Objective. To investigate the predictive value of preoperative nutritional risk assessment on the occurrence of complications after radical cystectomy plus urinary diversion for bladder cancer. Methods. Retrospective analysis of 178 patients with bladder cancer between July 2010 and March 2022 who underwent elective radical cystectomy plus urinary diversion was conducted. The occurrence of complications within 90 days after surgery was counted for all patients, and the postoperative complication rates of patients with and without nutritional risk were compared and analyzed. Also, logistic regression analysis was used to assess the relative risk coefficients of NRS-2002 and the occurrence of postoperative complications. Results. Comparison of clinicopathological characteristics and surgical conditions between the two groups showed that the proportion of combined diabetes mellitus, operative time, and postoperative hospital stay were higher in the nutritional risk group (NRS ≥3 score) than in the no nutritional risk group (NRS <3 score), while the preoperative blood albumin (ALB) level was lower than that in the no nutritional risk group (NRS <3 score). The results of multifactorial risk regression analysis showed that low preoperative ALB level and high NRS score were independent risk factors for postoperative complications in bladder cancer (). Conclusion. The NRS-2002 nutritional risk score has good predictive value for the incidence of postoperative complications in patients with bladder cancer and provides a scientific basis for perioperative nutritional support.

预测膀胱癌根治性膀胱切除加尿流改道术后并发症的术前营养风险评估


客观的。探讨术前营养风险评估对膀胱癌根治性膀胱切除加尿流改道术后并发症发生的预测价值。方法。对2010年7月至2022年3月期间接受择期根治性膀胱切除加尿流改道的178例膀胱癌患者进行回顾性分析。统计所有患者术后90 d内并发症的发生情况，比较有无营养风险患者的术后并发症发生率。此外，还使用逻辑回归分析来评估NRS-2002的相对风险系数和术后并发症的发生。结果。两组临床病理特征及手术情况比较显示，营养风险组（NRS≥3分）合并糖尿病的比例、手术时间、术后住院时间均高于无营养风险组（NRS< 3id=141> ）。结论。 NRS-2002营养风险评分对膀胱癌患者术后并发症的发生具有良好的预测价值，为围术期营养支持提供科学依据。
