CT scan shows a distended bladder associated with bilateral mild ureterohydronephrosis. No other relevant findings.
An inadequate clinical examination failed to perceive a mild abdominal distention in the hypogastric region and a history of recent absence of urination. Patient was catheterised and obtained symptoms relief.
Acute urinary retention as in this case is usually managed clinically, without image evaluation. Immediate management of it requires bladder decompression with catheterisation.
Anatomical and functional disturbs are listed as causes for acute urinary retention, such as infection, post-operative pain, and operative analgesia or anaesthetic (e.g. epidural).
