Abstract

Objective: To create a reference curve for postvoid residual volume (PVRV) in asymptomatic postpartum women who are at low risk of developing postpartum urinary retention (PUR), a well-known complication in the immediate postpartum period.

Methods: This is a prospective observational study measuring PVRV after uncomplicated vaginal delivery. PVRV was assessed by transabdominal ultrasound using a portable ultrasound scanner within the first 26 h after delivery (PVRV 1) and on the day of discharge (day 2 or 3 postpartum) (PVRV 2). A PVRV of 150 mL or more was defined as the cut-off value for covert PUR.

Results: The prevalence of covert PUR was 7.1%. Primiparity, duration of second stage, and obstetric injury were correlated with higher PVRV 1. The median PVRV 1 was 21 mL and PVRV 2 was 11 mL. The subgroup of nulliparous women had a significantly higher PVRV 1 compared with multiparous women. At discharge, the majority (99.1%) of women had a PVRV of less than 150 mL.

Conclusion: Asymptomatic women were at low risk of developing PUR. However, women with a prolonged second stage may benefit from a routine postpartum assessment. Our results allow for a better understanding of PVRV in the early postpartum period.
