OBJECTIVE: To investigate the incidence of postpartum urinary retention (PUR) after cesarean delivery and determine which obstetric factors contribute to this problem. METHOD: A prospective study recruited 605 pregnant women who had a cesarean delivery. Each patient's postvoid residual bladder volume (PVRBV) was estimated with an ultrasound scan after first micturition. The women were divided into 2 groups: PUR (PVRBV > or =150 mL) and normal. Patients' characteristics, obstetric parameters, and prevalence of lower urinary tract symptoms at 3 months postpartum were compared. RESULT: The overall incidence of PUR was 24.1%. The incidence of overt and covert PUR was 7.4% and 16.7%, respectively. Morphine-related postoperative analgesia, multiple pregnancy, and low body mass index were significantly associated with PUR. At 3-month follow-up, 5.0% of patients had obstructive voiding symptoms and 9.1% had irritative voiding symptoms. CONCLUSION: Our results revealed PUR was a common phenomenon in patients who had a cesarean delivery, and morphine-related postoperative analgesia was the main contributing factor.
