Passing a kidney stone is often described as the closest a man can get to childbirth. If you’re reading this, you probably don’t need the poetry—you need a plan. So here’s a practical, step-by-step breakdown of kidney stones treatment, from the first twinge to the final stone in a strainer. No fluff, just the steps that matter.
Step 1: Confirm It’s a Kidney Stone Before You Start Treatment
The pain of a kidney stone usually hits in waves—sharp, cramping pain in your side or lower back that radiates toward your groin. You might also see blood in your urine or feel nauseous. But those symptoms can overlap with appendicitis, a urinary tract infection, or even a muscle strain. Don’t guess. A 34-year-old runner might dismiss it as a pulled oblique, only to end up in urgent care with a 4mm stone stuck at the ureterovesical junction.
If you have a fever, chills, or can’t urinate at all, skip the doctor’s office and go straight to the emergency room. Otherwise, your first step is a clinic visit. The standard tests are a non-contrast CT scan (the gold standard), an ultrasound, and a urine test to check for infection. A CT scan will tell you the exact size and location of the stone—critical information that shapes every treatment decision from here.
Step 2: Immediate Relief While You Decide on Treatment
Once you know you’re dealing with a kidney stone, the next few hours are about managing pain and giving the stone a chance to move on its own. Here’s what to do right away:
- Hydrate aggressively. Aim for 2–3 liters of water per day. If vomiting prevents you from keeping fluids down, call your doctor—you may need IV fluids.
- Use NSAIDs. Ibuprofen or prescription ketorolac (Toradol) work better for renal colic than opioids in many studies. They reduce inflammation around the stone, which eases the ureter’s spasms.
- Apply a heating pad to your side or back. It won’t pass the stone, but it relaxes muscles and can take the edge off.
- Strain every urine sample. Use a fine mesh strainer (the clinic usually gives you one) so you can catch the stone. A caught stone can be analyzed to guide prevention.

Step 3: Medical Treatment Options—What Your Doctor Will Consider
Not every stone requires a procedure. In fact, about 80% of stones smaller than 5mm pass on their own within a few weeks. The key is to identify which stones are worth the wait and which are just going to torture you while you wait.
Watchful Waiting
If your stone is under 5mm and your pain is manageable with oral NSAIDs, your doctor may suggest giving it 1–2 weeks to pass. You’ll go home with a strainer, a prescription for pain relief, and a number to call if things get worse. This isn’t a passive plan—you’re actively hydrating, moving (gentle walking helps), and tracking your symptoms.
Medications to Speed Things Up
For stones in the 5–10mm range, a class of drugs called alpha-blockers can relax the ureter and help the stone slip out faster. Tamsulosin (Flomax) is the most common. A 6mm stone in the lower ureter has a much higher chance of passing with tamsulosin than without—some studies show the success rate jumps from 25% to over 60% within two weeks. It’s not a guarantee, but it’s a low-risk option many doctors try before jumping to surgery.
Step 4: Interventional Treatments—When Waiting Isn’t Working
If the stone is too large (typically over 10mm), causing uncontrollable pain, blocking urine flow, or riding along with an infection, you’ll need one of three procedures. The choice depends on stone size, location, and your anatomy.
Shock Wave Lithotripsy (SWL)
This outpatient procedure uses focused sound waves to break the stone into sand-like pieces that you pass in the following days or weeks. It works best for stones under 10mm in the kidney or upper ureter. The downside: it can leave small fragments behind, especially if the stone is in the lower pole of the kidney, where gravity works against clearance.
Ureteroscopy with Laser
A thin scope goes up through the urethra and bladder into the ureter. A laser zaps the stone into dust, and tiny baskets retrieve any larger fragments. This approach has a higher one-time success rate than SWL for most stones, including those in the lower ureter. You’ll likely have a temporary stent placed for a few days to help swelling subside.
Percutaneous Nephrolithotomy (PCNL)
For very large stones—over 20mm, or staghorn stones that fill the kidney’s branching structures—PCNL is the go-to. It numbs or sedates you, makes a half-inch incision in your flank, and removes the stone directly. It’s more invasive, but it clears the kidney far better than SWL or ureteroscopy for big stones.
Your urologist will walk you through the risks and success rates based on your specific case. Ask about the surgeon’s experience—stone treatment is skill-sensitive.
Step 5: Prevent Recurrence—The Treatment That Lasts
Passing a stone is a one-time event for many people, but up to 50% of patients have another stone within five years. The most effective kidney stones treatment is the one you do after the current stone is gone. Here’s your prevention playbook:
- Drink enough water to produce at least 2.5 liters of urine per day. A simple way to check is to keep your urine pale yellow.
- Cut back on sodium—high sodium increases calcium in your urine. Processed foods are the biggest culprit.
- Don’t eliminate calcium. Too little dietary calcium can actually increase oxalate absorption and stone risk. Get it from food, not pills.
- Limit oxalate-rich foods like spinach, rhubarb, almonds, and beets—but don’t ban them. Pair them with a calcium source to bind oxalate in the gut.
- Maintain a healthy weight. Obesity treatment and weight loss programs can directly lower your recurrence risk because insulin resistance and poor diet both promote stone formation.

Step 6: Know When a Kidney Stone Becomes a Kidney Infection
A stone can block urine flow, and stagnant urine is a breeding ground for bacteria. If you develop a fever, chills, or flank pain that worsens alongside cloudy or foul-smelling urine, that’s a red flag for pyelonephritis or a urinary tract infection. In that case, you need antibiotics and sometimes emergency drainage of the kidney—not just pain relief. Delaying treatment can lead to sepsis.
If you’re prone to UTIs, you should also be aware of how UTI treatment and prevention overlaps with stone care, especially since stones can harbor bacteria. And if you’re experiencing the more severe kidney infection symptoms, this pyelonephritis causes, symptoms, treatment, and prevention guide explains what to watch for.
Your Step-by-Step Action Plan
Here’s the practical takeaway you can act on today:
- Get imaging to confirm stone size and location.
- Start hydration and NSAIDs for immediate relief.
- Discuss watchful waiting or tamsulosin for stones under 10mm.
- Choose a procedure (SWL, ureteroscopy, or PCNL) for larger or stubborn stones.
- Strain your urine and save the stone for analysis.
- Schedule a 24-hour urine test after recovery to identify metabolic risks.
- Adjust your diet and lifestyle to prevent the next one.
Every stone is different, and this plan is a framework, not a substitute for professional advice. But with the right steps in the right order, you’ll shorten the suffering and cut your odds of a repeat performance.
