Nutrition for cystectomy with pelvic lymph nodes dissection: perioperative considerations.

Assessment of nutritional status by an objective measure such as NRS-2002 or sarcopenia in the preoperative workup of major abdominal surgeries helps identify patients at risk for increased surgical morbidity and mortality. Preoperative and immediate postoperative nutritional supplements have demonstrated to decrease risk of complications and length of stay. Enhancing the immune system with immunonutrition has also been suggested as major player in this setting. In this review on nutritional considerations in the perioperative setting of radical cystectomy, we will describe several tools available to improve the complications rates and mortality surrounding this procedure.
