Acute nephritis is a self-limiting disease, and most patients can fully recover, so the vast majority of patients generally start to show improvement in routine urine tests three to four weeks after onset, with normal kidney function and resolution of edema, resulting in few, if any, sequelae. Of course, a small number of patients may experience prolonged unhealed conditions that can progress to chronic nephritis. These patients may then develop complications, including hypertension and renal anemia, which are long-term potential issues. However, the vast majority of patients with acute nephritis do not experience complications or sequelae.
