Whether it is the treatment of acute pyelonephritis or chronic pyelonephritis, first of all, personal hygiene should be emphasized, physical fitness should be enhanced, water intake should be increased, and urination should be frequent. In addition, for patients with acute pyelonephritis, the main treatment is the use of sensitive antibiotics, which can be either semi-synthetic penicillin or cephalosporins, and fluoroquinolone antibiotics can also be used. For chronic pyelonephritis, if the patient has urinary anatomical or functional abnormalities, such as the presence of urinary stones or urinary obstruction, active surgical treatment can be considered to relieve the obstruction. Furthermore, patients with chronic pyelonephritis who also have hypertension and edema can appropriately use antihypertensive drugs and diuretics to control blood pressure and edema, which can play a role in protecting kidney function. (The use of medications should be conducted under the guidance of a doctor.)
