Abstract Bladder cancer is a common cancer in the urinary system. The current common treatments include surgery and chemotherapy. However, the efficacy of patients with advanced bladder cancer is still unsatisfactory. In recent years, with the advent of immunotherapy represented by immunological checkpoint inhibitors such as programmed cell death 1 (PD-1)/programmed cell death ligation 1 (PD-L1) inhibitors, new treatments for advanced bladder cancer have emerged. PD-1/PD-L1 inhibitors block PD-1/PD-L1 binding, thereby blocking negative immune regulatory signals, then enhancing anti-tumor immune activity. This article will review the principles, current status and adverse effects of PD-1/PD-L1 inhibitors in the treatment of advanced bladder cancer through analyzing data and results in clinical trials, and provide assistance for the clinical treatment of patients with advanced bladder cancer.
