Abstract
With the rapid acceleration of population aging in China, the number of elderly patients undergoing urological surgery has increased year by year, accompanied by a rising incidence of postoperative delirium (POD). This article provides a comprehensive review of the current status, clinical characteristics, and associated risk factors of postoperative delirium in elderly urological patients. Patient-related factors such as advanced age, multiple comorbidities, cognitive impairment, and malnutrition significantly increase the risk of POD. In addition, perioperative factors—including inappropriate preoperative medication use, the extent of surgical trauma, choice of anesthesia, and inadequate postoperative pain management—also play critical roles. A thorough understanding of these risk factors is beneficial for clinicians to develop targeted preventive strategies and to improve postoperative recovery outcomes in elderly patients.
