Kidney Stones: Symptoms and Diagnosis

, organic compounds and other substances present in the urine that form "pebbles" of varying sizes. When a kidney stone begins to form, there are two possible evolutions:

1. The stone continues to grow, due to the progressive accumulation of precipitated salts, until it completely occupies the cavity it is in, almost as if it were a mold. In these cases, the affected kidney can completely lose its function.
2. In the second case, which is the most common one, the precipitated material is instead dragged by the urinary stream and expelled. The risk, in these cases, is that the stone, flowing out with the urine, creates lesions on the walls of the urinary tract and then the situation becomes complicated by determining the appearance of blood in the urine or, if the stone reaches a smaller point than the "ureter, can cause it to become blocked causing renal colic or even a blockage of urination.
