The kidneys are essential organs for our body since they perform functions beyond the urine production that we excrete daily. They are small organs (about 18 cm long) that regulate the body’s blood pressure, produce red blood cells, purify the blood and regulate the body’s fluids to preserve or excrete the products of elimination: glucose, sodium, potassium and other substances to maintain the stability of the organism.
The kidneys are part of the urinary system along with the ureters, bladder, and urethra. The urine that forms in these organs is transported to the renal pelvis, passes to the ureters and bladder, where it is eliminated through the voluntary and conscious action of urination. This urine is composed of urea, sodium chloride, sulfates, phosphates, creatinine, ammonium salts, hippuric acid, uric acid and, when wastes are not properly disposed of, or there is not enough fluid in the blood, they accumulate and attach to the kidneys.
Those clusters are kidney stones, known colloquially as kidney stones: a solid mass composed of tiny crystals of calcium oxalate.
Follow these simple tips to keep your kidneys healthy and, in general, to have good health. If you begin to feel the typical kidney stones pains (sharp pain in the back or lower abdomen, presence of blood in the urine, pain when urinating, inability to urinate or just excreting a small amount) go immediately to the specialist.
