To evaluate the efficacy and safety of intravesical hyaluronic acid (HA) instillation therapy for the prevention of radiation-induced cystitis in patients undergoing radiotherapy for bladder cancer.
Eligibility criteria

No distant metastasis (M0) IV. Transurethral resection of bladder tumor (TURBT): Maximal TURBT is available > Most tumors must be resected, and residual disease should be minimized.
Age ≥ 19
Karnofsky performance score (KPS) ≥ 70 or ECOG performance status 0~2
Patients who are candidates for bladder-preserving therapy, specifically those scheduled to undergo concurrent chemoradiotherapy (CCRT) instead of radical cystectomy.
Disqualifiers
Present of distant metastasis (M1)
Tumor invasion beyond the bladder wall into adjacent organs (T4b)
Non-urothelial carcinoma (including histologic variant) or predominant of non-urothelial components in mixed histology
