Acute pyelonephritis is one of the most common indications for antepartum h
ospitalisation. When acute pyelonephritis is diagnosed, conventional treatm
ent includes intravenous fluid and parenteral antibacterial administration.
There are limited data by which to assess the superiority of one antibacte
rial regimen over the other in terms of efficacy, patient acceptance and sa
fety for the developing fetus. There is a small body of evidence to support
the ambulatory treatment of pregnant women with pyelonephritis in the firs
t and early second trimesters.
