|Dehydration Postoperative Nausea and Vomiting Postoperative Complications|
The information about the impact of preoperative dehydration on postoperative outcome is conflicting. One of the reported difficulties of the studies in this field is to get adequate power for statistical significance. The incidence of preoperative dehydration in different surgical populations has been reported in about one third of patients. The prevalence in the urologic population is not known.
This is a monocentric observational study with no study intervention. The goal is to consecutively include all patients undergoing major urologic surgery during 365 days who meet the inclusion criteria to assess the prevalence of preoperative dehydration in elective major abdominal urologic surgery when the standard operation procedures of the University Hospital Bern are applied.

- Prevalence of Dehydration at Induction of Anesthesia [ Time Frame: Time point 0: time (estimated between 7am and 4pm on day of surgery) at Induction of Anesthesia for Major Urologic Surgery ]Number of dehydrated patients judged by urine specific gravity, osmolality, creatinine, color.
- Postoperative Nausea and Vomiting (PONV) [ Time Frame: 6 hours, 24 hours and 48 hours postoperatively ]Number of patients with postoperative nausea and/or vomiting at 6, 24 and 48 hours postoperatively.
- Gastrointestinal function (flatus/defecation) postoperatively [ Time Frame: 24 hours and 48 hours postoperatively ]Time of first flatus or defecation
- Renal function postoperatively [ Time Frame: 6 hours, 24 hours and 48 hours postoperatively ]Creatinine 6, 24 and 48 hours postoperatively.
- Fluid balance [ Time Frame: within 24 hours postoperatively ]Judged by administered and lost fluids intraoperatively and by weight balance on POD 1.
- Complications within hospitalization [ Time Frame: within hospital stay, expected to be within 2 weeks postoperatively ]Number of complications according to a prospective list
- Quality of recovery [ Time Frame: 24 hours postoperatively ]Changes in Quality of Recovery using the validated 15 items quality of recovery (QoR-15) score : QoR is a patient reported outcome short questionnaire that measure the quality of recovery after surgery and anaesthesia. It incorporates 5 dimensions of health (patient support, comfort, emotions, physical independence, pain). This is a shortened validated version of the QoR 40 including 15 items. QoR-15, with a score range from 0 to 150 (0 worst possible, 150 best possible), is easy to perform. Recently a meta-analysis showed that QoR 15 fulfils requirements for outcome measurement instruments.
