Midstream Clean-Catch Urine Culture Obtained by Stimulation Technique versus Catheter Specimen Urine Culture for Urinary Tract Infections in Newborns: A Paired Comparison of Urine Collection Methods.
Med Princ Pract. 2020; 29(4):326-331.MP

Abstract

OBJECTIVE

The group of Herreros Fernández developed a new, safe, quick, and successful technique for collecting midstream clean-catch urine(MS-CCU) in newborns based on bladder stimulation and lumbar paravertebral massage maneuvers. The purpose of this study was to compare the contamination rates of catheter specimen urine (CSU) and MS-CCU by a lumbar/sacral stimulation technique in newborns.

MATERIALS AND METHODS

Full-term newborns ranging in age from 2 to 28 days who needed an investigation for a presumed urinary tract infection (UTI) were included in the study. Two samples, MS-CCU by lumbar/sacral stimulation technique and CSU, were collected consecutively for each patient. Suitable samples were obtained from 90 patients.

RESULTS

The contamination rate in MS-CCU cultures (n = 24/90, 26.66%) was higher than in CSU cultures (n = 9/90, 10%), and the difference was statistically significant (p = 0.039). Thirteen patients had UTI according to both samples (14.14%). In urine analysis, while there was no statistically significant difference in bacteriuria (p = 0.61) and nitrite positivity (p = 0.14) between patients with and without UTI, pyuria (p = 0.01) and leukocyte esterase positivity (p = 0.01) were higher in patients with UTI, and the difference was statistically significant.

CONCLUSION

The contamination rate in MS-CCU cultures was two and a half times greater than in the CSU culture samples. Thus, MS-CCU cannot replace the catheter for the diagnosis of UTI.
