Kidney stones, also known as calculi or nephrolithiasis, are abnormal, hard, crystalline materials formed inside the Kidneys. The size of kidney stones may be very small in the form of sand grains, the size of a pea, or even larger than a marble.
The four common types of stones found in Kidneys are calcium stones, struvite stones, cystine stones, or uric acid stones.
The symptom of kidney stones largely depends on the size of stone, its location, and associated factors. Some stones are harmless (mostly silent without symptoms), while others cause sudden excruciating, cramping pain in the lower back and/or in the side, abdomen, or groin. Pain often starts suddenly and will be intense. In case kidney stones, the pain usually starts at the mid back and often radiates to the groin, while for men, it may radiate to testicle and scrotum as well.
Other symptoms associated with pain are sweating, nausea and vomiting. At times there may be blood present in the urine, as the stone can irritate the ureter or kidney. Any associated infection in the urinary tract, apart from stones, may result in fever and chills. Kidney stones may also lead to other symptoms such as difficulty in urination, penile or testicular pain and urinary urgency.
Kidney stones are formed due to imbalance of water, minerals, salts and other substances in the urine. The cause of imbalance determines the type of kidney stone that you have.
One of the main reasons for formation of kidney stones is inadequate water intake. Dehydration or loss of fluid from the body is the main risk factor for kidney stones.
Urinary tract infection can also lead to formation of kidney stones. However, the stones so formed (called struvite stones) can grow quite large and block kidney, ureter or bladder.
Certain medical conditions such as gout patients, people with parathyroid disorders, those on chemotherapy, people with intestinal diseases, or those after surgery, are at higher risk of developing uric acid stones.
Kidney stones can also be caused due to hereditary factors. If one or both of your parents had kidney stones, you are at higher risk of developing the same.
