A kidney stone can cause pain or pressure in the abdomen, side, pelvis or groin, particularly when the stone moves from the kidney into the ureter.

However, kidney stones do not usually directly cause constipation or physically press on the bowel.

The urinary tract and bowel are located close to each other in the abdomen and pelvis. Pain from a ureteral stone can therefore sometimes feel like pressure in the lower abdomen or pelvic region and may be mistaken for a bowel problem.

Kidney stones commonly cause sharp pain in the back, side, lower abdomen or groin. The pain may come in waves and can change location as the stone moves.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation of kidney stones, urinary obstruction and related kidney-function problems.

Why Can a Kidney Stone Feel Like Bowel Pressure?

The ureters travel from the kidneys toward the bladder through the abdomen and pelvis.

When a stone enters a ureter, it can cause:

• Spasm of the ureter

• Partial or complete urinary obstruction

• Sudden flank pain

• Lower abdominal discomfort

• Pelvic pressure

• Groin pain

• Nausea or vomiting

• Urinary urgency

Because the lower ureter lies close to pelvic organs and bowel structures, discomfort may sometimes be perceived as pressure in the bowel or rectal region.

The location of pain can change as the stone moves.

This does not necessarily mean that the stone is pressing directly against the intestine.

Can Kidney Stones Cause Constipation?

Usually, kidney stones are not a direct cause of constipation.

Constipation has many possible causes, including:

• Low dietary fiber

• Inadequate fluid intake

• Reduced physical activity

• Certain medicines

• Changes in routine

• Some metabolic conditions

• Gastrointestinal disorders

NIDDK defines constipation using symptoms such as infrequent bowel movements, hard or difficult-to-pass stools and a feeling that the bowel has not completely emptied.

A person with a kidney stone can have constipation at the same time, but the two problems may be separate.

Why Might Someone With a Kidney Stone Feel Constipated?

Several situations can make bowel discomfort occur alongside a kidney stone.

Severe Pain

Kidney stone pain can be intense. Pain and physical discomfort may alter normal eating, movement and bowel habits.

Pain Medicines

Some stronger pain medicines, particularly opioid-type medicines, can contribute to constipation. NIDDK lists narcotic pain medicines among medicines that may worsen constipation.

Reduced Activity

When a person is experiencing renal colic, they may move less than usual. Reduced physical activity can contribute to constipation.

Reduced Food or Fluid Intake

Nausea and vomiting may make it difficult to eat or drink normally.

However, fluid intake should not be increased excessively in someone with kidney failure, heart disease or another condition requiring fluid restriction.

Two Conditions at the Same Time

A patient may simply have both a kidney stone and constipation.

Therefore, bowel pressure should not automatically be attributed to the stone.

Kidney Stone Pressure vs Constipation: How Are They Different?

The symptoms can overlap, but certain features may provide clues.

Feature	Kidney stone	Constipation
Typical pain	Side, back, lower abdomen or groin	Lower abdomen or generalized abdominal discomfort
Pain pattern	May come in waves	Often associated with bowel movements
Urinary symptoms	May occur	Usually absent
Blood in urine	Can occur	Not typical
Nausea or vomiting	Can occur	Can occur with significant constipation
Hard stools	Not a typical stone symptom	Common
Infrequent bowel movements	Not a typical stone symptom	Common
Urinary urgency	Can occur	Not typical
Fever	May occur if infection is present	May occur with certain bowel conditions

These patterns are only general clues. A proper medical assessment may be necessary when symptoms overlap.

Can a Kidney Stone Cause Lower Abdominal Pressure?

Yes, a ureteral stone can produce lower abdominal or pelvic discomfort.

As a stone moves toward the bladder, pain may shift from the flank toward the lower abdomen, groin or pelvic area. Urinary urgency and frequent urination may also occur, particularly when the stone is near the lower ureter.

This may be described by a patient as:

• Pressure in the lower abdomen

• Pressure near the bladder

• Pelvic discomfort

• A sensation of needing to pass urine

• Discomfort near the groin

These symptoms do not necessarily indicate a bowel disorder.

Can a Kidney Stone Cause Pressure Near the Rectum?

A lower ureteral stone can sometimes produce pain that is perceived in nearby pelvic or groin areas.

However, rectal pressure is not a specific symptom of kidney stones.

Rectal pressure can also occur with:

• Constipation

• Hemorrhoids

• Pelvic-floor problems

• Gastrointestinal disorders

• Rectal or colorectal conditions

• Other pelvic conditions

If rectal pressure persists or is associated with bleeding, severe abdominal pain, vomiting or inability to pass stool or gas, medical evaluation is important.

What Other Symptoms Suggest a Kidney Stone?

Bowel pressure becomes more suspicious for a urinary stone when it occurs together with typical urinary or renal-colic symptoms.

These may include:

• Sudden flank or side pain

• Pain spreading toward the lower abdomen or groin

• Blood in urine

• Burning during urination

• Frequent urination

• Urgency to urinate

• Passing only a small amount of urine

• Nausea

• Vomiting

Kidney stones can also cause cloudy or foul-smelling urine.

When Bowel Pressure Could Be an Emergency

Bowel pressure alone is usually not enough to determine whether a kidney stone is dangerous.

However, kidney stone symptoms combined with signs of urinary obstruction or infection require prompt medical attention.

Seek urgent medical care if you experience:

• Fever or chills

• Severe or worsening flank pain

• Persistent vomiting

• Very little or no urine

• Difficulty passing urine

• Blood in the urine

• Severe weakness

• Confusion

• Rapid deterioration

A stone that obstructs urine flow can cause significant complications, including urinary infection and loss of kidney function if not appropriately managed.

What If a Kidney Stone and Constipation Occur Together?

Both problems should be evaluated according to their individual symptoms.

For constipation, a doctor may ask about:

• Frequency of bowel movements

• Stool consistency

• Abdominal discomfort

• Diet

• Fluid intake

• Physical activity

• Medicines

• Previous bowel problems

For a suspected kidney stone, evaluation may include:

• Urinalysis

• Blood tests

• Kidney-function testing

• Ultrasound

• CT imaging when appropriate

Urine and blood tests, along with imaging, can help identify a stone and determine whether urinary obstruction is present.

How Are Kidney Stones Diagnosed?

The doctor may begin with the patient's symptoms and medical history.

Urine Examination

Urinalysis can help identify:

• Blood

• White blood cells

• Bacteria

• Crystals

• Other abnormalities

Blood Tests

Depending on the situation, testing may include:

• Creatinine

• eGFR

• Electrolytes

• Blood count

• Other relevant parameters

Ultrasound

Ultrasound can help identify many stones and may show urinary tract dilation or obstruction.

CT Scan

When more detailed assessment is required, CT imaging can help determine:

• Stone size

• Stone location

• Number of stones

• Degree of obstruction

• Other possible causes of abdominal or pelvic symptoms

The choice of imaging depends on symptoms, age, pregnancy status, kidney function and the clinical situation.

Can Treating the Kidney Stone Relieve the Pressure?

If the pressure or pain is caused by the stone's movement or urinary obstruction, treating the stone may improve those symptoms.

Treatment depends on the stone's:

• Size

• Location

• Composition

• Degree of obstruction

• Symptoms

• Infection status

• Effect on kidney function

Small stones may sometimes pass without a procedure.

Larger, obstructing or persistently painful stones may require active treatment. Options can include ureteroscopy with laser treatment, shock wave lithotripsy or percutaneous nephrolithotomy for selected larger stones.

Does Drinking More Water Remove Bowel Pressure From a Kidney Stone?

Not necessarily.

Adequate hydration can be important for many people with kidney stones, but drinking excessive amounts of water does not force an obstructed stone through the ureter.

If someone is vomiting, has kidney failure, heart disease or has been given a fluid restriction, fluid intake needs to be individualized.

Follow the fluid recommendation provided by the treating healthcare professional.

What Can Help Prevent Future Kidney Stones?

Preventive treatment depends on the type of stone and the reason it formed.

A specialist may recommend:

• Appropriate fluid intake

• Reducing excessive dietary sodium

• Individualized dietary changes

• Stone analysis

• Metabolic evaluation in selected patients

• Appropriate preventive medication

• Treatment of recurrent urinary infections

• Follow-up imaging when required

Drinking enough fluid is an important part of preventing many kidney stones, but the appropriate amount varies according to health conditions and kidney function.

What Should You Do If Kidney Stone Pain Feels Like a Bowel Problem?

Do not assume that abdominal or bowel pressure is simply constipation if urinary symptoms are also present.

Consider medical evaluation if you have:

• Flank pain with abdominal pressure

• Blood in urine

• Urinary urgency

• Painful urination

• Repeated vomiting

• Recurrent stone history

• Known urinary obstruction

• Reduced urine output

A correct diagnosis can prevent unnecessary delay in treating either a urinary or gastrointestinal condition.

Kidney Stone and Bowel Pressure Evaluation at Prabhakar Bhurke Clinic

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized assessment for patients with kidney stones, urinary symptoms and kidney-function concerns.

Depending on the clinical presentation, evaluation may include:

• Review of abdominal, flank and pelvic symptoms

• Kidney-function assessment

• Urine examination

• Review of ultrasound or CT reports

• Assessment of urinary obstruction

• Evaluation of recurrent kidney stones

• Review of medicines that may affect symptoms or bowel habits

• Assessment of associated kidney disease

• Coordination with a urologist or other specialist when a procedure or non-kidney cause requires additional care

The objective is to determine whether the bowel pressure is related to a urinary stone, constipation or another abdominal or pelvic condition.

Frequently Asked Questions

Can kidney stones cause bowel pressure?

Kidney stones can cause lower abdominal or pelvic pain and discomfort that may feel like pressure near the bowel. However, they do not usually directly compress the bowel or cause constipation.

Can kidney stones make you feel like you need to poop?

Pelvic or lower abdominal discomfort from a ureteral stone can create unusual pressure sensations. However, the feeling of needing to pass stool can also result from constipation or other gastrointestinal conditions.

Do kidney stones cause constipation?

Constipation is not a typical direct symptom of kidney stones. It may occur at the same time or be influenced by factors such as reduced activity, changes in diet and certain pain medicines.

Can a kidney stone cause pressure in the lower abdomen?

Yes. As a stone travels through the ureter, pain can shift from the flank toward the lower abdomen, pelvis or groin.

Can a kidney stone cause rectal pressure?

A lower urinary tract stone may produce discomfort perceived in nearby pelvic areas, but rectal pressure is not specific to kidney stones. Persistent rectal pressure should be evaluated for other causes.

What symptoms mean that a kidney stone needs urgent treatment?

Severe pain with fever or chills, persistent vomiting, difficulty passing urine, very low urine output or rapid worsening can indicate a complication requiring urgent medical assessment.

Can constipation and kidney stones occur together?

Yes. A person can have both conditions simultaneously. The symptoms should be assessed separately rather than assuming that one condition explains everything.

Conclusion

Kidney stones and bowel pressure can sometimes be connected through the way ureteral pain is perceived. A stone moving through the urinary tract can cause discomfort in the flank, lower abdomen, pelvis or groin, which may feel similar to bowel pressure.

However, kidney stones are not a usual direct cause of constipation. Hard stools, infrequent bowel movements or difficulty passing stool may point toward a separate gastrointestinal problem.

When bowel pressure occurs with flank pain, urinary urgency, blood in urine, painful urination or vomiting, kidney stone evaluation may be appropriate. Urgent attention is particularly important when fever, chills, severe pain, reduced urine output or difficulty passing urine occurs.

Accurate diagnosis helps determine whether symptoms are caused by a kidney stone, constipation, urinary obstruction or another abdominal or pelvic condition.
