Generally speaking, regardless of the disease, the condition is often stable when patients are discharged from the hospital, including the management of acute nephritis. The length of hospital stay for patients with acute nephritis depends on the individual condition of the patient. If the condition of acute nephritis is mild and the patient does not have obvious symptoms, such as mild proteinuria and hematuria, such patients may be hospitalized for about a week. After assessing the condition and predicting gradual improvement, the patient can be discharged. However, if acute nephritis causes some serious complications and the patient's condition is unstable, such as leading to congestive heart failure, some patients may also develop acute renal failure and severe consequences like lung infections. Before these complications are controlled and stabilized, the patient cannot be discharged, and the hospital stay may even exceed one month.
