[Comparison of the results of the measurement of O2 consumption with a conventional bacteriologic method for urine obtained by bladder puncture].
A method is described which utilizes the O2 consumption of aerobes and facultative aerobes from urinary tract infections for their detection. Urines obtained by puncture and the corresponding midstream urines were examined for verification. Irrespective of secondary contamination and the presence of non-causative organisms, the O2 consumption method permits the detection of a bacterial urinary tract infection within 1 h. When this method was used, a comparison between midstream urine and urine obtained by puncture showed a complete coincidence. The O2 method has shown a sensitivity of 96.9% at a specificity of almost 100% for bacterial concentrations of more than 10(5)/ml in the urine obtained by puncture.
