DIAGNOSIS

• Unexplained fever > 38°C

• Infants with non-specific illness, failure to thrive, feeding difficulties

• Unexplained vomiting or abdominal pain

• The frequency of micturition, dysuria or enuresis.

• Prolonged jaundice in the newborn

• Suspected sexual abuse

• Haematuria / Hypertension

If Leucocytes & Nitrates negative but blood or protein are positive then, UTI is unlikely but always send for culture if clinical suspicion

CRITERIA FOR DIAGNOSIS

• A pure growth of > 100,000 organisms.

• Any growth in Suprapubic aspirate or in a catheter specimen.

Remember-

• The presence of a ‘mixed growth’ does not exclude UTI.
