A Prospective Study Comparing Contamination Rates Between a Novel Mid-Stream Urine Collection Device (Peezy) and a Standard Method in Renal Patients

S Collier et al. J Clin Pathol.

Abstract

Introduction: It is imperative that laboratories receive uncontaminated urine samples to avoid giving false-positive results and reduce antimicrobial use.

Aim: 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.

Keywords: Diagnosis; Infections; Transplantation; Urine.
