Women who have had a mid-cavity delivery, an epidural top-up or spinal are at risk of urinary retention. Consider inserting an indwelling catheter (to be kept in place for 12 hours post delivery).
For those women who do not have an indwelling catheter, a fluid balance chart should be kept for 24 hours and the timing and volume of their first void noted. If they are unable to void within 4 hours, consider catheterisation.
If retention of urine is suspected, a post-void residual should be measured.
