Patients after cervical cancer surgery often carry urine bags around, this is different from some local hospitals where patients after cervical cancer surgery are catheterized from below, which is not very convenient to walk around, and the way the catheter is placed is a cystostomy. Why is it done this way? As one of the major gynecological surgeries, the vaginal resection is longer than the total uterine surgery in order to remove the tissue where the tumor may metastasize and infiltrate, and the parametrial tissue is more extensive than the total uterine surgery. In this way, the bladder is separated more thoroughly than in total uterine surgery. Also, in order to ensure that enough parametrial tissue is removed, the nerves of the cells that innervate the bladder are cut off when the ureter is freed during the surgery, so that after the nerves innervating the bladder are cut off, the patient cannot urinate by himself for a short time after the surgery, so a urinary catheter needs to be left in place. This allows the bladder to rest sufficiently so that its function can be restored. Adequate rest is only the first step to restore bladder function after cervical cancer surgery. The second step is functional exercise. Patients are trained to urinate on their own and try to empty as much as possible to avoid urinary retention. But why do we do cystostomy? Because for a cervical cancer surgery, the recovery time of bladder function after surgery varies, some patients need 2 to 3 weeks, some need 1 to 2 months. Cystostomy avoids leaving a urinary catheter through the urethra, which makes the patient’s activity not aspect and reduces the chance of urinary tract infection at the same time.
