Introduction
A 14mm kidney stone is considered a relatively large urinary stone and is less likely to pass naturally compared with smaller stones. Patients diagnosed with a stone of this size often want to know whether medicines or home remedies can remove it, or whether a procedure is necessary.
The appropriate kidney stone 14mm treatment depends on several factors, including the stone's location, composition, anatomy of the urinary tract, symptoms, degree of obstruction, infection status, and overall kidney function.
A 14mm stone should not be assumed to require one specific procedure in every patient. Depending on its location and characteristics, treatment may include shock wave lithotripsy (SWL/ESWL), ureteroscopy with laser lithotripsy, RIRS, or percutaneous nephrolithotomy (PCNL). A urologist generally performs stone-removal procedures, while a nephrologist can evaluate kidney function, metabolic risk factors, recurrent stone disease, and associated kidney conditions.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist, provides comprehensive kidney and stone-related evaluation, kidney function assessment, metabolic evaluation, prevention guidance, and coordination with appropriate urology specialists when a stone procedure is required.
Is a 14mm Kidney Stone Large?
Yes. A stone measuring 14mm (1.4cm) is considered relatively large compared with stones that are more likely to pass spontaneously.
The possibility of natural passage depends on:
-
Stone size
-
Stone location
-
Stone shape
-
Ureter anatomy
-
Degree of obstruction
-
Previous stone passage
-
Symptoms
-
Infection
-
Kidney function
A stone located in the kidney may cause few symptoms, while a 14mm stone lodged in the ureter can cause significant obstruction and pain.
Can a 14mm Kidney Stone Pass Naturally?
A 14mm stone is unlikely to pass naturally in many situations, particularly if it has entered the ureter.
Small stones have a greater chance of spontaneous passage. As stone size increases, the likelihood of passage decreases.
Medication may sometimes help selected patients with certain ureteral stones, but medicines cannot reliably make a 14mm stone disappear.
If the stone is causing persistent obstruction, severe symptoms, recurrent infections, or kidney-function concerns, active treatment may be recommended.
What Happens If a 14mm Stone Is Left Untreated?
Not every asymptomatic kidney stone requires immediate intervention, but a large stone should be assessed by a specialist.
Potential complications of an obstructing stone include:
-
Recurrent severe pain
-
Hydronephrosis
-
Recurrent urinary infections
-
Reduced urine drainage
-
Kidney function impairment
-
Infection behind an obstruction
A stone associated with infection and urinary obstruction can become a medical emergency.
Symptoms of a 14mm Kidney Stone
Some people with kidney stones have no symptoms.
When symptoms occur, they may include:
-
Severe flank pain
-
Pain in the lower back
-
Pain radiating toward the abdomen or groin
-
Blood in the urine
-
Nausea
-
Vomiting
-
Frequent urination
-
Burning while urinating
-
Difficulty passing urine
-
Restlessness during a severe pain episode
Symptoms depend more on the stone's location and whether it obstructs urine flow than on size alone.
When Is a 14mm Kidney Stone an Emergency?
Seek urgent medical attention if a suspected or known kidney stone is associated with:
-
Fever or chills
-
Severe or rapidly worsening pain
-
Persistent vomiting
-
Difficulty passing urine
-
Very low or no urine output
-
Severe weakness
-
Confusion
-
Known urinary obstruction
Fever with an obstructed urinary tract is particularly concerning because an infected obstructed kidney may require urgent drainage in addition to antibiotic treatment.
How Is a 14mm Kidney Stone Diagnosed?
Before choosing treatment, the stone should be accurately characterized.
Ultrasound
Ultrasound can identify:
-
Kidney stones
-
Hydronephrosis
-
Kidney swelling
-
Some urinary tract abnormalities
However, ultrasound may not provide all the information required for procedure planning.
Non-Contrast CT Scan
A non-contrast CT scan is commonly used when detailed assessment is needed.
It can help determine:
-
Exact stone size
-
Stone location
-
Number of stones
-
Degree of obstruction
-
Urinary tract anatomy
-
Stone density in appropriate settings
Blood Tests
Kidney-related blood tests may include:
-
Serum creatinine
-
eGFR
-
Electrolytes
-
Blood urea nitrogen
-
Complete blood count when infection is suspected
Urine Testing
Depending on the situation:
-
Urinalysis
-
Urine microscopy
-
Urine culture
-
Protein or albumin assessment when appropriate
A urine culture is particularly important when infection is suspected.
Treatment Options for a 14mm Kidney Stone
The best treatment depends on the stone's location and patient-specific factors.
1. Shock Wave Lithotripsy (SWL or ESWL)
Shock wave lithotripsy uses externally generated shock waves to break a kidney stone into smaller fragments.
The fragments may then pass through the urinary tract.
SWL may be considered for selected stones depending on:
-
Stone location
-
Stone density
-
Body habitus
-
Urinary anatomy
-
Stone burden
Not every 14mm stone is an ideal candidate for SWL.
Multiple treatment sessions may sometimes be necessary.
2. Ureteroscopy With Laser Lithotripsy
During ureteroscopy, a urologist passes a small scope through the urinary tract to reach the stone.
A laser can then fragment the stone into smaller pieces.
This approach may be suitable for stones located in the ureter or kidney depending on their characteristics.
A temporary ureteral stent may sometimes be placed before or after the procedure.
3. RIRS
Retrograde Intrarenal Surgery (RIRS) is a minimally invasive procedure used to access stones within the kidney.
A flexible ureteroscope is passed through the natural urinary passage into the kidney, where the stone can be fragmented using a laser.
RIRS may be considered for selected 14mm kidney stones, particularly when the stone's location or characteristics make other treatments less suitable.
The procedure is generally performed by a urologist.
4. PCNL
Percutaneous Nephrolithotomy (PCNL) involves creating a small access tract through the skin into the kidney to remove or fragment stones.
PCNL is commonly used for larger or complex stone burdens, although whether it is appropriate for a 14mm stone depends on its location, anatomy, composition, and other clinical factors.
The urologist determines whether PCNL offers an advantage over less invasive approaches.
Can Medicines Remove a 14mm Kidney Stone?
In most cases, medicines cannot dissolve a 14mm calcium-based kidney stone.
Medications may be used for:
-
Pain control
-
Nausea and vomiting
-
Selected ureteral stones to support passage
-
Prevention of future stones
-
Urinary infection when infection is present
A small number of uric acid stones may be dissolved with medically supervised urine alkalinization.
However, this approach is not appropriate for most stone types and should not be attempted without specialist guidance.
Can a 14mm Stone Be Treated Without Surgery?
The answer depends on what is meant by “without surgery.”
A 14mm kidney stone may sometimes be treated with SWL, which does not involve an incision or endoscopic removal.
However, observation alone is not necessarily appropriate if the stone is causing:
-
Persistent obstruction
-
Recurrent infection
-
Significant pain
-
Kidney-function deterioration
-
Other complications
The decision should be based on imaging and clinical assessment.
Which Treatment Is Best for a 14mm Kidney Stone?
There is no single best treatment for every 14mm stone.
Treatment selection depends on:
| Factor | Why It Matters |
|---|---|
| Stone location | Kidney and ureter stones may require different approaches |
| Stone density | Affects suitability for SWL |
| Stone anatomy | Determines accessibility |
| Obstruction | May require more urgent treatment |
| Infection | Changes treatment priorities |
| Kidney function | Important for planning and safety |
| Stone composition | Influences prevention and selected treatments |
| Previous procedures | May influence future treatment choice |
A urologist generally selects the procedure after reviewing imaging and clinical findings.
Recovery After 14mm Kidney Stone Treatment
Recovery depends on the treatment performed.
After SWL
Patients may experience:
-
Mild discomfort
-
Blood in the urine
-
Passage of stone fragments
-
Temporary urinary symptoms
Follow-up imaging may be required to determine whether fragments remain.
After Ureteroscopy or RIRS
Temporary symptoms may include:
-
Burning during urination
-
Frequent urination
-
Blood in the urine
-
Flank discomfort
If a stent is placed, urinary urgency or discomfort may continue until it is removed.
After PCNL
Recovery may take longer because the procedure involves percutaneous access to the kidney.
Follow-up depends on:
-
Residual stone fragments
-
Kidney function
-
Infection risk
-
Healing
-
Whether another procedure is required
Always follow the treating urologist's postoperative instructions.
What Should You Do After Removing a 14mm Stone?
Stone removal is only part of long-term management.
Patients with kidney stones may benefit from evaluation for factors that contribute to recurrence.
Depending on the clinical situation, this may include:
-
Stone analysis
-
Blood tests
-
Urine testing
-
Metabolic evaluation
-
Assessment of dietary factors
-
Review of fluid intake
-
Evaluation of calcium, uric acid, citrate, oxalate, and other risk factors when appropriate
Identifying the cause can help reduce the chance of developing another stone.
How to Prevent Future Kidney Stones
Preventive measures depend on stone type and metabolic findings.
General recommendations may include:
-
Maintain appropriate fluid intake as advised by your doctor.
-
Reduce excessive salt consumption.
-
Avoid unnecessary high-dose supplements.
-
Maintain a balanced diet.
-
Follow individualized dietary advice.
-
Maintain a healthy body weight.
-
Attend follow-up appointments.
-
Complete recommended metabolic testing if stones are recurrent.
Drinking more water is helpful for many stone-formers, but fluid goals should be individualized, particularly in people with advanced kidney or heart disease.

Frequently Asked Questions
Can a 14mm kidney stone pass naturally?
A 14mm stone is unlikely to pass naturally in many situations, particularly after entering the ureter. Specialist assessment is important to determine whether observation or active treatment is appropriate.
What is the best treatment for a 14mm kidney stone?
There is no universal best procedure. SWL, ureteroscopy with laser, RIRS, or PCNL may be considered depending on stone location, density, anatomy, obstruction, infection, and kidney function.
Can a 14mm kidney stone be dissolved?
Most calcium-based stones cannot be dissolved with medication. Selected uric acid stones may dissolve with medically supervised urine alkalinization.
Is RIRS suitable for a 14mm kidney stone?
RIRS can be an option for selected kidney stones around this size. Suitability depends on stone location, anatomy, density, and other patient-specific factors.
Is PCNL required for every 14mm stone?
No. PCNL is not automatically required for a 14mm stone. The urologist chooses the procedure based on stone burden, location, anatomy, and other clinical factors.
Can a 14mm stone cause hydronephrosis?
Yes. If a stone obstructs urine flow, it can cause hydronephrosis. Persistent obstruction can damage kidney function if not appropriately managed.
Can I treat a 14mm stone with home remedies?
Home remedies cannot reliably remove a 14mm stone. Adequate hydration may support general urinary health, but it should not replace specialist evaluation or treatment when a large stone is obstructing the urinary tract.
Conclusion
Kidney stone 14mm treatment requires careful assessment because a stone of this size is relatively large and is unlikely to pass naturally in many situations. Treatment may involve SWL, ureteroscopy with laser lithotripsy, RIRS, or PCNL depending on the stone's location, density, anatomy, symptoms, obstruction, infection status, and kidney function.
Medicines generally do not dissolve common calcium-based stones, although selected uric acid stones may be treated with medically supervised urine alkalinization. Importantly, fever associated with urinary obstruction requires urgent medical attention.
