Kidney stones (also called renal calculi, nephrolithiasis or urolithiasis) are hard deposits made of minerals and salts that form inside your kidneys.
Diet, excess body weight, some medical conditions, certain supplements and medications are among the many causes of kidney stones. Kidney stones can affect any part of your urinary tract – from your kidneys to your bladder. Often, stones form when the urine becomes concentrated, allowing minerals to crystallize and stick together.
Symptoms
A kidney stone usually will not cause symptoms until it moves around within your kidney or passes into your ureters – the tubes connecting the kidneys and the bladder. If it becomes lodged in the ureters, it may block the flow of urine and cause the kidney to swell and the ureter to spasm, which can be very painful.
- Severe, sharp pain in the side and back, below the ribs
- Pain that radiates to the lower abdomen and groin
- Pain that comes in waves and fluctuates in intensity
- Pain or burning sensation while urinating
Other signs and symptoms may include:
- Pink, red or brown urine
- Cloudy or foul-smelling urine
- A persistent need to urinate, urinating more often than usual or urinating in small amounts
- Nausea and vomiting
- Fever and chills if an infection is present
Causes
- Kidney stones often have no definite, single cause, although several factors may increase your risk.
- Kidney stones form when your urine contains more crystal-forming substances – such as calcium, oxalate and uric acid – than the fluid in your urine can dilute. At the sametime, your urine may lack substances that prevent crystals from sticking together, creating an ideal environment for kidney stones to form.
Types of kidney stones
1. Calcium stones. Most kidney stones are calcium stones, usually in the form of calcium oxalate. Oxalate is a substance made daily by your liver or absorbed from your diet. Certain fruits and vegetables, as well as nuts and chocolate, have high oxalate content.
Dietary factors, high doses of vitamin D, intestinal bypass surgery and several metabolic disorders can increase the concentration of calcium or oxalate in urine. Calcium stones may also occur in the form of calcium phosphate. This type of stone is more common in metabolic conditions, such as renal tubular acidosis. It may also be associated with certain medications used to treat migraines or seizures, such as topiramate (Topamax, Trokendi XR, Qudexy XR).
2. Struvite stones. Struvite stones form in response to a urinary tract infection. These stones can grow quickly and become quite large, sometimes with few symptoms or little warning.
3. Uric acid stones. Uric acid stones can form in people who lose too much fluid because of chronic diarrhea or malabsorption, those who eat a high-protein diet, and those with diabetes or metabolic syndrome. Certain genetic factors also may increase your risk of uric acid stones.
4. Cystine stones. These stones form in people with a hereditary disorder called cystinuria that causes the kidneys to excrete too much of a specific amino acid.
Risk factors
Factors that increase your risk of developing kidney stones include:
- Family or personal history. If someone in your family has had kidney stones, you’re more likely to develop stones, too. If you’ve already had one or more kidney stones, you’re at increased risk of developing another.
- Dehydration. Not drinking enough water each day can increase your risk of kidney stones. People who live in warm, dry climates and those who sweat a lot may be at higher risk than others.
- Certain diets. Eating a diet that’s high in protein, sodium (salt) and sugar may increase your risk of some types of kidney stones. This is especially true with a high-sodium diet. Too much salt in your diet increases the amount of calcium your kidneys must filter and significantly increases your risk of kidney stones.
- Obesity. High body mass index (BMI), large waist size and weight gain have been linked to an increased risk of kidney stones.
- Digestive diseases and surgery. Gastric bypass surgery, inflammatory bowel disease or chronic diarrhea can cause changes in the digestive process that affect your absorption of calcium and water, increasing the amounts of stone-forming substances in your urine.
- Other medical conditions such as renal tubular acidosis, cystinuria, hyperparathyroidism and repeated urinary tract infections also can increase your risk of kidney stones.
- Certain supplements and medications, such as vitamin C, dietary supplements, laxatives (when used excessively), calcium-based antacids, and certain medications used to treat migraines or depression, can increase your risk of kidney stones.
Homoeopathic Treatment
- Medorrhinum: Renal (STONE) colic; with cold fingers; while coughing; with the craving of ice.
- Sarsaparilla: Passage of gravel or small calculi; RENAL colic; STONE in bladder; bloody urine. Urine: bright and clear but irritating; scanty, slimy, flaky, sandy, copious, passed without sensation; deposits white sand
- Nux-v: RENAL colic is caused by a STONE in the ureter, which by its irritation causes a spasmodic clutching of the circular fibers of that canal; the proper medicine relaxes these fibers and the pressure from behind forces the calculi out at once.
- Cantharis: Constant and intolerable urging to urinate before, during and after urination. Burning, scalding urine, with cutting, intolerable urging, and fearful tenesmus or dribbling strangury. Urine is passed drop by drop. Intolerable urging with tenesmus. Urine scalds the passage. Jelly-like shreddy urine.
- Berberis vulgaris: Painful cuttings left side bladder into the urethra, comes from the left kidney (continued) along the course of the ureter. Blood-red urine, speedily becomes turbid, deposits thick, mealy, bright red sediment, slowly becoming clear, but always retaining its blood.
