title: [Biochemic evidence of the presence of urine in a drain following surgery].
abstract: OBJECTIVE
  Evaluation of the laboratory investigations of the postoperative wound drains liquids containing urine and establishing the borderline levels for confirmation of the urine presence. PATIENTS GROUP AND THE METHODS: Biochemical analysis of the drain liquids, urine and blood serum from the 34 patients with confirmed urine leak out of the urinary tract. The urea, creatinine, natrium, potassium and chloride levels were measured in all samples.
  
  
  RESULTS
  The mean natrium, potassium, chlorides, urea and creatinine mean levels were 93.8 mmol/l, 15.9 mmol/l, 77.0 mmol/l, 73.3.
