Postpartum urinary retention: Absolute risk prediction model.

Our study identified non-Caucasian ethnicity, nulliparity, and a BMI <30 kg/m2 at the end of the pregnancy as minor and epidural analgesia, meconium-stained amniotic fluid, vaginal nonoperative birth, vacuum extraction, pushing stage ≥60 minutes, and perineal tear as major independent risk factors for PPUR.
