. Mild-to-moderate symptoms that improve with rest, fluids, and prescribed medicine fit typical recovery. Symptoms that keep escalating, come with fever, or stop urine flow need urgent medical guidance.
| Symptom | Often expected with a stent | Call your doctor urgently or seek care if |
|---|---|---|
| Blood in urine | Pink, red, rust, or tea-colored urine that changes during the day | Heavy bleeding, large clots, or urine that stays thick and dark despite rest and fluids |
| Burning when peeing | Mild or moderate burning, especially the first few days | Burning comes with fever, chills, worsening pelvic pain, or foul-smelling urine |
| Urgency and frequency | Needing to pee often, sometimes every 30–60 minutes | You cannot urinate, only dribble, or develop painful bladder swelling |
| Flank pain | Ache or spasm on the stent side, often during or after urination | Pain is severe, new, worsening, or not controlled by the plan you were given |
| Temperature | No fever, or slight warmth right after anesthesia that resolves | Fever of 100.4°F or 38°C or higher, shaking chills, or feeling seriously ill |
| Nausea | Mild nausea from anesthesia or pain medicine | Repeated vomiting prevents fluids or medications from staying down |
Blood in the urine
Blood in the urine is one of the most common stent side effects. The stent rubs lightly as you move, and the treated area is still healing. Urine color often looks worse after walking, housework, stairs, sex, constipation straining, or a long car ride.
Light bleeding usually improves with rest and steady fluids. It does not need to be perfectly clear every time you pee. A better question is whether the urine keeps flowing, whether clots are small, and whether the color lightens when you slow down.
A separate concern is blood that appears without a recent procedure or continues beyond the recovery period. Persistent or unexplained bleeding needs evaluation because blood in urine has causes beyond stones and stents.
Fever and chills
Fever after stone surgery matters because an infected, obstructed urinary system becomes serious quickly. A stent helps drainage, but it does not make infection impossible. Call your urology team or seek urgent care for fever of 100.4°F or 38°C or higher, shaking chills, confusion, weakness, or a fast worsening “flu-like” feeling.
Do not wait to see whether a fever disappears overnight after a urinary procedure. Infection after stone treatment needs prompt assessment, urine testing, and sometimes imaging or IV antibiotics.
Trouble urinating
Urgency is common. Complete inability to urinate is different. If you feel a painfully full bladder and cannot pass urine, seek urgent care. This is especially important after anesthesia, after taking opioid pain medicine, or if you have prostate enlargement or a history of urinary retention.
Painful dribbling, lower belly swelling, and repeated failed attempts to pee are red flags. A stent sits between the kidney and bladder; it does not guarantee the bladder itself empties well. The signs of urinary retention need same-day attention.
How Long the Stent Stays In
Most stents after kidney stone removal stay in for a few days to two weeks. Some come out sooner, especially after an uncomplicated ureteroscopy. Others stay longer when the ureter needs more healing time, infection was present, swelling was significant, or another procedure is planned.
A common schedule after ureteroscopy is 3–7 days. Another common plan is 1–2 weeks. After larger or more complex procedures, the stent might stay longer. The exact plan comes from the surgeon’s findings, not from a universal rule.
Several details change the timeline:
- Simple stone removal: Shorter stent time is more likely when the ureter looks healthy and drainage is good.
- Impacted stone: A stone that was stuck in the ureter often leaves swelling and irritation, so the stent stays longer.
- Ureter injury or narrowing: Any concern about healing or scarring usually leads to a longer stent period.
- Infection or pus behind the stone: Drainage and antibiotics come first, and definitive treatment or removal timing is more cautious.
- Residual fragments: Small pieces still passing through the ureter keep irritation higher.
- Pregnancy or high-risk kidney situations: Doctors avoid blockage more aggressively.
Do not remove a stent early unless your urology team gave clear instructions. Early removal increases the chance of ureter swelling, blocked drainage, kidney pain, an emergency visit, or another procedure.
Also, do not let a stent stay in beyond the planned date without contacting the office. Stents are temporary. Over time, minerals in urine coat the stent, a process called encrustation. The longer it stays, the harder removal becomes. Forgotten stents create avoidable problems, including infection, blockage, stone formation on the stent, and difficult removal.
Before leaving the surgery center, you should know three things: whether you have a stent, whether it has a string, and the exact removal plan. If you were groggy after anesthesia and do not remember, call the office and ask. This is not a minor detail.
How to Manage Stent Pain, Urgency, and Bleeding
The best stent symptom plan usually combines steady hydration, timed activity, pain medicine, bladder-calming medicine when prescribed, and avoiding common irritants. No single trick removes all discomfort, but the right routine often makes the days before removal much easier.
Use the medication plan as written
Your discharge instructions matter more than generic advice because they reflect your surgery, kidney function, bleeding risk, allergies, and other conditions. Common medication plans include:
- Acetaminophen for baseline pain control.
- An NSAID, such as ibuprofen or ketorolac, when safe for that patient.
- An alpha blocker, such as tamsulosin, to reduce ureter spasm and stent discomfort.
- A bladder spasm medicine, such as oxybutynin, solifenacin, or a similar medication.
- Phenazopyridine for short-term urinary burning, if your clinician says it is appropriate.
- A small amount of opioid pain medicine for breakthrough pain in selected cases.
NSAIDs are often useful for stone and stent pain, but they are not safe for everyone. People with chronic kidney disease, stomach ulcers, blood thinners, certain heart conditions, high bleeding risk, or specific surgery instructions need personalized guidance. Do not add ibuprofen or naproxen on top of a plan that told you to avoid them.
Phenazopyridine turns urine bright orange and stains underwear, towels, and toilet seats. It treats burning sensation, not infection. It should not be used as a way to ignore fever, chills, or worsening pain.
Drink steadily, not aggressively
Clearer urine usually burns less, and steady urine flow helps small stone dust pass. The goal is regular fluid intake across the day, not forcing huge amounts at once.
A practical approach is to sip water regularly and aim for pale yellow urine. If your doctor gave a fluid restriction because of heart, kidney, or liver disease, follow that limit. Drinking extreme amounts does not flush the stent pain away. It often makes urgency and bladder pressure worse.
People who form stones often need a long-term hydration plan after recovery, but the first few days with a stent are about balance. Once the stent is out, prevention-focused hydration becomes more important. A guide to kidney-friendly hydration gives more detail on daily fluid targets and when extra water is not the right answer.
Calm the bladder
The bladder becomes more irritable when urine is concentrated or when drinks stimulate it. During the stent period, consider cutting back on:
- Coffee and energy drinks
- Strong tea
- Alcohol
- Carbonated drinks
- Citrus juice
- Spicy foods
- Artificial sweeteners if they trigger urgency for you
Not everyone reacts to these, but a short break is often worth it when urgency is controlling your day. Choose water, diluted non-citrus drinks, or other mild fluids instead.
Heat also helps some people. A heating pad over the lower belly or flank eases muscle spasm. Use a warm setting, keep a cloth layer between the heat source and skin, and avoid sleeping on an active heating pad.
Prevent constipation
Constipation makes stent symptoms worse because straining increases pelvic pressure and irritates the bladder. Opioid pain medicine, anesthesia, low activity, and dehydration all slow bowel movements.
Use the stool softener or laxative recommended in your discharge papers. Gentle walking, fluids, and fiber from food also help. Call your care team if you have significant belly swelling, vomiting, or no bowel movement despite following the plan.
Daily Activity With a Stent
Most people walk the same day or the day after kidney stone removal, but a stent rewards pacing. Too much activity often leads to more bleeding, urgency, and flank pain. Too little movement increases constipation, stiffness, and sluggish recovery.
A useful rule is to increase activity in small steps. Walk around the house first, then take short outdoor walks, then return to errands and normal routines as symptoms allow. If your urine turns darker red or pain spikes after activity, rest and hydrate. That feedback usually means you did more than your bladder and ureter liked that day.
Avoid heavy lifting, intense workouts, running, cycling, and abdominal straining until your surgeon clears you. These activities bounce or tug the stent and increase bleeding. Even if you feel good for an hour, symptoms often flare later.
Driving depends on three things: anesthesia recovery, pain control, and medication. Do not drive while taking opioid pain medicine or any medication that makes you sleepy or dizzy. Also avoid driving if urgency is so intense that you cannot safely focus.
Work depends on the job. Desk work from home is often manageable within a few days. Jobs involving lifting, climbing, driving routes, warehouse work, patient transfers, construction, or long hours without bathroom access usually need more time or modified duties.
Sex is another area where instructions differ. If your stent has a string visible outside the body, ask your urology team before sex because the string can be pulled accidentally. Even without a string, sex can increase bleeding, pelvic pressure, and discomfort while the stent is in. Wait until you feel comfortable and follow any restrictions in your discharge paperwork.
Showering is usually allowed, including with a stent string, unless your instructions say otherwise. Avoid pulling, scrubbing, trimming, or tucking the string tightly. Do not take baths, swim, or use hot tubs until your care team says it is safe, especially soon after surgery or with a visible string.
What Happens When the Stent Is Removed
Stent removal is usually quick. The method depends on whether the stent has a string.
With a string, the stent is removed by gently pulling the string at the instructed time. Some offices do this in clinic. Some surgeons tell patients to remove it at home on a specific day. Follow the instructions exactly. Do not pull it early, and do not remove it if you are unsure whether the date is correct.
Without a string, removal is usually done with cystoscopy in the office. A cystoscope is a thin tube with a camera that passes through the urethra into the bladder. The clinician grasps the stent and slides it out. The process is brief, but it feels strange and uncomfortable. Many people describe pressure, burning, or a strong urge to pee rather than sharp pain.
You might have burning, frequency, and blood in the urine for 24–48 hours after removal. Some people also get flank cramping for several hours as the ureter adjusts. Drinking steadily and using approved pain medicine helps.
Call your doctor after removal if you develop fever, chills, inability to urinate, severe worsening flank pain, or heavy bleeding. Mild burning is common. A fever is not.
Many readers worry that removal will be worse than living with the stent. In most cases, the opposite is true. The removal itself is short, and bladder irritation often improves quickly afterward. If your symptoms were mainly urgency, pressure, and pain at the end of urination, relief often starts the same day or within a few days.
Follow-Up and Preventing Another Stone
The stent coming out is not always the end of kidney stone care. Your doctor still needs to confirm healing, check whether fragments remain, review stone analysis if available, and decide whether prevention testing is needed.
Follow-up often includes one or more of these steps:
- A clinic visit after stent removal
- Urine testing if infection symptoms were present
- Imaging, such as ultrasound, X-ray, or CT, to check for swelling or fragments
- Stone analysis if a piece was collected
- Blood tests for calcium, kidney function, uric acid, or other factors
- A 24-hour urine collection for people at higher risk of recurrence
Not everyone needs the same workup. A first small stone in a low-risk person might lead to basic prevention advice. Recurrent stones, multiple stones, young age, a strong family history, one kidney, bowel disease, gout, unusual stone type, or kidney disease usually deserves a deeper evaluation. A 24-hour urine test for kidney stones shows whether urine volume, calcium, oxalate, citrate, sodium, uric acid, or pH is driving risk.
Stone prevention should be specific to the stone type. Calcium oxalate stones, uric acid stones, struvite stones, and cystine stones do not all have the same prevention plan. General advice like “drink more water” helps many people, but it is not enough for everyone. If you do not know your stone type, ask whether stone analysis was done.
Common prevention steps include:
- Keeping urine diluted through the full day, not only drinking a lot at night
- Reducing high-sodium foods because salt raises urine calcium
- Eating normal dietary calcium with meals unless your clinician says otherwise
- Avoiding very high-dose vitamin C supplements if you form calcium oxalate stones
- Limiting large portions of animal protein if uric acid or calcium stone risk is high
- Treating recurrent UTIs promptly, especially with infection stones
- Using prescribed prevention medicine when diet alone is not enough
The right plan depends on the lab pattern. For example, low urine citrate is different from high urine calcium. High urine oxalate is different from acidic urine. A practical overview of kidney stone prevention explains how hydration, diet, and medications fit together after recovery.
Also keep a copy of your procedure details. Ask what stone was treated, where it was located, whether fragments remain, whether the ureter was injured or narrowed, when imaging is planned, and when to seek care. These details help if you have pain later or end up in urgent care while traveling.
