Nephrogenic edema refers to edema caused by renal diseases, such as acute and chronic glomerulonephritis, nephrotic syndrome and renal failure, which can cause edema and are described separately below. The pathogenesis of edema caused by acute and chronic glomerulonephritis is the imbalance between the glomerular filtration rate and the tubular reabsorption capacity, causing edema, mainly in the eyelids and face. Second, edema caused by nephrotic syndrome, the pathogenesis is hypoproteinemia, which refers to the patient’s increased urine protein, causing a decrease in albumin in the blood, and hypoproteinemia, resulting in a decrease in colloid osmotic pressure and triggering edema. Treatment of nephritis and nephrotic syndrome is mainly hormonal and/or combined with cytotoxic drugs. Diuretics such as furosemide, spironolactone and hydrochlorothiazide can be used to diureticize and reduce swelling. Third, edema caused by renal failure, the pathogenesis is serious damage to renal function, glomerular function has been lost, patients appear oliguria or anuria, and water and sodium retention, causing edema, treatment is mainly the application of diuretics such as furosemide, torasemide to diuretic swelling, improve renal function and other treatment.
