Agent-specific differences in sustained intraoperative hypotension during oral 5-Aminolevulinic acid-guided transurethral resection of bladder tumor: A retrospective observational study

Approximately one-fourth of patients undergoing oral 5-ALA-guided TURBT experienced sustained intraoperative hypotension, with spinal anesthesia showing a lower incidence than general anesthesia. Longer anesthesia and surgical durations increased the risk. The choice of anesthetic agents under general anesthesia also appeared to affect the risk of sustained hypotension. These findings highlight the importance of individualized anesthetic management to maintain hemodynamic stability during this procedure.
