Clinical Trial Summary

The hypothesis of this trial is that the absence of systematic bladder catheterization in patients performing spontaneous urination in the hour preceding the planned cesarean section under spinal anesthesia would not lead to more bladder heterocatheterization for postpartum urinary retention (RUPP) in the 24 hours post-cesarean section than systematic intraoperative bladder catheterization up to 2 hours post-surgery.

Clinical Trial Description

Introduction: The recommendations for the clinical practice of cesarean section, published by the National College of French Gynecologists and Obstetricians (CNGOF) in 2022, have led to a standardized surgical technique. During this surgery, urinary catheterization is use and allows to avoid urinary retention and give a better chirurgical exposition. But it presents also risks as urinary infection development or pain and discomfort for the patient. Actually, the CNGOF wonders if for women having a cesarean section, preoperative spontaneous urination would reduce urinary complications compared to the placement of an intraoperative bladder catheter. The current literature does not allow to respond satisfactorily to this question. This is why C2S study proposes a cesarean section without urinary catheterization following a spontaneous miction. Aim: The aim of this trial is to evaluate the rate of bladder heterocatheterization in cases of postpartum urinary retention (RUPP) within 24 hours following a planned cesarean section under spinal anesthesia, according to two management methods: the absence of intraoperative catheterization associated with spontaneous urination in the hour preceding the cesarean section versus systematic intraoperative bladder catheterization up to 2 hours postoperatively. Moreover, this trial will allows to evaluate benefits and risks of the urinary catheterization absence. Methods: Following the aim of the trial, it is a prospective randomized study comparing these two treatment modalities in a randomized controlled study with a high level of evidence. In order to meet the objectives of the study, 500 patients will be included. Patients will be informed by the investigator during the Caesarean section scheduling consultation, and included the day before their cesarean section during their hospitalization. They will be randomized by the investigator on the morning of their cesarean section. In the hour before the cesarean section, participants will be asked to urinate spontaneously. Once the patient is installed on the operating table, the investigator will carry out an ultrasound check using bladder scan of the post-void residue. In the event of a post-void residue of more than 150 ml, the participant will be removed from the research. After the surgical closure of the cesarean section (H0) starts the postpartum follow-up. - 2 hours after H0 (H2), an ultrasound check by bladder scan will be carried out in the recovery room, and after collecting the first spontaneous urination, the urine will be quantified either using a graduated cup. - After the first urination or 6 hours after H0 (H6), an ultrasound check of the remaining bladder volume will be carried out by bladder scan. - At H6, a bladder heterocatheterization will be carried out in the following cases: - Complete RUPP: absence of spontaneous urination - Partial RUPP: volume urinated less than the post-void residue (only if the volume urinated > 150 ml) - After the first urination or the bladder heterocatheterization, a cyto-bacteriological examination of the urine (ECBU) will be carried out. - Moreover, the patient will evaluate their pain and discomfort felt during their first urination or heterocatheterization using a visual numerical scale (EVN). - The clinical team will collect complications and adverse events. - 24 hours after H0 (H24), a ECBU will be realised and the patient's experience of childbirth will be assessed using the Questionnaire For Assessing the Childbirth Experience (QEVA). - At H24 and at 6 weeks after the caesarean section (W6), the investigator will collect any additional prescriptions for painkillers. - From the day of the caesarean section to the last visit at 6 weeks after the surgery, potential adverse events will be collected. ;
