title: A prospective study comparing contamination rates between a novel mid-stream urine collection device (Peezy) and a standard method in renal patients.
abstract: BACKGROUND
  It is imperative that laboratories receive uncontaminated urine samples to avoid giving false-positive results and reduce antimicrobial use.
  
  
  OBJECTIVE
  The aim of the study was to investigate a novel urine collection device (Peezy) in a renal outpatient clinic to determine whether it reduced contamination of urine samples.
  
  
  METHODS
  The novel device was used in 420 renal transplant recipients and the results were compared with 424 matched historical controls, who used the standard method of urine collection. High epithelial cell counts on microscopy and mixed urine cultures were used to identify contaminated samples.
  
  
  RESULTS
  Peezy increased the rates of both epithelial cells and mixed growths in the urine samples when compared with the historical controls.
  
  
  CONCLUSIONS
  Further randomised studies in other more generalisable populations need to be performed.
