RCT About Two Different Regimens of Clean Intermittent Catheterization in Women With Overt Postpartum Urinary Retention

A randomized controlled trial of two different regimens of intermittent catheterization in women with overt postpartum urinary retention. Participants will be randomized to one of two groups with different cut-offs for accepted postvoid residual urine (150 ml vs 250 ml). Primary endpoint is be the time to regain normal bladder function in each group. Secondary endpoints are 1) presence/absence of bacteriuria or urinary tract infections, 2) the duration of hospital stay, 3) scores on the adapted version of the German pelvic floor questionnaire section about bladder function and postpartum symptoms. The calculated sample size is 96 (48 in each group).
