Kidney stones can develop when there is an excessive buildup of calcium, uric acid, oxalate, or cystine in the body. The primary type of kidney stone is composed of calcium oxalate. Cystine stones are uncommon and typically affect individuals with a genetic disorder that results in cystine leakage from the kidneys into the urine. On the other hand, struvite stones, another type of kidney stone, are associated with urinary tract infections and are more prevalent in women. Most kidney stones are small, similar to a grain of sand, and can pass through the urine without causing any noticeable symptoms. However, if the stones continue to grow and reach the size of a pebble or even a golf ball, they become too large to pass through the urinary tract, leading to the onset of pain and other associated symptoms.
Sharp Pain
Kidney stones often cause sharp and intense pain, known as renal colic. The location of the stone in the body determines the specific area where the pain is felt most intensely. Typically, individuals experience pain on one or both sides of the lower back. However, if the stone is situated lower down, the pain can become more concentrated in the groin area. In certain cases, the pain may originate in the back and radiate to the stomach, resulting in severe spasms or persistent throbbing sensations.
Painful Urination: A Common Symptom of Kidney Stones
One of the most noticeable symptoms of kidney stones is excruciating pain during urination. When a kidney stone gets stuck in the urinary tract, it obstructs the normal flow of urine through the ureter. As a result, the stone rubs against the delicate lining of the kidney or other parts of the urinary tract, causing intense discomfort and pain. The severity of pain while urinating is typically highest when the stone becomes lodged at the point where urine enters the bladder.
