Patients will be randomized into each group at a ratio of 1:1., primaryPurpose: TREATMENT, maskingInfo masking: SINGLE, maskingDescription: The care provider carrying out the heterocatheterization will be blinded to the participant's randomization group., whoMasked: CARE_PROVIDER, enrollmentInfo count: 500, type: ESTIMATED, armsInterventionsModule interventions name: Spontaneous urination during the hour before caesarean section., interventions name: Systematic bladder catherization during caesarean section., outcomesModule primaryOutcomes measure: Necessity of heterocatheterization within 24 hours following the cesarean section., primaryOutcomes measure: Experience of childbirth, primaryOutcomes measure: Duration of preoperative preparation, primaryOutcomes measure: Operating time, primaryOutcomes measure: Duration of post-operative hospitalization, primaryOutcomes measure: Time to resume ambulation, primaryOutcomes measure: First urination, primaryOutcomes measure: Pain during the first urination or the first heterocatheterization, primaryOutcomes measure: Discomfort during the first urination or the first heterocatheterization, primaryOutcomes measure: Additional prescription for painkillers, primaryOutcomes measure: Urinary infection detection, primaryOutcomes measure: Occurrence of surgical difficulties, primaryOutcomes measure: Occurrence of operative complications, primaryOutcomes measure: Amount of bleeding, primaryOutcomes measure: Presence of symptoms suggestive of a urinary infection, primaryOutcomes measure: Presence of functional signs (dysuria, incontinence, delayed bleeding or others), primaryOutcomes measure: Time before resuming spontaneous urination, eligibilityModule sex: FEMALE, minimumAge: 18 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: Montpellier University Hospital, city: Montpellier, zip: 34295, country: France, contacts name: Martha DURAES, MD, role: CONTACT, phone: +334.67.33.65.32, email: m-duraes@chu-montpellier.fr, contacts name: Martha DURAES, MD, role: PRINCIPAL_INVESTIGATOR, contacts name: Florent FUCHS, MD PhD, role: SUB_INVESTIGATOR, geoPoint lat: 43.61092, lon: 3.87723, locations facility: Nîmes University Hospital, city: Nîmes, zip: 30029, country: France, contacts name: Audrey LAMOUROUX, MD, role: CONTACT, email: audrey.lamouroux@chu-nimes.fr, contacts name: Audrey LAMOUROUX, MD, role: PRINCIPAL_INVESTIGATOR, contacts name: Vincent LETOUZEY, MD PhD, role: SUB_INVESTIGATOR, geoPoint lat: 43.83333, lon: 4.35, hasResults: False
