Plain English summary of protocol
Background and study aims
A number of studies have provided information that self-bladder emptying (peeing in the toilet) from before Caesarean section and through recovery reduces the risk of urine infection without causing any problem during surgery (no bladder injury observed) or urination difficulty in the immediate recovery period.
However, one different type of study finds that when the catheter is removed immediately after the Caesarean is completed, 13.6% have difficulty peeing and need the catheter to be put back for a short time.
This is a study to compare the performances between peeing in the toilet (self-bladder emptying) with urinary bladder catheter placement at planned caesarean section to improve recovery and increase patient satisfaction.
The aim of this study is to evaluate the trial interventions as there is uncertainty about which is better or they may be equivalent. Information obtained from this study will help guide the management of future patients in similar circumstances.
Who can participate?
Participants include women aged 18 years and above, carrying a single healthy fetus (>37 weeks of gestation), who is planned to deliver by caesarean section.
What does the study involve?
Participants will be divided into two groups, one will urinate in the toilet and another group will have a urinary catheter inserted before surgery. The main outcome of this study is the rate of postpartum urinary retention (inability to pass urine after surgery) and participants' satisfaction with the given intervention.
What are the possible benefits and risks of participating?
There may or may not be any benefits to the participants. Information obtained from this study will help guide the management of future patients in similar circumstances.
For those allocated to self-emptying of bladder the specific risks are:
1. Operating field issue because the bladder is too filled up during surgery – the catheter will be inserted after the operation has begun
2. Injury to bladder – it will be repaired and the catheter has to be left in for about 1-2 weeks
3. Unable to pee immediately after surgery – catheter in and out or left in for up to 24 hours
For those allocated to the placement of a catheter the specific risks are:
1. Urine infection
2. Slower overall recovery from Caesarean section
3. After catheter removal, initial urination may be more uncomfortable and less satisfactory

| Scientific title | Self bladder emptying compared with catheter placement for planned caesarean section: a randomised controlled trial |
| Study objectives | 1. Pre-caesarean section indwelling bladder catheterisation vs self-voiding is superior with respect to post-partum urinary retention (PPUR) 2. Self-voiders are more satisfied with their bladder care compared to having an indwelling bladder catheter |
| Ethics approval(s) | Approved 05/11/2021, Medical Research Ethics Committee of University Malaya Medical Centre (Lembah Pantai, 59100 Kuala Lumpur, Malaysia; +60 3-79493209/2251; iresearch@ummc.edu.my), ref: 2021114-10756 |
| Health condition(s) or problem(s) studied | Women undergoing planned caesarean section |
| Intervention | Participants will be randomised into two arms, the self-emptying of the bladder arm or the indwelling bladder catheter arm. Patients randomised to self-emptying of the bladder arm will be asked to empty their bladder at OT call in the ward toilet before despatch to the operation theatre (in case of delay in starting of surgery they will be asked again to pass urine in the OT, ideally within 1 hour prior to start of surgery as per Senanayake et al). Patients randomised to indwelling bladder catheter will have their catheter inserted as per usual practice under aseptic technique using Foley catheter size 16F, after regional anaesthesia has been given in the operating theatre. The Foley catheter will be removed the next day according to current UMMC standard practice. |
