If you’ve just had surgery for a kidney or ureteric stone — RIRS, ureteroscopy, or PCNL — there’s a good chance your surgeon left a thin, flexible tube inside your urinary tract before closing up. Patients usually hear it called a “DJ stent,” a “JJ stent,” or simply “the pipe the doctor put in.” Most go home relieved the stone is finally out, only to be caught off guard a day or two later by symptoms nobody quite explained in the discharge rush. That reaction is normal, and almost always manageable. Here is what the stent is actually doing, what to expect while it’s in, and what the removal visit itself really involves.
1. What Is a DJ Stent, and Why Did You Need One?
A DJ stent — DJ stands for “double-J,” describing the curled shape at each end — is a soft, hollow tube placed inside the ureter, the passage connecting your kidney to your bladder. One coiled end sits inside the kidney, the other curls inside the bladder, and those coils exist specifically so the stent doesn’t slip out of position while it’s doing its job.
After a procedure like RIRS, ureteroscopy, or PCNL, the ureter is often swollen from the instruments passed through it, and there may be small stone fragments still making their way out on their own. A stent holds the ureter open while that swelling settles, so urine can keep draining from the kidney into the bladder without getting blocked. Without it, a swollen or narrowed ureter could let urine back up into the kidney — a far more painful and potentially damaging problem than the stent itself.
Not every stone procedure needs a stent. The decision depends on how much the ureter was manipulated during surgery, whether there’s residual swelling or leftover fragments, whether infection was present, and sometimes whether you only have one functioning kidney. If your surgeon placed one, it was almost certainly because your ureter needed that extra support to heal safely rather than as a routine afterthought.
2. What You Might Feel With the Stent In Place
This is the part patients are rarely warned about clearly enough before they leave hospital. Having a stent in place is not usually painful in the way the original stone attack was, but it is genuinely uncomfortable for most people — and that discomfort is expected, not a sign that anything has gone wrong.
The most common sensations are a frequent, sometimes urgent need to urinate even soon after you’ve just gone, and a dull ache in the back or side that tends to worsen right after urinating or during physical activity. That particular pattern happens because urine can briefly reflux back up the stent toward the kidney with each void, which the kidney doesn’t appreciate. Many patients also notice mild to moderate blood in the urine, especially after exertion, simply because the stent rubs gently against the lining of the bladder and ureter as you move. A pulling or heavy sensation low in the abdomen is common too, and some patients find intimacy uncomfortable while the stent is in.
Research using validated stent-symptom questionnaires has found that a clear majority of patients experience at least some of these symptoms to a noticeable degree — common enough in urology that it has its own informal name, “stent syndrome.” Knowing that in advance tends to make it far less alarming when it actually happens.
3. How Long Does a DJ Stent Usually Stay In?
There’s no single number that fits every patient — it depends on what was found and done during your specific surgery. That said, most stents placed after routine stone procedures are removed within roughly one to three weeks. Clinical data on stent timing after ureteroscopy suggests that removing a stent very early, within the first four to five days, is actually associated with more unplanned visits around the time of removal rather than fewer — so “as short as possible” isn’t automatically the safest choice either. Current guidance leans toward keeping the stent in only as long as clinically necessary, which for an uncomplicated case usually lands somewhere between one and two weeks.
In more complex situations — significant swelling at surgery, infection, residual stone fragments, or a solitary functioning kidney — your urologist may deliberately leave the stent in for four to six weeks to be safe. The number that matters is not a general average you read online; it’s the specific date your own surgeon gives you, based on exactly what they found during your procedure.
4. Managing the Discomfort Day to Day
Most stent discomfort responds well to a few straightforward measures. Steady hydration through the day — regular sipping rather than large volumes all at once — tends to help more than it hurts, since very large amounts can briefly worsen the reflux sensation after voiding. Alpha-blocker tablets, commonly tamsulosin, are frequently prescribed specifically for stent discomfort, and several clinical trials have found they meaningfully reduce both urinary symptoms and pain scores compared with no treatment at all. Simple pain relief, and occasionally a bladder-relaxant medicine, round out the usual approach.
Heavy lifting and high-impact exercise are worth avoiding until the stent is out, since jarring movement tends to aggravate the ache. Some blood-tinged urine after activity is common and not, on its own, a reason for alarm. If discomfort is significant enough to disrupt sleep or daily function despite the medication prescribed, say so at your follow-up rather than simply enduring it — the dose or combination can usually be adjusted.
5. When to Call Your Urologist Without Waiting
Most stent symptoms are uncomfortable rather than dangerous. A smaller set of symptoms needs prompt evaluation instead of waiting it out:
- Fever or shaking chills
- Pain that is severe, constant, and not relieved by the medication you’ve been given
- Heavy, persistent bleeding rather than light blood-tinging
- Complete inability to pass urine
- The stent appearing to come out through the urethra before your scheduled removal date
Fever with a stent in place deserves particular attention. It can signal a urinary infection that has travelled up to the kidney, which needs timely treatment rather than a wait-and-see approach.
6. The Removal Procedure: What Actually Happens
This is usually the part patients dread most, and in practice it’s almost always quicker and less eventful than they’ve imagined. For most patients, stent removal is a short outpatient procedure done in the clinic rather than the operating theatre. A thin camera (cystoscope) is passed through the urethra under local anaesthetic gel, the lower coil of the stent is located and grasped, and the stent is gently withdrawn. The whole process typically takes just a few minutes, and patients usually describe a brief, odd pulling sensation rather than real pain.
Some patients have a stent placed with a fine extraction string left outside the body at the time of surgery. In that case, removal can be even simpler — the string is pulled gently in the clinic without needing a camera at all. Whether this option was used for you depends on your surgeon’s assessment during your original procedure, and it isn’t appropriate for every patient.
7. After the Stent Comes Out
Many patients notice the frequency, urgency, and ache easing within a day or two of removal, though mild burning or slight blood in the urine for a short period afterward is common and expected. Your urologist will usually want a follow-up visit, sometimes with a scan, to confirm the ureter has healed well and there’s no remaining obstruction.
8. Why the Removal Date Matters More Than Patients Realise
This is worth being direct about. A DJ stent is meant to be temporary, and leaving it in longer than intended is not a minor oversight. In practice, this is one of the most avoidable complications I see in urology, and also one of the easiest to prevent with a single phone reminder.
Research on “forgotten” stents — ones left in well beyond their intended removal date — shows that encrustation, mineral deposits building up on the stent surface, develops in the large majority of cases left too long, alongside a meaningfully increased risk of urinary infection and stent fragmentation. In severe, prolonged cases, this can progress to real damage to kidney function. This isn’t a rare, dramatic exception; it’s a well-documented pattern in the urology literature, and it’s entirely preventable.
The fix is simple. Know your removal date before you leave the hospital, write it down somewhere you’ll actually see it, and don’t assume that feeling fine means it can wait. Feeling fine with a stent in place is normal — it tells you nothing about how close you are to the point where complications start to build.
Frequently Asked Questions
Is it normal to see blood in my urine with a stent in? Yes, mild blood-tinging is common, especially after activity or exercise, because the stent gently rubs against the bladder and ureter lining. Heavy bleeding with clots, or bleeding that doesn’t settle with rest, should be reported promptly.
Can I feel the stent from the outside? No, the stent sits entirely inside the urinary tract and isn’t visible or felt externally, though some patients notice its effects internally, such as lower abdominal pressure.
Will the stent set off a metal detector at the airport? Modern DJ stents are made of flexible polymer, not metal, so they do not typically trigger metal detectors.
Can I work and travel with a stent in place? Most people can continue light daily activities and desk work. Strenuous exercise, heavy lifting, and long journeys without easy toilet access are best avoided until after removal — discuss specific travel plans with your urologist in advance.
Is stent removal more painful than the original stone surgery? No. Stent removal is a brief outpatient procedure, usually over within minutes, and is generally far less uncomfortable than either the stone episode or the surgery itself.
What happens if I miss my stent removal appointment? Contact your urologist’s clinic to reschedule as soon as possible rather than letting it lapse. The complications associated with a stent left in too long increase the longer removal is delayed, so this isn’t an appointment worth postponing indefinitely.
Can the stent move or fall out on its own before removal? It’s uncommon but possible, particularly with significant coughing or straining, or if the stent wasn’t optimally positioned. If you notice the stent protruding or suspect it has shifted, contact your urologist rather than trying to reposition or remove it yourself.
Will I need another stent if I get a kidney stone again in future? Not necessarily. It depends on the procedure used for the next stone and how your ureter responds at the time. Many patients go through stone treatment without ever needing a stent, depending on the specifics of the case.
Closing
A DJ stent is a short, deliberately temporary part of your stone treatment, not a long-term fixture, and the discomfort it causes — while real — is both well understood and manageable with the right support. The single most useful thing you can do is keep your removal date firmly in mind and raise any fever, severe pain, or heavy bleeding promptly rather than waiting it out. Most patients look back on the stent period as the most forgettable part of their stone treatment once it’s finally out.
