Mitomycin C (MMC)
When administering neoadjuvant intravesical instillations, instruct the patient to lie flat on the treatment bed and cover with a waterproof pad. Disinfect the perineal area 2-3 times. Under sterile conditions, insert a catheter and drain the bladder of urine completely. Slowly instill the prepared instillation solution (mitomycin) into the bladder. If the patient experiences pain during the instillation, stop the infusion immediately, and continue when the pain subsides. If the patient still cannot tolerate it, discontinue the instillation treatment for this session. After the medication is instilled into the bladder, the catheter can be removed immediately or left in place. Instruct the patient to hold their urine for as long as possible under suitable conditions for 2 hours, and to change positions intermittently while the medication is retained in the bladder. The neoadjuvant intravesical instillation cycle is twice (one day and 4 h before en-bloc surgery)
