Scenario Review

Mr Smith is commenced on IV fluids and encouraged to increase his oral intake. Over the next few days his urine output drops to 70-80 ml/hour and his IV fluids are stopped.

 

3 Days later his renal function blood tests show:

  • Sodium 140 mmol/L
  • Potassium 3.9 mmol/L
  • Urea is 12.8 mmol/L
  • Creatinine 124 µmol/L
 

His prostatic-specific antigen (PSA) test (taken in A&E prior to catheterisation) result is 4.2 ng/ml (normal < 4.5).

He is started on tamsulosin 0.4 mg once a day and is discharged with his urinary catheter in situ to be seen in clinic in 2 weeks for trial without catheter.
