If the cesarean section is well prepared before the operation, you can go to the operating table after inserting the urinary catheter, and after sterilization and anesthesia, the operation can be carried out, and the urinary catheter can be removed 1-2 days after the operation. Since the mother is unable to urinate on her own during the operation, not inserting a urinary catheter may lead to urinary retention or even bladder rupture. In addition, if the bladder is full during the operation, it will also affect the operation. Inserting a urinary catheter is also convenient for the anesthesiologist to decide the amount of intraoperative rehydration and understand the patient’s cardiac and renal functions by observing the urine volume. Without a urinary catheter, involuntary spillage of urine may cause contamination of the surgical area or intraoperative infection. The catheter can be removed 1-2 days after the operation when the bladder function has recovered and the woman can urinate on her own. Women undergoing cesarean section are advised to follow the doctor’s instructions, get out of bed as soon as possible after the operation, try to remove the urinary catheter as soon as possible to avoid urinary tract infections, and consult the doctor if they feel unwell.
