Acute renal failure have oliguria?

Apart from acute renal failure oliguria no urine, there are also non-oliguric type, non-oliguric patients with an average daily urine 1000 ml. In recent years a type of non-oliguric than as high as 30% to 60%, due to increased incidence of ① to raise awareness of the disease; ② increase in the use of aminoglycoside antibiotics; ③ early treatment on rational drug use, such as: Furosemide, dopamine and mannitol, and expand blood volume increased renal perfusion, and because of increased urine volume of urine scouring effect. Instead of oliguria of urine does not reduce the following three possible reasons: ① acute renal tubular necrosis unit to absorb the damage is not one, a small part of the glomerular filtration rate is still relatively complete, and the tubular reabsorption function significantly decreased, and renal failure metabolites retention, infiltration Of the diuretic effect; ② glomerular filtration injury in the light tubular reabsorption dysfunction, which can not be good conditioning tubular urine, produced more urine; ③ remote impaired renal function, the permeability of regulation deficiencies exist, not between the medulla Appropriate form of increased osmotic pressure gradient, concentrated urine dysfunction, urine more. Non-oliguric acute renal failure glomerular filtration rate is still substantially different levels of decline, and nitrogen-containing material in the reserves far greater than the removal of the kidney, blood urea nitrogen urea and creatinine in a sharp increase , Niaobi Chong low and fixed, a protein in the urine, such as the type. Because such patients can be discharged within the urinary potassium, phosphate and chlorine, is complicated by hyperkalemia, acid poisoning, hypocalcemia less common, the chance of less severe diseases, fewer complications, but the mortality rate remains as high as 26 % In the treatment of any link can not be ignored.
