What are kidney stones?
Kidney stones, as the name itself suggests, are stones that form in the kidneys and can be as tiny as a speck of dust, or as big as the size of a tennis ball. Apart from the kidneys, the stones can also form anywhere along the urinary tract which includes the ureter, bladder, and urethra.
After your body absorbs the nutrition it needs, the remaining waste products travel through the bloodstream to the kidneys. The waste products get removed from your body through urine. When there is too much of waste and too less liquid in the urine, crystals begin to form which stick together and form solid masses or kidney stones.
The common symptoms of kidney stones include:
- Foul smelling urine
- Discoloured urine: pink, red, brown urine or blood in the urine
- Frequent and urgent need to urinate
- Fever and chills
- Nausea and vomiting
- Shifting pain in the lower abdomen and groin
- Varying intensity of pain that comes and goes
Although the exact causes leading to the formation of the stones have not been established yet, a number of factors have been identified which increases the risk of kidney stones.
Risk factors for kidney stones include:
- Inadequate consumption of water
- A family history of kidney stones
- Being bed-bound due to illness
- Sedentary lifestyle
- Suffering from frequent urinary and kidney infections
- Eating a high-protein diet and low-fiber diet
- Consumption of excessive sodium (salt)
- Active medical conditions such as Crohn's disease, gout, renal tubular acidosis, hyperparathyroidism, medullary sponge kidney, type 2 diabetes, and Dent's disease
- Excessive consumption of supplements such as calcium and vitamin C
What are the types of kidney stones?
There are four main types of kidney stones:
- Calcium Stones: Calcium stones are the most common form of kidney stones. They are formed when there is too much calcium in the urine. They may form due to an overactive parathyroid gland, an inherited condition called hypercalciuria, kidney disease, some cancers, or a condition called sarcoidosis.
- Struvite Stones: These are horn-shaped and can grow quite large. They are usually caused by urinary tract infection.
- Uric Acid Stones: Uric acid stones are softer than other types of kidney stones. They may occur due to a high-protein low-fibre diet. Patients suffering from gout are found to be at a higher risk to get uric acid stones.
- Cystine Stones: They are caused by a rare hereditary disorder called cystinuria. Cystine stones are larger than other forms of kidney stones and tend to recur.
In about 85% of the cases, small kidney stones (<5 mm) pass out in the urine without medical intervention. Stones bigger than 5 mm may require medical intervention. Stones as small as 2 mm have been known to cause discomforting symptoms.
What kind of a doctor should I consult for kidney stone removal?
If you experience any of the aforementioned symptoms of kidney stones, you should immediately consult your family doctor or a general physician, who in turn may refer you to a urologist if a kidney stone is suspected.
How are kidney stones diagnosed?
After getting to know your symptoms, medical history and after a complete examination, the urologist will suggest tests to confirm the diagnosis of kidney stones. The tests may include:
- A computerized tomography (CT) scan – where a computerized low-intensity X-Ray images are taken from different angles and analyzed.
- X-ray - which uses a low dose of electromagnetic radiation to accurately create images of the internal structures of your body. Radiolucent stones such as Cystine or uric acid stones may not be identified with this test.
- Ultrasound scan: Images of the internal structures of your body are recreated using high-frequency sound waves.
- Intravenous urogram (IVU) or intravenous pyelogram (IVP): In this procedure, a radio-opaque dye is injected through a vein in your arm. This dye highlights the presence of the stones on an X-ray. The dye later passes out of your body in the urine. It is advised that you inform the doctor about all your current medicines and allergies before undergoing this procedure. Before administering the dye though, your urologist will make sure that you are not allergic to it.
What are the kidney stone removal procedures?
The following treatments and procedures are available to manage kidney stones:
- Diet: Your doctor/dietician may prescribe you with a modified diet.
- Medications: Your doctor may prescribe medicines which can dissolve certain types of kidney stones. (ex. kidney stones formed of calcium or uric acid can be treated with medicines.)
Other medicines are also prescribed to relieve the symptoms of kidney stones which include:
- pain medicines
- muscles relaxants which assist the stones to pass through
- antibiotics to manage any infection
- Other medications to manage the underlying disease that is causing the kidney stone
If a change of diet and medicines do not work, the doctor may ask you to undergo any of the following kidney stone procedures based on the size and type of stone you have:

Endoscopy is a minimally invasive procedure in which a long flexible tube with an attached camera is inserted through an incision or an opening in the body so that the doctor can view an internal organ or a piece of tissue minutely.
Lithotripsy can be performed to break stones in the various organs of the body such as kidney, gallbladder, liver, etc.
A urinary tract infection occurs when microbes gets into any part of the urinary tract, i.e. the kidneys, ureters, bladder, or urethra. In this article learn about the causes, symptoms and treatment of UTIs.
