It is determined by urine - in relation to its quantity, degree of liquid, color and impurities, by the degree of thirst, by the degree of passion for copulation, by the condition of the back and the presence of pain in it, by the condition of the legs, by the nature of the pain itself, as well as by palpation and on what treatment measures are appropriate or not appropriate.
Kidney diseases are sometimes accompanied by scanty urine output and differ from similar liver diseases in that passion does not decrease completely. Anyone who emits urine with a lot of bubbles on top has a kidney disease. It’s the same if a person’s urine is mature, with sediment in the form of meat slop, with fibrous sediment and with sediment like lenticular vetch, because maturation occurs in the kidneys. However, if the maturity is very high and there is an admixture of other things, it can be assumed that the disease nests in the bladder, and if the maturity is less, then in the kidneys. When you do not see maturity, then consider that the beginning of the disease is in the liver, for the maturity of urine is determined only by the condition of the upper organs; If they were not healthy, there would be no maturity; if there were no damage in them, there would be no lack of maturity.
