Urinary tract infection in children is a world-wide problem and some management is required in correct bacteriological diagnosis. Recently, dip-slide culture method is conveniently used in Europe for systematic screening of bacteriuria and its reliability for detection of bacteriuria has been reported by many investigators.
The authors tested the accuracy of a dip-slide system “Uromedium” developed in our country by comparing the results with that from the pour-plate method.
In 57 to 100 percent of 545 cases, results obtained from Uromedium were accorded with that from the pour-plate method, and the specificity of Uromedium was estimated 73 percent. Bacterial numbers in urine specimens determined by both method ranged below 102 to over 106 per ml and several species of gram-positive cocci, gram-negative bacilli, and fungus were isolated. For all the organisms linear regressive lines were obtained between bacterial numbers determined by both methods and the coefficients (γ) were 0.82 to 0.98. These findings suggest that “Uromedium” is a satisfactory method for systematic screening of bacteriuria and diagnosis of urinary tract infection.
