摘要Objective Coronavirus disease 2019(COVID-19)can result in fatigue and post-exertional malaise;however,whether severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection exacerbates lower urinary tract symptoms(LUTS)is unclear.This study investigated the association between prenatal SARS-CoV-2 infection and postpartum LUTS.Methods A multicenter,retrospective cohort study was conducted at two tertiary hospitals in China from November 1,2022,to November 1,2023.Participants were classified into infected and uninfected groups based on SARS-CoV-2 antigen results.LUTS prevalence and severity were assessed using self-reported symptoms and the Incontinence Impact Questionnaire-Short Form(IIQ-7).Pelvic floor muscle activity was measured using electromyography following the Glazer protocol.Group comparisons were performed to evaluate the association of SARS-CoV-2 infection with LUTS and electromyography parameters,with stratified analyses conducted using SPSS version 26.0.Results Among 3,652 participants(681 infected,2,971 uninfected),no significant differences in LUTS prevalence or IIQ-7 scores were observed.However,SARS-CoV-2 infection was an independent factor influencing the electromyographic activity of the pelvic floor muscles(mean tonic contraction amplitudes),regardless of delivery mode(P=0.001).Conclusion Prenatal SARS-CoV-2 infection was not significantly associated with an increased risk of postpartum LUTS but independently altered pelvic floor muscle electromyographic activity,suggesting potential neuromuscular effects.
