Why the study?
Preoperative dehydration is found in 30-50% of surgical patients, but its incidence in the urologic population was unknown.
Does preoperative dehydration affect postoperative outcomes and plasma creatinine levels in patients undergoing major abdominal urological surgery?
Population
187 patients scheduled for major abdominal urological surgery
Comparison
Dehydrated vs non-dehydrated patients assessed by the fluid retention index
Design
Single-center prospective cohort study

Preoperative dehydration may delay bowel recovery and raise early creatinine; leaves open whether rehydration improves outcomes in urological surgery.
Does preoperative dehydration affect postoperative outcomes and plasma creatinine levels in patients undergoing major abdominal urological surgery?
Preoperative dehydration affects approximately one-fifth of patients undergoing major urological surgery and is associated with delayed return of gastrointestinal function and early postoperative elevations in plasma creatinine.
