[The Effect of Naldemedine Tosylate on the Postoperative Course of Robot-Assisted Radical Cystectomy].

Radical cystectomy is an invasive procedure frequently followed by postoperative complications. Although the protocol of enhanced recovery after surgery (ERAS) is used in the postoperative course, several components of the ERAS protocol may increase the workload of medical workers. In this study, we added naldemedine tosylate only to routine postoperative management instead of using the ERAS protocol and evaluated the effect on the postoperative course of robot-assisted radical cystectomy (RARC). We retrospectively investigated 58 patients who underwent RARC from May 2015 to February 2022 at our hospital and evaluated the postoperative complications, such as ileus and urinary tract infections, and, length of hospital stay (LOS). We used naldemedine tosylate for the patients who underwent RARC after November 2019. As a result, naldemedine tosylate reduced 26.8% of postoperative complications within 30 days after the operation (p＝0.041) and shortened LOS 8 days (p＝0.018). Naldemesine tosylate improved the postoperative course of RARC.
