Renal calculi: Kidney stones. A common cause of blood in the urine and pain in the abdomen, flank, or groin. Occurs in 1 in 20 people at some time in their life.

Nephrolithiasis is the medical term for kidney stones. ... Symptoms of a kidney stone include flank pain (the pain can be quite severe) and blood in the urine (hematuria). ... Most kidney stones will pass through the ureter to the bladder on their own with time. Kidney stones are small, hard deposits that can form in a part of the kidney called the renal pelvis. Kidney stones that enter a ureterare sometimes referred to as ureteral stones. The ureters are the tubes that carry urine from the kidneys to the bladder. Many of these stones are so small that they are able to travel to the bladder in just a few days or weeks without any treatment, and then exit the body in your urine. So if the stones are smaller, it's often enough to take painkillers, drink plenty of fluids and simply wait for the kidney stones to pass through. Muscle-relaxing medications can be used to help pass medium-sized stones. Larger stones may get stuck as they exit the renal pelvis or take longer to move through the ureter, causing severe pain and other symptoms. Then they usually need to be broken up by sound waves or surgically removed. The most suitable treatment will depend on the size, the type and the position of the stones in the kidney or the urinary tract.
