Overview
Identify impaired bladder emptying and different patterns of leakage after birth, prevent overdistension, and arrange individual pelvic-floor rehabilitation and specialist assessment when recovery is abnormal.
Bladder recovery after birth involves sensation, coordination, mobility and healing. Pain, oedema, regional anaesthesia and pelvic nerve stretch may interfere with the normal urge to void or the ability to empty fully. A woman may report no urge despite a large bladder, or repeatedly pass small volumes without relief. Asking only whether she has passed urine can therefore miss significant retention. Record the first void, the volume when indicated and any concern about incomplete emptying.
Overt retention describes an obvious inability to pass urine, while incomplete emptying may be much less apparent. The immediate clinical aim is to prevent prolonged overdistension and identify reversible causes. Investigate when no urine has been passed within six hours after birth or removal of an indwelling catheter, and act earlier for pain or a palpable bladder. Review the timing of catheter removal, fluid intake, previous drainage, medication, mobility and perineal trauma. Drinking excessive amounts to force a void can worsen an already overfilled bladder.
