Should I Be Screened?
Kidney stones are hard deposits made of minerals and salts that form inside your kidneys.
Kidney stones have many causes and 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.
A kidney stone may not cause symptoms until it moves around within your kidney or passes into your ureter, the tube connecting the kidney and bladder. At that point, you may experience these signs and symptoms:
- Severe 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 on urination
- Pink, red or brown urine
- Cloudy or foul-smelling urine
- Nausea and vomiting
- Persistent need to urinate
- Urinating more often than usual
- Fever and chills if an infection is present
- Urinating small amounts
The leading cause of kidney stones is a lack of water in the body.
Stones are more commonly found in individuals who drink less than the recommended eight to ten glasses of water a day.
When there is not enough water to dilute the uric acid, a component of urine, the urine becomes more acidic.
An excessively acidic environment in urine can lead to the formation of kidney stones.
Medical conditions such as Crohn’s disease, urinary tract infections, renal tubular acidosis, hyperparathyroidism, medullary sponge kidney, and Dent’s disease increase the risk of kidney stones.
