Postpartum urinary retention after vaginal delivery

Area of Science:

• Obstetrics
• Urology
• Women's Health

Background:

• Postpartum urinary retention (PUR) is a common complication after vaginal delivery.
• Understanding the incidence and risk factors for PUR is crucial for effective management.

Purpose of the Study:

• To determine the incidence of covert and overt postpartum urinary retention (PUR) after vaginal delivery.
• To identify obstetric variables associated with the development of PUR.

Main Methods:

• A cross-sectional study involving 771 women who delivered vaginally.
• Transabdominal ultrasound was used to measure postvoid residual bladder volume and diagnose PUR.
• Obstetric data, including mode of delivery and labor duration, were collected and analyzed.

Main Results:

• The overall incidence of PUR was 10.9% (84/771), with 10.6% (82/771) being covert PUR and 0.3% (2/771) being overt PUR.
• Instrumental delivery was significantly associated with an increased risk of PUR (P=0.03).
• A labor duration exceeding 700 minutes was a strong predictor of PUR, with a significant ROC curve (P<0.001).

Conclusions:

• Covert postpartum urinary retention is significantly associated with instrumental delivery.
• Prolonged labor (over 700 minutes) is a key predictor for developing postpartum urinary retention.
