Why kidney stones

Kidney stones refer to the abnormal accumulation of crystalline substances in the kidneys. The composition of stones is very complex, and calcium oxalate stones are the most common. The process of stone formation is that the concentration of crystalline substances in the urine increases or the solubility decreases to form a supersaturated state. The precipitated crystals will grow and accumulate locally, and finally form stones. There are many factors that affect stones. Gender, age, race, eating habits, occupation and stone formation are all related, and the body's metabolic abnormalities. For example, increased cortisol, hyperparathyroidism, long-term bed rest, nutritional deficiencies, urinary tract obstruction, infection, foreign bodies, and drug use are all common causes of stones.

Symptoms of kidney stones

Symptoms of kidney stones: if the location of kidney stones is stable, it rarely causes obvious pain. If there is paroxysmal pain or persistent pain in the waist and abdomen, it is mostly because the location of the kidney stones has moved, or the kidney stones have entered the ureteral junction or the ureter, causing renal colic. It suddenly radiates to the lower abdomen, groin or inner thigh, often accompanied by urinary tract obstruction. Related symptoms include hematuria, decreased urine volume or gastrointestinal symptoms. Hematuria is an important manifestation of kidney stones, which occurs because stones migrate and damage urothelial cells. Diagnosis generally requires urine routine, and CT examination can confirm the diagnosis.
