Renal failure. Signs, current. In an initial stage an acute renal failure on the foreground the signs caused by a shock (painful, anaphylactic or infectious toxic), act as a hemolysis, an acute poisoning, an infectious disease, but already in the first day falling a diuresis (less than 500 ml in day) is found out. In plasma alongside with rising of levels of a creatinine, urea, a filtrate nitrogen, Zinci sulfases, Natrii phosphases, a magnesium, a potassium levels of sodium, chlorine and a calcium decrease. Set of humoral disturbances causes accrueing signs of an acute uremia. The adynamia, loss of appetite, a nausea, a vomiting, a diarrhea are characteristic. In process of increase of an azotemia, an acidosis, an overhydratation and electrolytic disturbances there are muscular twitchings, a sleepiness, retardation, the dyspnea because of an acidosis and a fluid lungs which early stage is defined by roentgenography amplifies.

The tachycardia, expansion of borders of heart, deaf tones, systolic hum on an apex, sometimes a pericardial rub are characteristic. At a part of patients - an arterial hypertensia. Frustration of a rhythm are quite often bound to a hyperpotassemia: it is especially dangerous and can cause sudden mors. Abdominal pains, augmentation of a liver - frequent signs of an acute uremia. The mors at an acute renal failure comes from a uremic coma, disturbances of a hemodynamic and a sepsis more often. At an acute renal failure the hypoisosthenuria is from the very beginning found out. The maintenance of fiber in urine and character of a urinary deposit depend on the reason of an acute renal failure. The augmentation of a diuresis more than 500 ml in day means the period of restoration of a diuresis. Clinical improvement becomes obvious, even after offensive of a polyuria, not at once, and gradually, in process of depression of a level of an azotemia and restoration of a homeostasis. By time of normalization of the maintenance of a filtrate nitrogen in a blood the homeostasis basically is restored - the period of convalescence. During this period renal processes are restored. It lasts about one year and more. However at a part of patients depression of a glomerular filtration and concentration ability of kidneys remains, and at the some people the renal failure accepts chronic current, the important role thus is played with the joined pyelonephritis.
