Advanced bladder cancer recurrence requires CT, MRI, cystoscopy and other examinations to clarify the patient’s current pathology and receive conservative or surgical treatment. Most bladder cancers are non-muscle invasive bladder cancers, and transurethral cystectomy of bladder tumors is the main treatment option, but the postoperative tumor residual rate is not optimistic, in addition to the uncertainties of tumor number, size, and grade, as well as carcinoma in situ. Some studies claim that the recurrence and progression rates within 1 year after surgery can reach 15%-61% and 1%-17%, respectively. Surgery combined with intravesical adjuvant perfusion is the main treatment option for non-muscle invasive bladder cancer at home and abroad, which can effectively reduce the recurrence rate and kill the free tumor tissues/cells after surgery. If recurrence occurs after surgery, corresponding treatment can be chosen according to the situation: 1. Surgical treatment: Surgical treatment is usually preferred, and according to the recurrence situation, bladder-preserving surgery (transurethral cystectomy of bladder tumor, etc.), radical cystectomy, partial cystectomy and other surgeries will be chosen, and after surgery, intravesical instillation therapy or adjuvant chemotherapy will be chosen according to the situation. 2. Conservative treatment: If surgery is not possible, conservative treatment is needed to adopt bladder instillation chemotherapy, radiation therapy and other treatment modes to help stabilize the patient’s condition and prolong the survival time as much as possible. Patients with recurrent bladder cancer should pay attention to it. If bladder tumor is suspected or diagnosed, it is recommended to go to regular hospitals for comprehensive assessment of the condition, follow the doctor’s instruction to cooperate with the treatment, and choose the appropriate treatment plan in order to avoid delaying the condition.
