Poor renal function with edema is common in acute and chronic glomerulonephritis, nephrotic syndrome, acute and chronic renal failure, renal tumors and other renal diseases, and the commonly used diuretic methods mainly include drug therapy, hemodialysis or peritoneal dialysis and surgical treatment. 1. Drug treatment: If the kidney function is impaired due to acute and chronic glomerulonephritis, nephrotic syndrome, chronic renal failure and other renal diseases, which cause edema, diuretics such as hydrochlorothiazide, furosemide, spironolactone and so on can be taken as prescribed by the doctor. 2. Hemodialysis or peritoneal dialysis: If it is seen in acute and chronic renal failure and other diseases, when renal function is seriously impaired, hemodialysis or peritoneal dialysis can also be prescribed to improve edema. 3. Renal tumor: Usually, patients with renal tumor can be treated according to their own conditions and cooperate with doctors to perform surgery such as tumor resection, and if necessary, radiation therapy, targeted therapy, chemotherapy and other ways to improve edema and other symptoms. Some patients can also be treated with diuretics such as hydrochlorothiazide, furosemide and spironolactone. It is recommended that patients with poor renal function and edema should consult a doctor in time, complete the relevant examinations, and follow the doctor’s instructions to standardize the treatment after clarifying the cause of the disease.
