Preoperative Nutritional Risk Assessment for Predicting Complications after Radical Cystectomy plus Urinary Diversion...

Area of Science:

• Urology
• Surgical Oncology
• Nutritional Science

Background:

• Radical cystectomy with urinary diversion is a major surgery for bladder cancer.
• Postoperative complications can significantly impact patient recovery and outcomes.
• Preoperative nutritional status is increasingly recognized as a factor influencing surgical outcomes.

Purpose of the Study:

• To evaluate the predictive capability of preoperative nutritional risk assessment for complications following radical cystectomy and urinary diversion in bladder cancer patients.
• To determine if the Nutritional Risk Screening 2002 (NRS-2002) score can identify patients at higher risk of postoperative complications.

Main Methods:

• Retrospective analysis of 178 bladder cancer patients undergoing radical cystectomy plus urinary diversion.
• Assessment of postoperative complications within 90 days.
• Comparison of complication rates between patients with and without nutritional risk (NRS-2002 score ≥3 vs. <3).
• Logistic regression analysis to identify independent risk factors.

Main Results:

• Patients with nutritional risk (NRS-2002 ≥3) had higher rates of diabetes mellitus, longer operative times, and extended hospital stays compared to those without risk.
• Lower preoperative albumin (ALB) levels were observed in the nutritional risk group.
• Multifactorial analysis identified low preoperative ALB and high NRS-2002 score as independent risk factors for postoperative complications (P < 0.05).

Conclusions:

• The NRS-2002 score demonstrates good predictive value for postoperative complications in bladder cancer patients.
• Preoperative nutritional risk assessment provides a scientific basis for implementing targeted perioperative nutritional support.
• Early identification of at-risk patients can potentially mitigate surgical complications.
