An observational study in Nephrectomy / Methods and Nephrectomy, sponsored by Herlev and Gentofte Hospital. Recruiting at 1 site in Denmark. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-03.
Sponsored by Herlev and Gentofte Hospital · Observational
Aim:
To investigate recovery, quality of life, and physical function before and after partial or radical nephrectomy.
To validate the Quality of Recovery-15 (QoR-15) questionnaire in a urological cohort and investigate whether the questionnaire can be used to identify differences in patient-reported recovery across patient populations.
Herlev and Gentofte Hospital is the lead sponsor of 75 studies on the registry; 25 are open to participants now.
Counted across the registry records on this site, refreshed daily.
All patients >18 years scheduled for radical or partial nephrectomy
Inclusion criteria
None, observational study
Change in quality of recovery from enrollment to outpatient follow-up 21 days after surgery
Quality of recovery is evaluated with the danish translation of the verified questionnaire Quality of Recovery-15. It is a 15-item patient questionnaire, where the score ranges from 0-150. A higher score indicates better patient-reported quality of recovery. QoR-15 will be assessed preoperatively, and 1, 2, 7 and 21 days after surgery. Change in QoR-15 from enrollment to 21 days after surgery is the primary outcome measure. Change in QoR-15 at other assessment times will be assessed as secondary outcome measures.
Time frame: From enrollment to the end of follow up 21 days after surgery
Change in Quality of Recovery at other predefined time points.
Quality of recovery is measured by the danish translation of the verified questionnaire Quality of Recovery-15. It is a 15-item patient questionnaire, where the score ranges from 0-150. A higher score indicates better patient-reported quality of recovery. QoR-15 will be assessed at preoperatively, and 1, 2, 7 and 21 days after surgery.
Time frame: Multiple times from enrollment to outpatient follow-up at 21 days after surgery
Change in quality of life assessed using the EQ-5D-5L
Quality of life is evaluated with the danish translation of the validated questionnaire EQ-5D-5L. The questionnaire evalutes five health dimensions (mobility, self-care, usual acitivites, pain/discomfort, anxiety/depression) ranging from "no problems" to "unable/ extreme problems". Additionally, it includes a visual analog scale scoring from 0-100, reflecting the participants overall self-reported health state. A higher score indicates a better patient-reported quality of life. Quality of life will be assessed preoperatively and 21 days after surgery.
Time frame: From enrollment to the end of follow up 21 days after surgery
Physical function assessed using the 30 second sit to stand, handgrip strength and 6 minute walking test.
Physical function assessed using the 30 second sit to stand test (number of repetitions in 30s), handgrip strength test (maximum voluntary muscle strength in kg) and 6 minute walking test (distance in meters). The higher the test results, the better, for all tests. The tests are performed preoperatively and 21 days after surgery.
Time frame: From enrollment to the end of follow up, 21 days after surgery
Validation parameters for the Quality of Recovery-15.
An evaluation of validity, reliability, responsiveness and feasibility of the Quality of Recovery-15, assessed preoperatively, and 1, 2, 7 and 21 days after surgery.
Time frame: From enrollment to the end of follow up, 21 days after surgery
