Purpose of Paper

This paper investigated the effects of using Peezy devices versus traditional collection in sterile jugs on cellular and bacterial contamination of urine specimens from female post-kidney transplant patients.

Conclusion of Paper

After switching to Peezy devices for urine collection, specimens contained significantly more white blood cells (WBCs) and epithelial cells than prior to the switch, when urine was collected in sterile jugs.

Studies

  1. Study Purpose

    This study investigated the effects of using Peezy devices versus traditional collection in sterile jugs on cellular and bacterial contamination of urine specimens from female post-kidney transplant patients. Contamination levels in 420 mid-stream urine specimens from female patients collected into Peezy devices were compared to 424 mid-stream urine specimens collected in sterile jugs. Urine specimens were analyzed by light microscopy and culture.

    Summary of Findings:

    Specimens collected in Peezy devices had more WBC and epithelial cells per mm3 (P<0.001 and P=0.008, respectively) and a trend toward more mixed growth cultures (9.3% versus 5.6%, P=0.1).
