         Percentage distribution of etiologic agents of urinary tract infections 
        among outpatients and inpatients, by ...
      Specimen Collection
        Suprapubic aspiration:
          the best method to avoid contamination. 
          Invasive and uncomfortable.
       Straight catheter technique:
          The next-best technique for obtaining urine specimens with minimal 
          contamination
          Too labor intensive, costly for routine use and  invasive
      Clean-catch midstream technique
           neither invasive nor uncomfortable.
           simple and inexpensive.
          can be performed in almost any clinical setting.
           there is no risk of introducing bacteria into the bladder
           there is no risk of complications. 
          Colony counts from urine specimens collected by this method correlate 
          reasonably well with those of specimens collected via suprapubic 
          aspiration or straight catheterization 
          The obvious disadvantage : the urine sample passes through the distal 
          urethra and can become contaminated with commensal bacteria.
     Discouraged specimens for culture
      Specimens from urinary catheters in place for 
       more than a few hours
         if required, the specimen must be taken
         from the sampling port of a newly inserted device. 
      Foley catheter tips 
      specimens from urinary diversions such as ileal 
       loops 
       Chronic nephrostomy collections and bagged 
       urine collections .
        
      Simple procedures to decrease the 
      contamination rate:
          cleansing of skin and mucous membranes 
        adjacent to the urethral orifice before 
        micturition
         collecting urine for culture from the 
        midstream
     Mandatory information on the test 
     requisition slip
      method of collection 
      date and time of specimen collection
      patient demographic information
      any clinically relevant information (e.g., 
       whether the patient was treated with 
       antimicrobial agents or whether 
       anatomic abnormalities, stones, or an 
       indwelling urinary catheter were 
       present)
