In radical cystectomy (RC), which carries high risks of complications and mortality, optimizing fluid management poses a significant challenge due to the absence of definitive guidelines. Aim: the purpose of this study was to investigate the effects of intravenous fluid administration on postoperative complications in patients undergoing RC. Material and methods: This study involved 288 patients who underwent laparoscopic RC and urinary diversion from 2018 to 2022. ERAS protocols were implemented for all patients. Participants were divided into four groups based on the type of urinary diversion (ureterocutaneostomy vs. ileal conduit) and the intraoperative fluid volume input (less than 1000 mL vs. more than 1000 mL). Postoperative complications were evaluated at 30 and 90 days post-surgery using the Clavien-Dindo scale. The fluid management effectiveness was measured using the absolute Vascular Bed Filling Index (aVBFI) and the adjusted Vascular Bed Filling Index (adjVFBI). Results: The UCS is associated with a lower risk of increased severity of postoperative complications. The administration of more than 1000 mL of fluids was associated with a higher risk of complications (p = 0.035). However, after adjusting for the duration of the surgery and BMI, this association did not hold statistical significance, indicating that fluid volume alone is not a direct predictor of postoperative complications. At aVBFI values between zero and eight, urinary diversion using the UCS method is associated with a lower risk of complications compared to the IC. When aVBFI equals eight, the differences in the severity of complications between the UCS and the IC are minimal. However, when aVBFI exceeds eight, the IC is associated with fewer complications during the 30 days post-operation compared to the UCS. The correlation between the adjVFBI (B = \u22120.27; 95% CI: \u22120.45 to \u22120.08; p = 0.005) and the severity of complications up to 30 days postoperatively is similar to that seen with the aVBFI. Similarly, the correlation of the adjVFBI with the method of urinary diversion (B = 0.24; 95% CI: 0.06 to 0.43; p = 0.011) resembles that of the aVBFI. The volume of fluids administered and the indices aVBFI and adjVFBI did not influence the occurrence of complications 90 days postoperatively. Conclusions: The volume of fluids administered is not a factor directly affecting the occurrence of complications following RC when the ERAS protocol is used. The amount of intraoperative fluid administration should be adjusted according to the intraoperative blood loss. Our findings endorse the utility of aVBFI and adjVFBI as valuable tools in guiding fluid therapy within the framework of ERAS protocols. However, further multicenter randomized trials are needed to definitively determine the best fluid therapy regimen for patients undergoing RC.<\/jats:p>","DOI":"10.3390\/cancers17010102","type":"journal-article","created":{"date-parts":[[2024,12,31]],"date-time":"2024-12-31T07:34:19Z","timestamp":1735630459000},"page":"102","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Does the Administration of Intravenous Fluid Matter in the Context of the Incidence of Postoperative Complications After Radical Cystectomy?"],"prefix":"10.3390","volume":"17","author":[{"given":"Pawe\u0142","family":"Lipowski","sequence":"first","affiliation":[{"name":"Department of Urology and Andrology, Collegium Medicum, Nicolaus Copernicus University, M.
