Last reviewed 01/2018
Preparation is unnecessary in the emergency situation.
Bowel preparation may be desirable to remove overlying faeces.
Fluid restriction for 4-6 hours before the examination ensures maximum concentration of contrast in the urine but is contraindicated in:
- neonates
- diabetics
- multiple myeloma
- poor renal function
A doctor and adequate resuscitation equipment must always be at hand because of the risk of allergic reaction to the contrast which varies from a mild urticarial rash to anaphylactic shock.
