Summary

This study tests whether giving patients a special nutritional drink (immunonutrition) before bladder removal surgery can reduce complications like infections. About 232 adults having open cystectomy for various bladder conditions will be randomly assigned to receive the drink or standard care. The main goal is to see if the drink lowers infection rates within 30 days after surgery.
