©2025 Relmada - All rights reserved NMIBC patient care journey 8 Treatment begins with TURBT (transurethral resection of bladder tumor) surgery to stage, risk - stratify, and treat patients. Following surgery, patients with HR - NMIBC typically receive intravesical BCG as adjunctive treatment Physicians diagnose suspected cases of bladder cancer using cystoscopy and cytology. (Most common presenting symptom is blood in urine.) For patients with recurrent disease, repeat TURBT +/ - alternative intravesical treatments are used, including chemotherapies such as Gem/Doce Regular cystoscopies and urine cytology (up to every 3 months) are used to monitor patients and assess for recurrence 1 2 3 4 5 Based on AUA/SUO Practice Guidelines, 2024 (Event April 28, 2025 (Holzbeierlein et al.
