[Contribution of the microbiology laboratory to renal and urinary studies. Bacteriological examination of urine].

A. General considerations: 1. Microbiological condition of the normal urine and urinary tract; 2. Infections of the urinary tract. B. Possibilities of the laboratory of microbiology in renourinary investigations: 1. Detection and significance of pathogenic microorganisms in the urine; 2. Quantitative uroculture: a. The significance of urocultures in asymptomatic bacteriuria; b. The significance of bacteriuria in clinical diseases of the urinary tract. 3. Other diagnostic possibilities in urinary tract infections. 4. Possible microbiologic localization in urinary infections. a. Washing the urinary bladder; b. Urethral catheterism; c. Evidence of bacteria-antibody complexes in the urine; d. Bacteriologic localization pattern in bacterial urethritis and prostatitis. 5. Testing against antibiotics. C. Bacteriologic examination of the urine: 1. Collecting the urine for bacteriologic examination: a. Collecting from the middle jet: I) from women II) from men III) from imobilized patients IV) from children b. Collection by suprapubic puncture 2. Screening methods and tests 3. Methodology and diagnostic tests in urinary tract infections. a. Cultures; b. Follow up of the results. c. Reporting the results.
