Acute urinary retention in early pregnancy: how far should the investigation go?

Acute urinary retention in early pregnancy is a rare but serious problem. In most cases a causative factor can be identified. In the absence of a readily identifiable causative factor following basic investigation, the further diagnostic and treatment approach can be a challenge, as there are no defined guidelines. A case of acute urinary retention in early pregnancy with no readily identifiable cause managed by patient self-intermittent catheterization on outpatient basis is hereby reported.
