Bladder cancer resection usually requires long-term living with a urine bag, but bladder reconstruction patients mostly do not need to live with a urine bag for a long time. Radical cystectomy is usually used to treat: T2-T4a, N0-X, M0 invasive bladder cancer; high-risk non-muscle invasive bladder cancer T1G3 (high-grade) tumors; Tis that is ineffective on BCG therapy; recurrent non-muscle invasive bladder cancer; extensive papillary lesions that are uncontrolled by electrodesiccation and cystocele instillation therapy and non-urinary epithelial carcinoma of the bladder. Patients with bladder cancer who have only their bladder removed are unable to urinate and store urine normally after surgery and often have to carry a urinary bag or stoma bag for life. For patients given total bladder removal, some undergo bladder reconstruction surgery (ileal substitution bladder, colonic substitution bladder, etc.) and are trained to use the reconstructed ileum or colon for urine storage, and most patients can live without urine bags or catheters. If bladder cancer is suspected or diagnosed, it is recommended to go to a regular hospital for comprehensive assessment of the condition, follow the doctor’s instructions to cooperate with the treatment, and choose the appropriate treatment plan to avoid delaying the condition.
