Urinary tract infections are common in pregnancy. This flowchart starts with addressing the pathophysiology of UTIs in pregnancy and lists the presentation as cystitis, pyelonephritis and asymptomatic bacteria. GPs are advised to request an MSU in all pregnant women with a suspected UTI. E Coli is the most common pathogen and treatment with antibiotics is shown to help in management. Management of asymptomatic bacteriuria ( as per CKS NICE ) is discussed separately. General practitioners should note that a finding of Group B-streptococcus should be shared with the ante-natal unit.
