Bladder cancer electrosurgery, also called transurethral bladder tumor electrosurgery, involves placing a surgical scope through the urethra into the bladder and then the tumor is removed from the inside. Cystectomy for bladder cancer involves placing a surgical scope through the external urethral orifice, passing through the urethra into the bladder, and then inside the bladder, where the tumor is removed from the inside by means of lasers and electrocautery. It is a good treatment for smaller, early bladder cancers that have not yet spread. Transurethral bladder tumor electrodessication is a kind of minimally invasive surgery, which has some limitations and is not particularly effective in removing tumors that are too large or too deep. For example, when the tumor grows from inside the cavity to outside the cavity, this surgery can only remove the tumor inside the cavity, while the tumor outside the cavity cannot be removed. Transurethral bladder tumor electrolysis is a relatively common clinical procedure, and patients are advised to relax, not to be overly nervous, and actively cooperate with the doctor.
