Introduction
Renal colic is one of the most severe types of pain experienced by patients with kidney stones. It occurs when a stone blocks the flow of urine through the urinary tract, causing intense pain that often begins suddenly and may radiate from the back to the lower abdomen or groin.
Renal colic is considered a medical emergency because the pain can be extremely severe, and untreated urinary obstruction may lead to kidney damage or infection. Fortunately, with prompt diagnosis and appropriate treatment, most patients experience significant relief and successful management of the underlying cause.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive evaluation, advanced kidney stone management, personalized treatment plans, and long-term kidney care to help patients recover quickly and prevent future stone formation.
What Is Renal Colic?
Renal colic refers to the sudden, severe pain caused by blockage of urine flow, most commonly due to a kidney stone moving through the urinary tract.
The pain develops because:
-
Urine backs up behind the obstruction.
-
Pressure increases inside the kidney.
-
The ureter (the tube connecting the kidney to the bladder) goes into spasm.
Renal colic requires medical evaluation to identify the cause and determine the most appropriate treatment.
Common Causes of Renal Colic
The most common cause is kidney stones, but other conditions may also block urine flow.
Possible causes include:
-
Kidney stones
-
Ureteric stones
-
Blood clots
-
Narrowing of the ureter
-
Urinary tract obstruction
-
Rarely, tumors affecting the urinary tract
Kidney stones remain the leading cause of renal colic.
Symptoms of Renal Colic
Symptoms often begin suddenly and may include:
-
Severe pain in the side (flank pain)
-
Lower back pain
-
Pain radiating to the lower abdomen or groin
-
Pain that comes in waves
-
Blood in the urine
-
Burning during urination
-
Frequent urge to urinate
-
Nausea and vomiting
-
Restlessness due to severe pain
If fever or chills accompany renal colic, it may indicate a kidney infection requiring urgent treatment.
When Should You Seek Immediate Medical Attention?
Seek emergency medical care if renal colic occurs with:
-
Fever or chills
-
Persistent vomiting
-
Severe uncontrolled pain
-
Difficulty passing urine
-
Reduced urine output
-
Blood in urine with severe pain
-
One functioning kidney
-
Pregnancy with severe flank pain
Prompt treatment helps prevent kidney damage and serious complications.
How Is Renal Colic Diagnosed?
At Prabhakar Bhurke Clinic, our super specialist nephrologist performs a detailed evaluation to identify the cause of pain and assess kidney function.
Medical History and Physical Examination
The doctor evaluates:
-
Location of pain
-
Severity and duration
-
Previous kidney stone history
-
Urinary symptoms
-
Medical history
-
Current medications
Blood Tests
Investigations may include:
-
Serum Creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Blood Urea Nitrogen (BUN)
-
Electrolytes
-
Complete Blood Count (CBC)
These tests assess kidney function and detect infection.
Urine Tests
Urine investigations help detect:
-
Blood
-
Infection
-
Crystals
-
Protein
-
Stone-related abnormalities
Imaging Studies
Imaging helps locate stones and determine their size.
Common investigations include:
-
Kidney Ultrasound
-
Non-contrast CT Scan (CT KUB)
-
X-ray in selected cases
These tests help guide treatment decisions.
Renal Colic Pain Treatment
Treatment depends on:
-
Stone size
-
Stone location
-
Severity of symptoms
-
Presence of infection
-
Kidney function
Pain Management
The first priority is controlling pain.
Your doctor may prescribe medicines that help relieve pain and reduce ureteric spasm.
Pain relief should always be supervised by a healthcare professional, especially in patients with kidney disease.
Hydration
Adequate hydration may help in selected patients, particularly with small stones.
However, excessive fluid intake during severe obstruction is not always recommended and should only be done under medical guidance.
Medical Expulsive Therapy
Small stones may pass naturally.
Your nephrologist may prescribe medications that help relax the ureter and improve the chances of stone passage.
Treatment of Infection
If renal colic is associated with urinary tract infection or kidney infection, prompt antibiotic treatment is essential.
Infected urinary obstruction requires urgent medical attention.
Surgical Treatment for Renal Colic
Larger stones or persistent obstruction may require minimally invasive procedures.
Ureteroscopy (URS)
A thin telescope is passed through the urinary tract to remove or break the stone.
Laser Lithotripsy
Laser energy is used to fragment stones into smaller pieces that can pass naturally.
Laser stone removal is highly effective for many ureteric stones.
Extracorporeal Shock Wave Lithotripsy (ESWL)
Shock waves are used to break selected kidney stones into smaller fragments.
Not all stones are suitable for ESWL.
Percutaneous Nephrolithotomy (PCNL)
Large or complex kidney stones may require PCNL, a minimally invasive procedure performed through a small incision.
Preventing Future Kidney Stones
After treatment, preventing recurrence is important.
Your nephrologist may recommend:
-
Drinking adequate fluids (as medically advised)
-
Reducing salt intake
-
Maintaining a healthy weight
-
Limiting foods that increase stone risk based on stone type
-
Managing diabetes and blood pressure
-
Regular kidney check-ups
-
Stone analysis when available
A personalized prevention plan helps reduce future stone formation.
Possible Complications if Left Untreated
Untreated renal colic may lead to:
-
Persistent urinary obstruction
-
Kidney infection
-
Kidney swelling (Hydronephrosis)
-
Reduced kidney function
-
Acute kidney injury
-
Permanent kidney damage in severe cases
Early treatment greatly reduces these risks.
When Should You Consult a Nephrologist?

-
Severe flank pain
-
Recurrent kidney stones
-
Blood in urine
-
High creatinine levels
-
Reduced eGFR
