ObjectivesTo investigate the relationships between various obstetric parameters and postpartum urinary retention, and to offer some clinical guidance for resolution of urinary retention problems.DesignAn observational prospective study.SettingA private teaching hospital medical centre.PopulationA total of 2,866 vaginally delivered women were recruited with 114 women classified as urinary retention group and the remaining 2752 women categorised as control group.Main Outcome Measures And ResultsWomen in the urinary retention and control groups did not differ significantly in terms of age, fetal head circumference and fetal birth weight. Women suffering from postpartum urinary retention demonstrated significantly longer labour duration, more nulliparity and epidural analgesia and higher percentages of instrument-assisted delivery and vaginal or perineal damage.ConclusionNulliparity, longer labour course, instrumental delivery, extensive vaginal and perineal laceration and use of epidural analgesia were contributing obstetric factors to postpartum urinary retention. Long-term follow-up showed that the problems of all but three of the 114 women, who complained of persistent minor urinary symptoms, were eventually resolved.
