When should a urinary catheter be inserted during interventional embolization for adenomyosis?

Adenomyosis interventional embolization usually requires the insertion of a urinary catheter before the operation to ensure normal urinary system function during and after the operation and to prevent bladder pressure during the operation. The urinary catheter is usually removed a few hours to 1 day after the operation.

1. Reasons for preoperative catheterization

Interventional embolization for adenomyosis is a minimally invasive interventional procedure that injects embolic materials into the uterine artery by puncturing the blood vessels to block the blood supply to the lesion and relieve symptoms. In order to prevent pelvic manipulation during surgery from compressing the bladder or causing poor urine flow, a urinary catheter needs to be inserted before surgery. At the same time, the urinary catheter facilitates recording changes in urine volume during surgery and helps doctors observe the patient's basal metabolic state during surgery.

2. Timing and operation of catheter insertion

The insertion of the urinary catheter is usually arranged after entering the operating room and before the preoperative anesthesia. This is to complete the operation in a relatively relaxed state of the patient to reduce discomfort. The insertion of the urinary catheter is performed by a professional nurse or doctor, and the operation requires a strict sterile environment to reduce the risk of infection. If you feel uncomfortable or worried about the insertion of the urinary catheter, you can communicate with the doctor before the operation. Local use of lubricants and antibacterial drugs can effectively relieve discomfort.

3. Time of postoperative catheter removal

After surgery, the catheter is usually removed within a few hours to 24 hours, depending on the patient's bladder function recovery. If the postoperative anesthetic is metabolized slowly or the patient is temporarily unable to urinate on their own, the doctor may recommend that the catheter be retained for a longer period of time. After the catheter is removed, if you find difficulty or discomfort in urinating, you need to inform the medical staff in time.

Inserting a urinary catheter before surgery is one of the necessary steps in the interventional embolization of adenomyosis, which provides protection for the surgical process and postoperative recovery. Postoperative review and following the doctor's advice are the key to ensuring a smooth recovery.
