Spinal Anesthesia Provides Longer Administration Time for Postoperative Intravesical Chemotherapy after TUR-B Operation

Purpose: The aim of this study was to investigate the tolerability of postoperative early intravesical chemotherapy session after transurethral resection of the bladder tumor (TUR-B) according to the different anesthesia types. Methods: The study was conducted between February 2017 and June 2020. Patients who were given intravesical mitomycin (MMC) 40 mg after TUR-B were included. Patients’ risk categories (low, medium, and high) were determined according to the European Association of Urology (EAU) risk stratification system based on the tumor number, size ( 0.05). High-grade tumors were higher in group S (23.9 vs. 11%; p = 0.008). Requirement of analgesic (53.9 vs. 91.5%; p = 0.00) and termination of therapy
