急性增生性肾小球肾炎(Acute proliferative glomerulonephritis)是在肾小球(肾小球肾炎)、或肾小管中所产生的病症。它常见于细菌感染的并发症中，通常是由链球菌(脓疱病)所造成的皮肤感染，也可以是链球菌性咽炎所造成的感染，亦被称为"感染后肾小球肾炎"(postinfectious glomerulonephritis)或链球菌感染后肾小球肾炎(poststreptococcal glomerulonephritis)。 它可以是"未来所出现的白蛋白尿"之危险因素。 在成年人中，肾脏问题发生时"急性增生性肾小球肾炎"所感染的症状和病征仍然会随时出现，也会使用这些医学术语"相关感染的肾小球肾炎"(infection-related glomerulonephritis)或"细菌相关感染的肾小球肾炎"(bacterial infection-related glomerulonephritis)表示之。

Acute proliferative glomerulonephritis is a disorder of the glomeruli (glomerulonephritis), or small blood vessels in the kidneys. It is a common complication of bacterial infections, typically skin infection by Streptococcus bacteria types 12,4 and 1 (impetigo) but also after streptococcal pharyngitis, for which it is also known as postinfectious or poststreptococcal glomerulonephritis. It can be a risk factor for future albuminuria. In adults, the signs and symptoms of infection may still be present at the time when the kidney problems develop, and the terms infection-related glomerulonephritis or bacterial infection-related glomerulonephritis are also used. Acute glomerulonephritis resulted in 19,000 deaths in 2013 down from 24,000 deaths in 1990.
