Musselwhite et al identified risk factors for acute urinary retention following delivery. These can help to identify a patient who may benefit from closer monitoring to detect this complication. The authors are from the Calgary Health Region in Calgary, Canada.


Risk factors for acute postpartum urinary retention:

(1) use of narcotics during delivery (including epidural anesthesia)

(2) second stage of labor >= 60 minutes

(3) perineal damage

(4) use of instruments (forceps, etc) for delivery


The individual odds ratios for any single risk factor is relatively low, so that multiple risk factors often are required for significant risk.
