Objetive: To investigate the prevalence and potential risk factors for postpartum voiding dysfunction (PPVD).Methods: A retrospective observational study was performed in a university hospital center between January 2018 and April 2019. Women with PPVD criteria postpartum were diagnosed and treated. Gestational, delivery, and puerperium characteristics were compared between women with and without PPVD.Results: A total of 1894 out of 2308 deliveries (81%) were vaginal, 73 (9.85%) had PPVD and 13.7% were severe. Epidural analgesia (odds ratio [OR] 7.72, 95% confidence interval [CI],1.02-58.37), operative vaginal delivery (OR 2.23, 95% CI,1.01-4.93), birthweight >4000g (OR 3.7, 95%CI,1.4-9.73), and previous cesarean delivery (OR 6.54, 95% CI, 2.2-19.2) were independent risk factors for PPVD.Conclusion: PPVD is a relatively common finding that complicates around 10% of vaginal deliveries. Epidural analgesia, birthweight, operative vaginal birth, and having a previous cesarean delivery are independent risk factors for PPVD. In order to prevent PPVD, more research on PPVD risk factors is needed. [ABSTRACT FROM AUTHOR]
