Most small kidney stones pass on their own with fluids and pain relief. Larger stones, and stones that block the flow of urine, are a urological emergency. This guide covers what kidney stones are, the stone types and why the type matters, how they are diagnosed, the remedies homeopaths commonly consider, and the symptoms that mean you should go to hospital today.

What are kidney stones?

A kidney stone is a hard mass formed when minerals and salts that are normally dissolved in urine crystallise and stick together. Your kidneys filter waste from the blood and pass it out as urine; when urine becomes too concentrated — usually because you are not drinking enough — those minerals have nothing to stay dissolved in.

Stones range from a grain of sand to a mass filling the whole collecting system. The name changes with location: nephrolithiasis when the stone is in the kidney, ureterolithiasis when it is in the ureter, and urolithiasis as the general term for stones anywhere in the urinary tract. Men are affected roughly twice as often as women, and once you have had one stone your chance of forming another within ten years is high — which is why prevention matters as much as treatment.

The four stone types — and why the type changes the advice

Prevention advice is different for each type, so if you pass a stone, catch it and send it for analysis. It is the single most useful thing you can do to avoid the next one.

Calcium stones About 80% of all stones, usually calcium oxalate. Formed when urine is concentrated or oxalate intake is high. Counter-intuitively, cutting dietary calcium makes these worse — calcium in food binds oxalate in the gut so less reaches the kidney.
Uric acid stones Form in persistently acidic urine. Linked to high intake of red meat, organ meat and shellfish, to gout, to dehydration and to chronic diarrhoea. These are the one type that can sometimes be dissolved medically.
Struvite stones Form in response to urinary tract infection with certain bacteria. They grow quickly and can become very large “staghorn” stones. These need urological treatment — the infection and the stone feed each other.
Cystine stones Rare, caused by an inherited disorder (cystinuria) that leaks an amino acid into urine. Usually start in childhood or early adulthood and recur throughout life.

What causes kidney stones

  • Dehydration — the single biggest factor, and the reason stones are more common in hot, dry regions and in people who work outdoors
  • Family history — stones run strongly in families
  • A diet high in salt (salt drives calcium into the urine), animal protein or oxalate-rich foods
  • Low fluid intake, or heavy fluid loss through sweat without replacement
  • Obesity and a high BMI
  • Repeated urinary tract infections
  • Medical conditions: hyperparathyroidism, renal tubular acidosis, Crohn’s disease, chronic diarrhoea, medullary sponge kidney, Dent’s disease, gout
  • Certain long-term medicines, including some diuretics, calcium-based antacids and a few antiretrovirals
  • Previous bariatric or intestinal surgery

Symptoms of kidney stones

kidney Stone DisordersA stone sitting quietly in the kidney can cause nothing at all. Pain begins when it moves into the ureter and blocks urine flow. Typical features are:

  • Renal colic — severe pain in the flank or side that comes in waves, often described as the worst pain a person has experienced. It classically radiates from the loin down to the groin as the stone travels
  • Restlessness — people with colic pace and cannot find a comfortable position (unlike, say, peritonitis, where people lie still)
  • Blood in the urine, which may be visible pink or brown, or found only on testing
  • Burning on passing urine
  • Passing small amounts of urine frequently, with a persistent urge
  • Cloudy or foul-smelling urine
  • Nausea and vomiting
  • Fever and chills — this combination with colic is an emergency (see below)

The location of the pain shifts as the stone moves down the ureter, and the severity depends on the degree of obstruction rather than the size of the stone: a small stone stuck in a narrow point can hurt far more than a large one sitting still.

How kidney stones are diagnosed

  • Non-contrast CT of the kidneys, ureters and bladder (CT KUB) — the most accurate test; shows size, position and density
  • Ultrasound — first choice in pregnancy and in children, and useful for showing swelling of the kidney (hydronephrosis)
  • Urine examination — for blood, crystals and infection
  • Blood tests — kidney function, calcium and uric acid
  • Stone analysis after passing or removal, and in recurrent stone-formers a 24-hour urine collection to find the metabolic cause

How homeopathy is used in kidney stones

Homeopaths prescribe on the total picture: the character and direction of the pain, what makes it better or worse, the appearance of the urine, associated nausea, and your constitution and history. Remedies are given to help with the pain, spasm and urinary irritation of colic, and — between episodes — as constitutional treatment in people who form stones repeatedly.

Be clear about the limits. There is no reliable evidence that homeopathic remedies dissolve or break up stones. Whether a stone passes depends mainly on its size and position: stones under about 5 mm usually pass with fluids and analgesia, while stones above about 10 mm, or any stone causing obstruction with infection, need urological treatment such as shock-wave lithotripsy (ESWL), ureteroscopy or PCNL. Delaying that treatment while waiting for a stone to “dissolve” risks permanent kidney damage. Use homeopathy for symptom support and for the long game of preventing the next stone — not as a substitute for imaging and urological care.

Remedies homeopaths commonly consider

For information only; selection, potency and repetition must be decided by a qualified homeopath.

Berberis vulgaris The most cited remedy in renal colic; classically for radiating, shooting pain in the left kidney travelling down to the bladder and thigh, worse for movement and jarring.
Lycopodium clavatum Considered for right-sided renal pain, red sandy sediment in the urine, and pain that eases after passing urine; often accompanied by bloating and gas.
Cantharis Used where intense burning before, during and after urination dominates, with constant unbearable urging and only drops passed.
Sarsaparilla officinalis Classically for severe burning at the end of urination, and for urine that can only be passed standing.
Hydrangea arborescens Traditionally called the “stone breaker” in homeopathic literature; used where white gravelly deposit is seen in the urine.
Ocimum canum Considered for right-sided colic with vomiting, restlessness and a strong smell to the urine.

How to prevent kidney stones coming back

  • Drink enough to pass about 2.5 litres of urine a day. The practical test is colour: pale straw is right, dark yellow is not. Drink more in summer and if you work outdoors or exercise heavily.
  • Cut salt, not calcium. Reducing salt lowers the calcium in your urine. Keep normal dietary calcium from milk, curd and paneer — but discuss calcium supplements with your doctor, as those behave differently.
  • Moderate oxalate-rich foods if you form calcium oxalate stones: spinach, beetroot, nuts, chocolate, strong tea and soy. You do not need to eliminate them — eat them with a calcium-containing food instead.
  • Limit animal protein — red meat, organ meat and shellfish raise uric acid and urinary calcium.
  • Add citrus. Lemon and lime juice raise urinary citrate, which inhibits stone formation. A little lemon in your water each day is a genuinely useful habit.
  • Cut sugary drinks, especially colas.
  • Keep a healthy weight and include fresh fruits and vegetables in your diet.
  • Treat urinary infections promptly rather than letting them recur.

When to go to hospital

Go to an emergency department the same day if you have:

  • Fever or chills with flank pain — an infected, obstructed kidney can become life-threatening within hours
  • Pain so severe that you cannot control it with the painkillers you have
  • Persistent vomiting and inability to keep fluids down
  • Passing little or no urine at all
  • Visible blood in the urine with clots
  • A single functioning kidney, a transplanted kidney, or known kidney disease, with any colic at all
  • Pregnancy with flank pain

Frequently asked questions

Can homeopathy dissolve a kidney stone?

There is no reliable evidence that it does. Homeopathic remedies are used for the pain, spasm and urinary symptoms and as constitutional treatment to reduce recurrence. Whether a stone passes is determined mainly by its size and position, which needs imaging to establish.

How long does a stone take to pass?

Small stones (under about 4–5 mm) often pass within one to three weeks with good hydration. If a stone has not passed in four to six weeks, or symptoms worsen at any point, it needs review — a persistently obstructed kidney can lose function.

Should I strain my urine?

Yes, if your doctor has advised you to try passing the stone. Use a fine strainer or a piece of muslin, and send whatever you catch for analysis. Knowing the stone type transforms the prevention advice.

Does drinking beer help pass stones?

No. Alcohol dehydrates you and raises uric acid, both of which make stones more likely. Any fluid benefit is more than offset. Plain water is what works.

I have had one stone. Will I get another?

Without prevention, recurrence is common — roughly half of people form another stone within five to ten years. Consistent hydration, salt reduction and treating the underlying metabolic cause bring that risk down substantially.

Consulting a homeopath
