Question 127 · LEK · Urinary tract infections
A 84-year-old patient was referred to a hospital emergency department by a medical emergency team because of the sudden deterioration of his general condition, hypotension, delirium and a subsequent loss of contact (unconsciousness). A resident of the nursing care unit, he was suffering from dementia and was persistently catheterized because of benign prostate hyperplasia. There was visible cloudy urine in the bag. The workup for the diagnosis of urosepsis includes bacteriological examination of the following samples:
- A. blood and urine obtained directly from the catheter.
- B. urine obtain from the bag after its replacement.
- C. blood and urine taken after catheter rinsing with physiological saline solution.
- D. urine obtained through bladder puncture.
- E. blood and urine after re-catheterization.
Hint
A long-term catheter is covered with biofilm; think about how to obtain urine that reflects bladder infection rather than catheter colonisation.
