Mapping Recovery, Quality of Life, and Physical Function After Partial and Radical Nephrectomy

October 30, 2026 updated by: Marie Juul-Haslund, Herlev and Gentofte Hospital

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in quality of recovery from enrollment to outpatient follow-up 21 days after surgery
Time Frame: From enrollment to the end of 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.
From enrollment to the end of follow up 21 days after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Quality of Recovery at other predefined time points.
Time Frame: Multiple times from enrollment to outpatient follow-up at 21 days after surgery

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.
Multiple times from enrollment to outpatient follow-up at 21 days after surgery
Change in quality of life assessed using the EQ-5D-5L
Time Frame: From enrollment to the end of follow up 21 days after surgery

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.
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.
Time Frame: From enrollment to the end of follow up, 21 days after surgery

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.
From enrollment to the end of follow up, 21 days after surgery
Validation parameters for the Quality of Recovery-15.
Time Frame: From enrollment to the end of follow up, 21 days after surgery

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.
From enrollment to the end of follow up, 21 days after surgery

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 22, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
