Background Fast-track concepts reduced hospital stay from 15-20 days to three days for patients who underwent a colon resection [1-5]. A well-designed pilot study determined the efficacy of a fast-track program for a laparoscopic radical nephrectomy, and the fast-track group was discharged earlier from the recovery room median (74+/-23 v 103+/-47 minutes) as well as from the hospital median (41+/-11 v 59+/-11 hours) [6]. Implementation of the principles of the fast-track program shortened the postoperative hospital stay from eight to four days for patients who underwent an open radical nephrectomy [7]. Taek-Gu Lee et al. documented how early mobilization after colon surgery resulted in reduced recovery times without increased complications [8]. Laparoscopic surgery is minimal invasive with less surgical stress, morbidity and mortality [9]. The use of laparoscopic nephrectomy in Denmark reduces the hospital stay to 5.2 days which did not meet the foreign countries outcome [06].

Therefore a combination of the advantages of laparoscopic surgery and the fast-track concepts could be used by nephrectomies. However, no prospective studies describing the course after nephrectomies, where these advantages are exploited and it is important to make a basic study to describe and understand the factors of surgical outcome.

Aim of study To describe the postoperative period after laparoscopic trans-peritoneal nephrectomy that performed as an ambulatory procedure.

Method A prospective study will involve 62 patients who have been diagnosed with Cancer Renis DC649.

All patients will receive the results of CT-scanning at outpatient and of them who meet the inclusion criteria for the study will be informed about the study and will receive a written information according to appendix 1., and a new time with (NA) to get the results for kidney function and oral information about the study as well as their acceptation to be connected to the study, those patients will receive a standard recommendation to be discharged from hospital on the day of their operation and they will restart their normal activities the day after the operation unless there are preventing factors. All patients will be thoroughly informed by the examiner how to complete the questionnaire and will come through different tests according to appendix 2., a blood test will be taken according to appendix 12.

All patients should have a CT-scanning of abdomen, chest X-ray and kidney function test before the operations.

Statistic The number of patients, have been decided to be included to each study, is based on the realized number of nephrectomy operations that can be done during the specified period within each department and not on the statistic power of study.

The Scheffé's test will be used for multiple comparisons. The correlation between variables will be evaluated by using the Spearman's rank correlation coefficient. P values less than 0.05 is considered significant. Statistical analyses will be performed by SPSS statistic program software.

Publications The results of each study, irrespective of whether these are positive or negative, will be published in international scientific journals and will be distributed at relative conferences. The published articles will have Azawi NH as first author, Christensen T as last author and co-authors according to Vancouver rules.

Ethics The study will be reported to the Danish National Committee on Biomedical Research Ethics and regionsjaelland paraplygodtkendelsen data control, Ph.D. student (NA) will apply for enrollment to the PhD programme at the University of Copenhagen. Consent forms will be received from all patients and they will receive written information about project. The project will protect all of the data gathered.
