What to Expect After Passing a Kidney Stone

Once a kidney stone passes, most pain fades quickly, but your body needs a few days to fully recover. You can expect some residual soreness, blood-tinged urine, and increased urinary frequency as the irritated tissues heal. These symptoms are normal and typically resolve within a few days, though the exact timeline depends on the size of the stone and whether you had any procedures like stent placement.

Residual Pain and Soreness

The sharp, intense pain of a kidney stone episode usually stops once the stone exits your body. What lingers is a duller, more general soreness caused by inflammation along the path the stone traveled. The tube connecting your kidney to your bladder (the ureter) and the urethra can both be irritated or mildly inflamed from the stone scraping through, and this discomfort typically clears up within a few days.

Larger stones tend to cause more irritation on the way out. You might also notice that pain briefly returns as the stone leaves the bladder through the urethra, even if you felt relief once it dropped into the bladder. This final stretch of discomfort is usually short-lived. Over-the-counter pain relievers and a heating pad on your lower back or abdomen can help during this window.

Blood in Your Urine

Seeing pink, red, or brown-tinged urine after passing a stone is common and not immediately alarming. The stone scratches the lining of your urinary tract as it moves through, and those small abrasions bleed slightly. In most cases, this clears up within a few days as the tissue heals. Cloudy or foul-smelling urine, on the other hand, can signal an infection and warrants prompt attention.

Urinary Changes to Expect

You may feel the urge to urinate more frequently than usual, or notice a burning sensation when you go. This is your urinary tract’s response to the inflammation left behind. Drinking plenty of water helps flush the system and dilute your urine, which makes these sensations less intense. Most people find that the burning and urgency settle within the first couple of days.

If You Had a Stent Placed

Some people have a ureteral stent placed during treatment to keep the ureter open while the stone passes or after a procedure to remove it. Stent removal itself is quick, usually taking under five minutes. About a third of patients experience cramping or spasms in the kidney, back, or urethra on the day of removal, though for more than half of those people the pain lasts less than four hours.

Burning with urination after stent removal is common but brief. Most people who experience it say it only lasts for the first one to three bathroom trips. Urinary urgency and frequency can spike immediately after removal but generally resolve within 24 hours. A few people report a “phantom” sensation, as if the stent is still there, which fades on its own.

While the majority of people feel completely back to normal within a day of stent removal, about a third report lingering symptoms for two to three days, and a smaller number experience discomfort for up to two weeks. These lingering symptoms are usually a dull ache, occasional blood in the urine, or continued urgency rather than the sharp pain of the original stone episode.

Signs That Something Is Wrong

Fever is the most important warning sign after passing a kidney stone. A fever with chills can indicate an infection in the urinary tract, which combined with a recent stone episode is a serious situation that requires immediate medical evaluation. Don’t wait this one out.

It’s also worth knowing that feeling better doesn’t always mean the stone has fully passed. Pain can completely resolve even when a stone is still partially blocking the kidney. If you didn’t see or catch the stone in your urine, a follow-up with a urologist is a good idea to confirm it’s actually gone. Persistent nausea, vomiting, or pain that returns after initially improving are also reasons to check in.

How to Reduce Your Risk of Another Stone

Kidney stones have a frustratingly high recurrence rate. If you’ve had one, your odds of forming another are significant, which makes prevention worth taking seriously. The single most impactful thing you can do is drink enough fluid to produce at least 2.5 liters of urine per day. That’s the target recommended by both the American Urological Association and the Canadian Urological Association. For most people, this means drinking roughly 3 liters of fluid daily, since some water is lost through sweat and breathing.

Beyond hydration, dietary changes depend on what type of stone you had. If your doctor identified the stone (through analysis of a captured stone or imaging), the specific composition guides what to adjust.

Calcium Oxalate Stones

These are the most common type. Counterintuitively, you should not cut calcium from your diet. Calcium in food actually binds to oxalate in your digestive tract and prevents it from reaching your kidneys. The goal is to reduce high-oxalate foods instead: spinach, rhubarb, nuts and nut products, peanuts, and wheat bran are the biggest contributors. Keeping sodium below 2,300 mg per day also helps, because high sodium intake increases the amount of calcium your kidneys filter, raising stone risk. That means watching canned foods, packaged meals, fast food, and processed meats.

Uric Acid Stones

These are more closely tied to diet and body weight. Reducing animal protein is the main lever. Beef, pork, chicken (especially organ meats), eggs, fish, and shellfish all increase uric acid production. Replacing some animal protein with plant-based sources like beans, lentils, and soy foods can help. Losing weight, if you carry extra, is particularly important for uric acid stone formers.

General Dietary Principles

Regardless of stone type, limiting sodium and moderating animal protein are beneficial. Getting calcium from food rather than supplements, choosing plant-based protein sources more often, and staying consistently hydrated form the foundation of stone prevention. These aren’t temporary fixes. The changes need to be sustained to meaningfully lower your recurrence risk.

Stone Analysis and Follow-Up

If you managed to catch your stone (using a strainer when you urinate is the standard approach), bring it to your doctor for analysis. Knowing the composition tells you and your care team exactly which dietary and medical strategies are most likely to prevent the next one. Even if you didn’t catch it, a follow-up visit is valuable. Your doctor can check imaging to confirm the stone is fully passed, evaluate for any remaining fragments, and run a metabolic workup through blood and urine tests to identify underlying risk factors like high calcium, high oxalate, or low citrate levels. These results shape a personalized prevention plan that goes beyond general advice.
