This fluid retention is usually mild and is referred to as “physiological” pyelonephritis in pregnancy. Urine stagnation favors urinary tract infections and can progress to severe pyelonephritis; Renal blood flow and glomerular filtration rate in pregnant women are increased by approximately 40% of normal. These flows increase quite early, as early as the first months of pregnancy. This increase in glomerular filtration rate increases the excretion of waste products. Serum creatinine levels decrease by about 35 to 44% of the normal value. Decrease blood albumin concentration, decrease blood urea and decrease plasma osmolality; The amount of water increases about 6-9 liters, of which mainly water is in the extracellular compartment, about 4-6 liters. During pregnancy the plasma volume almost doubles and edema is normal.
