Abstract
INTRODUCTION AND HYPOTHESIS: Postpartum urinary retention requires timely detection and intervention as late detection can lead to long-term voiding dysfunction; however, trends in the prevalence of urinary retention during the postpartum period remain unclear. This systematic review and meta-analysis aimed to estimate the pooled overall prevalence of overt and covert urinary retention in women after vaginal delivery and the difference in prevalence within 4 days after delivery. METHODS: MEDLINE, CINAHL, Ichu-shi web, and J-stage databases were searched up until October 2020. Two researchers screened and included observational studies reporting the prevalence of urinary retention up to 4 days postpartum based on inclusion criteria. The overall prevalence of overt and covert urinary retention was calculated. RESULTS: From 24 studies, the overall overt and covert urinary retention prevalence rates were estimated to be 1% and 13%, respectively. The prevalence of overt urinary retention over time was 2% at 6 h postpartum, 1% at 6-12 h, and 3% from postpartum to 24 h postpartum. The prevalence of covert urinary retention over time was 19% (6 h postpartum), 15% (24 h postpartum), 11% (1 day postpartum), 7% (2 days postpartum), 8% (3 days postpartum), and 0.1% (4 days postpartum). CONCLUSIONS: By postpartum day 4 after vaginal delivery, 14% of women were found to have experienced urinary retention. The highest prevalence was observed at 6 h postpartum, suggesting that urinary retention could be identified at 6 h postpartum.
