Urologic oncology
-
There is increasing awareness that different anesthetic and analgesic techniques may impact outcomes after oncological surgery, generally through modifying effects on the immune system but potentially via other mechanisms including mitigating the surgical stress response. This narrative review aims to summarize the mechanisms underlying the effect of perioperative factors on oncological outcomes, with an emphasis on the available urologic literature. ⋯ This review highlights the role of regional anesthesia to improve oncoimmunological responses after surgery, potentially through decreased use of volatile anesthetics and opioids, decreased activation of the surgical stress response, and a direct local anesthetic-mediated anti-inflammatory effect. Available urological literature suggests an association of anesthetic type and outcomes for nonmuscle invasive bladder cancer and prostate cancer surgeries but the evidence is limited. Prospective studies are needed to further investigate the relationship between anesthetic technique and urologic oncological outcomes.
