Single Catheterization for Preventing Postpartum Urinary Retention in Early Postpartum Voiding Failure: A Propensity...

Area of Science:

• Obstetrics and Gynecology
• Urology
• Postpartum Care

Background:

• Postpartum urinary retention (PUR) is a common complication.
• Evidence for single postpartum catheterization in preventing PUR is limited.
• Early voiding failure is defined by bladder volume ≥ 300 mL and inability to void spontaneously.

Purpose of the Study:

• To investigate the effectiveness of single postpartum catheterization in preventing PUR.
• To analyze the impact on different subtypes of PUR (overt and covert).
• To assess effects on spontaneous voiding and need for indwelling catheterization.

Main Methods:

• Retrospective cohort study utilizing real-world data.
• Comparison between single catheterization and non-catheterization groups.
• Stabilized inverse probability of treatment weighting (sIPTW) used for confounder adjustment.

Main Results:

• Single catheterization was associated with significantly lower risks of overall PUR and covert PUR.
• No significant association was found with overt PUR, spontaneous voiding, or number of induced voiding attempts in the primary analysis.
• Within 2 hours postpartum, single catheterization also reduced indwelling catheterization risk and induced voiding attempts.

Conclusions:

• Single postpartum catheterization is effective in reducing PUR and covert PUR in women with early voiding failure.
• The benefits extend to reduced indwelling catheterization and fewer voiding attempts when performed within 2 hours.
• Prospective validation of these findings is recommended.
