Prolonged second stage of labor in epidural analgesia deliveries tied to increased risk of postpartum urinary retention

The study revealed the following findings:

• After adjustment by propensity score matching for age, body mass index, being primiparous, and labour induction as covariates, the analysis of the incidence of postpartum urinary retention revealed that the epidural analgesia group exhibited a significantly higher postpartum urinary retention rate than the no epidural analgesia group (30% versus 11%).
• The investigation results regarding risk factors for postpartum urinary retention in the epidural analgesia group obtained through a univariate analysis showed that being primiparous and having a prolonged second stage of labour were significantly correlated with postpartum urinary retention.
• Multivariate analysis indicated that a prolonged second stage of labour was an independent risk factor for postpartum urinary retention (odds ratio: 3.18).
• All patients recovered from postpartum urinary retention by day 4.

"The findings show that the postpartum urinary retention rate after delivery using epidural analgesia was 25.7%," the researchers wrote. "In the case of epidural analgesia deliveries, a prolonged second stage of labour was an independent risk factor for postpartum urinary retention."
