Whether acute nephritis requires hospitalization depends on the patient’s condition, such as the severity of clinical symptoms, whether kidney function is impaired, whether there are cardiac and cerebral complications, etc. If the condition is mild, hospitalization is not necessary, but if the clinical symptoms are severe or accompanied by severe renal impairment, hospitalization is generally required. Acute nephritis is a kidney disease caused by pathogenic bacterial infection, resulting in hematuria, proteinuria, swelling, hypertension and other symptoms, and severe renal insufficiency, as well as water-electrolyte and acid-base balance disorders. If there is only mild hematuria, proteinuria, normal or mildly elevated blood pressure and normal or mildly impaired renal function, hospitalization is not necessary. In the acute stage, patients should rest in bed and wait for the disappearance of hematuria, the subsidence of edema and the return of blood pressure to normal. Diet should be low-salt, low-fat, high-quality protein diet. If the patient has serious renal impairment, hospitalization is generally recommended for standardized treatment, and blood purification treatment is also needed in serious cases. Whether acute nephritis needs hospitalization or not is related to the condition, it is recommended that patients with acute nephritis should go to the hospital in time to see the physician for assessment to clarify whether hospitalization is needed and cooperate with the physician for active treatment.
