[Diagnostic value of the detection of antibody-bound bacteria in the urine]

By means of the immunofluorescence technique 107 patients with chronic pyelonephritis and 43 patients with an infection of the lower urinary tract were examined for the presence of antibody-containing bacteria in the urine. Here in 84 out of 107 patients (78.5%) with a chronic pyelonephritis the positive proof could be made, whereas in 39 out of 43 patients (90.6%) with an infection of the lower urinary tract no antibody-containing bacteria were found. The test may be recommended as a relatively simple, riskless and evident method for the diagnostics of pyelonephritis.
