Quick Answers
Can kidney stones be treated?
Treatment depends on stone size, type, location, symptoms, and whether complications develop.
Can kidney stones pass naturally?
Smaller stones may pass naturally with hydration, medicines, and appropriate medical monitoring.

Untreated stones can cause urinary blockage, infections, persistent pain, and kidney damage.
When should someone seek medical care?

What Are Kidney Stones?
Kidney stones are hard mineral deposits that form inside the kidneys when substances in urine become concentrated. They may remain in the kidney or move into the urinary tract, causing pain, blockage, or difficulty passing urine.
Key points:
- Urination may become painful
- Blood may appear in urine
- Dehydration increases stone formation risk
- Nausea may accompany severe episodes
Types of Kidney Stones
Calcium Stones
Calcium stones develop when calcium combines with oxalate or phosphate in urine.
Uric Acid Stones
Uric acid stones develop when persistently acidic urine promotes crystal formation.
Struvite Stones
Struvite stones develop when urinary infections create alkaline conditions for growth.
Cystine Stones
Cystine stones develop because inherited cystinuria causes excess cystine in urine.
Symptoms Of Kidney Stones

Kidney Stone Patterns, Diagnosis & Treatment Approach
| Pattern | Type | First-Line Approach |

Expected Outcome |
|---|---|---|---|---|
| Less than 4 mm | Small stone | Hydration and medication | Failure to pass naturally | Likely natural passage |
| 4–6 mm | Moderate stone | Medication or observation | Persistent stone or symptoms | Possible assisted passage |
| 6–10 mm | Larger stone | Urological evaluation | Unlikely natural passage | Removal with appropriate procedure |
| More than 10 mm | Large stone | Specialist intervention | Significant obstruction or complexity | Procedural stone clearance |
Procedure & Recovery: What to Expect
Non-invasive (Shock Wave Lithotripsy (ESWL))
- Stone fragments may pass through urine afterwards.

Frequently Asked Questions
Why do kidney stones cause nausea and vomiting?
When a blockage stretches the kidney, shared nerve pathways between the urinary and digestive systems can trigger nausea, vomiting, and other stomach-related symptoms.
Why is a 24-hour urine test done after stones?
It measures daily levels of calcium, oxalate, uric acid, citrate, sodium, and urine volume to identify metabolic factors that may contribute to future formation.
Can untreated kidney stones cause permanent kidney damage?
A prolonged blockage can cause urine buildup, kidney swelling, tissue damage, and gradual loss of function, sometimes occurring without severe symptoms.
Can low calcium intake increase kidney stone risk?
Adequate dietary calcium binds oxalates in the intestine, reducing their absorption. Too little calcium leaves more available to reach the kidneys and form crystals.
Why is urine pH important for kidney stone prevention?
Urine acidity affects which substances crystallise. Highly acidic urine promotes uric acid formation, while excessive alkalinity can favour calcium phosphate crystallisation.
