Kidney Stone Pain Location: Where Does It Hurt?

Kidney stone pain can start suddenly in the side or back and may move toward the lower abdomen, pelvis or groin as the stone travels through the urinary tract. Knowing the typical pain pattern can help you recognize symptoms, but pain location alone cannot confirm a kidney stone.

Quick Answer: Where Is Kidney Stone Pain Located?

Kidney stone pain most commonly starts in the side or back below the ribs, an area called the flank. As a stone moves through the ureter, the pain may travel toward the lower abdomen, pelvis or groin.

Kidney stone pain can be sharp, severe, cramping or wave-like. Nausea, vomiting, blood in the urine, burning urination or urinary urgency may also occur.

However, pain location alone cannot confirm a kidney stone. Other conditions can cause similar symptoms, so medical evaluation may be necessary.

๐Ÿšจ When Kidney Stone Pain Needs Urgent Medical Attention

Seek urgent medical care if suspected kidney stone pain occurs with:

  • Fever or chills
  • Severe or uncontrolled pain
  • Persistent vomiting
  • Difficulty passing urine or inability to urinate
  • Feeling very weak, confused or seriously unwell

A blocked urinary tract together with infection can become a serious medical problem and requires prompt medical assessment.

Where Is Kidney Stone Pain Located?

Kidney stone pain is commonly felt on one side of the body in the flank, the area between the lower ribs and the hip.

The location can change as a stone travels from the kidney into the ureter.

Typical pain pattern:

Side / back below ribs โ†’ Flank โ†’ Lower abdomen โ†’ Pelvis / groin

Kidney Stone Pain Location Chart

Possible Stone Location Where Pain May Be Felt Possible Associated Symptoms
Kidney Side or back below the ribs Flank discomfort
Upper ureter Flank or side of the back Severe or wave-like pain
Middle ureter Side or lower abdomen Pain may move downward
Lower ureter Lower abdomen or groin Urinary urgency or discomfort
Near bladder Pelvis or groin Frequent urge to urinate

This pattern can help explain kidney stone pain, but it does not allow a person to determine the exact stone location or size without appropriate medical assessment and imaging.

What Does Kidney Stone Pain Feel Like?

Kidney stone pain may feel different from ordinary muscle or joint pain.

7 Common Kidney Stone Pain Locations

1. Flank or Side

The flank is the area on either side of the back below the ribs and above the hip. This is one of the most common areas associated with kidney stone pain.

2. Back Below the Ribs

Kidney stones can cause pain around the back below the ribs. However, other kidney, abdominal and musculoskeletal problems can cause pain in this area.

3. Lower Abdomen

As a stone travels down the ureter, pain may shift toward the lower abdomen and can sometimes be mistaken for digestive or abdominal pain.

4. Groin

Pain can radiate from the flank or lower abdomen toward the groin when a stone moves farther down the ureter.

5. Pelvic Area

A lower ureteral stone can cause pelvic discomfort and may be associated with urinary urgency or frequency.

6. Testicle in Men

Pain from a lower ureteral stone may radiate toward the testicle. Sudden severe testicular pain needs urgent evaluation.

7. Bladder-Area Discomfort

When a stone approaches the bladder, urinary urgency, frequency or burning may occur along with lower abdominal or pelvic discomfort.

Why Does Kidney Stone Pain Move?

The kidneys and bladder are connected by narrow tubes called ureters.

When a stone leaves the kidney and enters the ureter, it can interfere with urine flow and trigger contractions of the ureter. This can produce intense, wave-like pain.

As the stone travels downward, the perceived location of pain may also change.

Important: Pain moving from the flank toward the lower abdomen or groin can occur with a moving kidney stone, but this symptom alone cannot confirm the diagnosis.

Kidney Stone Pain vs Back Pain

Feature Kidney Stone Pain Common Musculoskeletal Back Pain
Typical location Flank or side below ribs Back or lower back
Pain pattern May be severe and wave-like Often aching or stiff
Radiation May move toward abdomen or groin Often remains localized, although exceptions occur
Urinary symptoms May occur Usually absent
Blood in urine Can occur Not typical
Nausea/vomiting Can occur Less typical

This comparison is only a general guide. Back pain has many possible causes, and a healthcare professional may need to evaluate the symptoms.

Can Kidney Stones Cause Right-Sided Pain?

Yes. A stone affecting the right kidney or right ureter can cause pain on the right side or right flank.

Possible pattern:

Right flank โ†’ Right abdomen โ†’ Right groin

However, right-sided abdominal pain can also occur with conditions such as appendicitis, gallbladder disease and gastrointestinal problems. Do not assume that right-sided pain is a kidney stone without appropriate evaluation.

Can Kidney Stones Cause Left-Sided Pain?

Yes. A stone affecting the left kidney or left ureter can cause left-sided flank pain.

The pain may move toward the left lower abdomen or groin as the stone travels through the ureter.

Kidney Stone Pain in Men

Men may experience kidney stone pain in the:

Sudden or severe testicular pain should not automatically be attributed to kidney stones because other urgent conditions can cause similar symptoms.

Kidney Stone Pain in Women

Women may experience kidney stone pain in the flank, back, lower abdomen, pelvis or groin.

Because pelvic and abdominal conditions can produce similar symptoms, pain location alone cannot confirm a kidney stone.

If pregnancy is possible, tell your healthcare professional because pregnancy affects the choice of diagnostic imaging.

Kidney Stone Symptoms Besides Pain

Urinary Symptoms

Other Symptoms

Possible Infection Symptoms

Can You Have a Kidney Stone Without Blood in Urine?

Yes.

Visible blood does not have to be present for someone to have a kidney stone. Blood may sometimes be detected only through urine testing.

No visible blood does not completely rule out a kidney stone.

Does Pain Location Tell You the Size of a Kidney Stone?

No.

Pain intensity and location cannot reliably tell you how large a kidney stone is.

Imaging may be used to determine:

How Are Kidney Stones Diagnosed?

1. Urine Test

A urine test can check for blood, signs of infection and other abnormalities.

2. Blood Tests

Blood tests may help assess kidney function, infection and certain factors associated with stone formation.

3. Ultrasound

Ultrasound can identify many kidney stones and can also show evidence of urinary obstruction.

4. CT Scan

CT imaging can provide detailed information about stone size, location and obstruction when clinically appropriate.

Kidney Stone Warning Signs You Should Not Ignore

๐Ÿšจ Severe or uncontrolled pain
๐ŸŒก๏ธ Fever or chills
๐Ÿคฎ Persistent vomiting
๐Ÿšฝ Unable to pass urine
๐Ÿฉธ Blood in urine
๐Ÿ˜ต Feeling faint or seriously unwell
๐Ÿ”ฅ Severe urinary symptoms with fever
โš ๏ธ Suspected infected urinary obstruction

How Are Kidney Stones Treated?

Treatment depends on the stone's size, location, symptoms, degree of obstruction, kidney function and whether infection is present.

Small Kidney Stones

Some smaller stones pass naturally. Depending on the individual situation, a healthcare professional may recommend appropriate pain management, hydration advice and observation.

Shock-Wave Lithotripsy

Shock-wave lithotripsy uses focused shock waves to break selected kidney stones into smaller fragments.

Ureteroscopy

During ureteroscopy, a thin instrument is passed through the urinary tract to locate and treat a stone.

PCNL

Percutaneous nephrolithotomy, or PCNL, may be used for larger or complex kidney stones. It involves accessing the kidney through a small opening in the back.

The appropriate treatment depends on the individual stone and clinical situation.

How to Reduce the Risk of Future Kidney Stones

Prevention depends on the type of kidney stone and individual risk factors.
