Brief Summary
This project will conduct a large-sample, multi-center prospective clinical trial to further establish the safety and efficacy of BL-5ALA-PDT in preventing Non-Muscle Invasive Bladder Cancer (NMIBC) recurrence when compared to the usual postoperative perfusion chemotherapy regimen.

Conditions
Outcome Measures
Primary Outcomes (1)
Tumor recurrence rate 1 year after surgery
The recurrence rate of NMBC at 1 year after surgery was evaluated by regular urine routine, urinary B-ultrasound and cystoscopy
from date of randomization until the date of first documented Tumor recurrence
Secondary Outcomes (1)
Observe postoperative complications (focus on side effects beyond standard perfusion therapy)
from date of randomization until the date of first documented postoperative complications
Study Arms (2)
Standard infusion chemotherapy (including gemcitabine, mitomycin, Epirubicin, etc.)
ACTIVE COMPARATORStandard infusion chemotherapy (including gemcitabine, mitomycin, epirubicin, etc.) was dissolved in 50mL normal saline or glucose and perfused into the bladder for 60min. Perfusion can be performed within 24 hours after surgery, and then once a week for a total of 8 times, and then once a month until 12 months after surgery.
BL-5ALA-PDT
ACTIVE COMPARATORBl-5ala-pdt protocol: 1.5g 5ALA, dissolved in 50mL normal saline, was infused into the bladder for 2h before surgery and before each cystoscopy, and blue laser irradiation was performed under flexible cystoscopy at 30mW/cm2 for 21min. PDT was performed during the operation and at 3, 6, and 9 months after the operation.
Interventions
standard infusion chemotherapy (including gemcitabine, mitomycin, epirubicin, etc.), dissolved in 50mL normal saline or glucose, intravesical infusion chemotherapy, retained for 60min. Perfusion can be performed within 24 hours after surgery, and then once a week for a total of 8 times, and then once a month until 12 months after surgery
BL - 5 ala PDT - plan: 5ALA 1.5g (Shanghai Fudan-Zhangjiang Bio-Pharmaceutical Co.,Ltd), dissolved in 50mL normal saline, was infused into the bladder for 2 hours before surgery and before each cystoscopy. Blue laser irradiation was performed under a flexible cystoscope at 30mW/cm2 for 21min. PDT was performed during the operation and at 3, 6, and 9 months after the operation.
