Whether the varicocele surgery requires the insertion of a urinary catheter or not is related to the surgical method, as follows: 1. Most of the varicocele ligation under microsurgery requires general anesthesia, and the surgical time also includes the preoperative anesthesia preparation and the awakening time of the patient after anesthesia, so the overall surgical time is longer and requires the insertion of a urinary catheter, although the placement of the urinary catheter will bring a certain degree of discomfort to the patient, but it does not have a particularly big impact; 2. Minimally invasive vascular Interventional treatment belongs to local anesthesia surgery, the patient is awake during the operation, mainly through the intravenous route to the spermatic vein for drug injection, metal spring ring embolization, the operation time is shorter, generally 0.5-1 hours to complete, and the operation does not affect the urinary system, such as ureter, bladder, etc., usually no need to insert a catheter.
