kidney stones can sometimes cause frequent urination, particularly when a stone moves from the kidney into the ureter and approaches the bladder.
A stone can irritate the urinary tract and create sensations such as:
-
Frequent urge to urinate
-
Urinating small amounts
-
Urinary urgency
-
Burning during urination
-
Lower abdominal discomfort
-
Flank or back pain
-
Blood in the urine
However, frequent urination does not automatically mean that a kidney stone is present. Urinary infections, diabetes, an enlarged prostate, overactive bladder and other conditions can cause similar symptoms.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation for kidney stones, urinary symptoms and related kidney conditions.
Why Do Kidney Stones Cause Frequent Urination?
The effect of a kidney stone depends largely on its location.
A stone that remains inside the kidney may cause no urinary symptoms at all.
When it travels down the ureter and reaches the lower part of the urinary tract, it may irritate nearby tissues and create a strong sensation that the bladder needs to empty.
This can result in:
-
Frequent trips to the bathroom
-
Urgency
-
Small-volume urination
-
Discomfort while passing urine
Therefore, frequent urination with a kidney stone may be more noticeable when the stone is close to the bladder.
Other Symptoms That May Occur With Kidney Stones
Frequent urination may occur alongside other stone-related symptoms.
Flank Pain
Pain may occur in the side or back and can move toward the lower abdomen or groin.
Renal Colic
A moving stone may cause severe pain that comes in waves.
Blood in Urine
Stones can irritate the urinary tract and cause microscopic or visible blood in urine.
Nausea and Vomiting
Severe renal colic can stimulate nausea or vomiting.
Burning Urination
A stone close to the bladder or urethra may cause discomfort during urination.
Urinary Urgency
Some patients feel an intense need to urinate even when the bladder contains only a small amount of urine.
Frequent Urination Does Not Always Mean Kidney Stones
There are many possible causes of urinary frequency.
Urinary Tract Infection
A UTI can cause:
-
Frequent urination
-
Urgency
-
Burning
-
Lower abdominal discomfort
-
Cloudy or foul-smelling urine
If the infection reaches the kidneys, fever and flank pain may develop.
Diabetes
High blood glucose can increase urine production and lead to frequent urination.
Excessive thirst may occur at the same time.
Overactive Bladder
An overactive bladder can cause urgency and frequent urination without a kidney stone.
Enlarged Prostate
In men, an enlarged prostate can interfere with normal bladder emptying and produce:
-
Frequent urination
-
Night-time urination
-
Weak urine stream
-
Difficulty starting urination
-
Urgency
Excessive Fluid or Caffeine Intake
Drinking large amounts of fluid or consuming significant quantities of caffeine can increase urinary frequency.
Because these conditions can resemble stone-related symptoms, testing may be necessary.
Does the Location of a Kidney Stone Matter?
Yes.
The symptoms caused by a stone can vary depending on where it is located.
Stone Inside the Kidney
A kidney stone may remain silent and be discovered during an ultrasound or other imaging examination.
Stone in the Ureter
As a stone enters the ureter, it may cause severe flank pain and renal colic.
Stone Near the Bladder
A lower ureteric stone may cause:
-
Frequent urination
-
Urgency
-
Lower abdominal discomfort
-
Burning while urinating
This is one reason a patient with a small lower ureteric stone may experience significant urinary symptoms.
Can Kidney Stones Cause a Urinary Infection?
Kidney stones can be associated with urinary infections, particularly when they obstruct normal urine flow.
An infected obstructed urinary system can become serious.
Warning symptoms include:
-
Fever
-
Chills
-
Flank pain
-
Burning urination
-
Nausea
-
Vomiting
-
Feeling very unwell
If you have a suspected kidney stone and develop fever or chills, seek prompt medical attention.
How Are Kidney Stones and Frequent Urination Diagnosed?
The evaluation depends on the patient's symptoms and medical history.
Urine Examination
Urine testing can look for:
-
Blood
-
White blood cells
-
Protein
-
Crystals
-
Signs of infection
A urine culture may be required when infection is suspected.
Blood Tests
Doctors may assess:
-
Serum creatinine
-
eGFR
-
Urea
-
Electrolytes
-
Blood count
-
Other tests when indicated
These tests can help determine whether kidney function is affected.
Ultrasound
Ultrasound can help identify:
-
Kidney stones in many cases
-
Kidney swelling
-
Hydronephrosis
-
Structural abnormalities
-
Some urinary obstructions
CT Scan
A CT scan may be recommended when more detailed assessment is necessary, particularly when the location or size of a stone needs clarification.
How Are Kidney Stones Treated?
Treatment depends on the stone's size, location, symptoms and complications.
Observation
Some small stones can pass naturally.
A doctor may recommend observation when there is a reasonable chance of spontaneous passage and no serious complication.
Medication
Selected patients may receive:
-
Pain-relief medication
-
Medicines that may facilitate passage of certain ureteric stones
-
Antibiotics when a bacterial infection is diagnosed
Medication should be prescribed according to the patient's condition.
Shock-Wave Lithotripsy
Shock waves can be used to break selected stones into smaller fragments.
Ureteroscopy
A thin instrument can be passed through the urinary tract to reach a stone. The stone may be fragmented, including with laser energy, and removed.
Percutaneous Nephrolithotomy
PCNL may be recommended for selected larger or complex kidney stones.
What If a Kidney Stone Is Blocking Urine?
An obstructing stone requires careful assessment.
If obstruction is severe, prolonged or associated with infection, urgent treatment may be necessary.
Treatment may involve restoring urine drainage and subsequently treating or removing the stone.
Do not assume that drinking large amounts of water will clear a significant obstruction.
Can Kidney Stones Cause Frequent Urination at Night?
They can, particularly when a stone is located near the lower urinary tract or when urinary irritation is present.
However, night-time urination, also called nocturia, has many other causes, including:
-
Excess evening fluid intake
-
Diabetes
-
Prostate enlargement
-
Overactive bladder
-
Certain medicines
-
Heart or kidney conditions
Persistent nocturia should therefore be evaluated rather than automatically attributed to kidney stones.
How Can You Reduce the Risk of Future Kidney Stones?
Stone prevention depends on the type of stone and individual risk factors.
General measures may include:
Maintain Appropriate Hydration
Adequate fluid intake can help reduce the concentration of stone-forming substances in urine.
The required amount should be individualized, especially for people with reduced kidney function or heart disease.
Limit Excess Salt
High sodium intake can increase urinary calcium in some individuals and contribute to stone formation.
Follow an Appropriate Diet
Depending on stone composition and urine chemistry, dietary recommendations may involve calcium, oxalate, animal protein, sodium or other factors.
Do not unnecessarily eliminate dietary calcium unless advised by a healthcare professional.
Investigate Recurrent Stones
People who repeatedly develop stones may benefit from metabolic evaluation and stone analysis.
This can help identify preventable risk factors.
Can Kidney Stones Damage Kidney Function?
Small uncomplicated stones may pass without permanent kidney damage.
However, prolonged obstruction, recurrent infections or severe stone disease can potentially affect kidney function.
People with:
-
A single functioning kidney
-
Bilateral stones
-
Recurrent obstruction
-
Recurrent urinary infections
-
Existing chronic kidney disease
may require closer monitoring.
Should You Drink More Water When You Have a Kidney Stone?
Adequate hydration can be important in kidney stone prevention and in selected cases of uncomplicated stones.
However, forcing excessive water intake is not recommended as a general treatment for severe stone pain or obstruction.
Large amounts of fluid may worsen discomfort if urine flow is significantly blocked.
Follow the fluid advice provided by your healthcare professional.
When Should You See a Doctor?
Consult a healthcare professional if frequent urination is:
-
Persistent
-
Recurrent
-
Associated with pain
-
Associated with blood in urine
-
Accompanied by burning
-
Associated with fever
-
Accompanied by flank pain
-
Associated with reduced urine output
A medical evaluation can determine whether the cause is a stone, infection or another urinary condition.
When Is Kidney Stone-Related Frequent Urination an Emergency?
Seek urgent medical care if urinary symptoms occur with:
-
High fever or chills
-
Severe flank pain
-
Persistent vomiting
-
Very little or no urine
-
Severe weakness
-
Confusion
-
Fainting
-
Known urinary obstruction
-
A single functioning kidney with significant symptoms
An obstructed urinary system with infection can become a serious medical emergency.

Frequently Asked Questions
Can kidney stones cause frequent urination?
Yes. A stone, particularly one located in the lower ureter near the bladder, can irritate the urinary tract and cause urgency and frequent urination.
Is frequent urination always a sign of kidney stones?
No. UTIs, diabetes, prostate enlargement, overactive bladder, excess fluid intake and several other conditions can cause frequent urination.
Can kidney stones cause burning while urinating?
Yes. A stone near the bladder or lower urinary tract may cause irritation and discomfort during urination. A UTI can cause similar symptoms.
Can a kidney stone cause frequent urination without severe pain?
Yes. Some stones, especially those near the bladder, may cause urinary urgency or frequency with relatively mild pain.
Does frequent urination mean my kidneys are failing?
Not necessarily. Frequent urination alone does not establish kidney failure. Kidney function is evaluated using blood tests such as creatinine and eGFR, along with urine testing and other investigations when appropriate.
Can drinking more water remove kidney stones?
Some small stones can pass naturally, and adequate hydration may support urinary stone prevention. However, excessive water is not a substitute for medical treatment when there is significant obstruction or another complication.
When should frequent urination with kidney stones be treated urgently?
Seek urgent care when frequent urination occurs with fever, chills, severe flank pain, persistent vomiting, very little urine or known urinary obstruction.
Conclusion
Kidney stones and frequent urination can occur together, especially when a stone moves into the lower ureter and irritates the urinary tract near the bladder. Urinary urgency, frequent small-volume urination, burning and lower abdominal discomfort may accompany a stone.
However, frequent urination has many other possible causes, including urinary infections, diabetes, prostate problems and bladder disorders. Proper evaluation with urine testing, kidney-function tests and appropriate imaging can help establish the cause.
Most importantly, fever, chills, severe pain, vomiting or reduced urine output should not be ignored, particularly when a urinary stone is known or suspected.
For specialist evaluation of kidney stones, urinary symptoms and kidney health, consult Dr. Sandip Prabhakar Bhurke at Prabhakar Bhurke Clinic.
