Abstract

Abstract : Purpose: For patients with persistent irritative lower urinary tract symptoms, such as dysuria and urinary frequency, evaluation for the atypical organisms Ureaplasma and Mycoplasma has been a common part of care. However, these species are genitourinary colonizers and have not been established as causative pathogens in chronic lower urinary tract symptoms. We therefore sought to evaluate diagnostic testing patterns for Ureaplasma and Mycoplasma and characterize the associations of these bacteria with irritative lower urinary tract symptoms using molecular detection techniques. Materials and Methods: Ureaplasma/Mycoplasma testing patterns for 2019 were assessed using an anonymized data repository. Clean catch urine specimens (179) were collected prospectively from female and male patients with and without irritative lower urinary tract symptoms. Quantitative polymerase chain reaction evaluated urinary Ureaplasma and Mycoplasma DNA concentrations, while next-generation sequencing assessed the relative abundance of Ureaplasma and Mycoplasma within the urinary bacterial population. Results: Ureaplasma/Mycoplasma testing was common, with 575 tests performed in 2019 in our community hospital system. In our cohort, Ureaplasma and Mycoplasma were identified in similar proportions in symptomatic and asymptomatic subjects: 25% of female controls and 27% of females with lower urinary tract symptoms and 9.5% of asymptomatic males and 3.3% of men with symptoms (p=0.87 and p=0.91 for females and males, respectively). Regression analysis revealed that both abundance and concentrations of Mycoplasmataceae correlated negatively with a range of irritative lower urinary tract symptoms, including dysuria and urethral pain. Conclusions: A statistically significant negative correlation of Ureaplasma/Mycoplasma levels with a variety of lower urinary tract symptoms suggests that polymerase chain reaction-based Mycoplasmataceae detection has little diagnostic benefit in assessment of chronic irritative urinary symptoms.
