Usually people who undergo laparoscopic surgery for varicocele usually do not need a urinary catheter, and patients should actively cooperate with their doctors. Laparoscopic surgery for varicocele usually refers to clinical laparoscopic high ligation of the spermatic vein, i.e., the ligation of the internal spermatic vein from the internal loop opening under laparoscopy. The procedure is less invasive, more effective and quicker to recover, so most patients do not need a urinary catheter and can usually urinate on their own on the day after the operation without excessive worry. For a small number of patients who undergo laparoscopic high ligation of the spermatic vein, if they have difficulty urinating, a urinary catheter can be inserted as prescribed by the doctor to minimize the occurrence of urinary retention and bladder rupture. After surgery, patients should strengthen personal hygiene care, keep the surgical wound clean and dry to prevent infection. It is recommended that those who need laparoscopic vesicoureteral ligation should consult a regular hospital for examination and treatment in order to increase the chance of success of the surgery. If there is frequent urination, urgency of urination, or pus flowing from the surgical wound after the surgery, it is necessary to inform the doctor in time to deal with it.
