Kidney stones also called renal are hard deposits made of minerals and salts that form inside your kidneys.
Diet, excess body weight, some medical conditions, and certain supplements 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.
Passing kidney stones can be quite painful, but the stones usually cause no permanent damage if they’re recognized in an early stage. Depending on your situation, you may need nothing more than to take pain medication and drink lots of water to pass a kidney stone. In other instances for example, if stones become lodged in the urinary tract, are associated with a urinary infection or cause complications then surgery may be needed.
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. At that point, you may experience these signs and symptoms:
- 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
- Progression Trajectory.
The sooner you know you have kidney disease, the sooner you can make changes to protect your kidneys.
