The present study is an observational study designed to assess and compare clinical outcome and quality of life after nephron sparing treatment of small renal tumors.
Partial nephrectomy, where the tumor is being be surgically removed, has traditionally been the preferred nephron sparing treatment for small renal cell carcinomas (RCC). Cryoablation was introduced 20 years ago as a treatment option for patients with RCC with a high surgical risk. Previously, this group of patients had no available treatment. Cryoablation is a minimally invasive treatment that uses extreme cold to destroy the cancer. In recent years, indications for cryoablation of RCC has extended. Cryoablation is now offered as a curative treatment, also including patients without severe comorbidity.
Retrospective studies imply that patients with RCC have lower quality of life compared to other cancers and that choice of treatment and remaining healthy renal tissue have a correlation with quality of life. Knowledge about the patient perspective is crucial in relation to delivering the highest quality of care in the healthcare system. Exploring quality of life through patient reported outcome is one way of exploring the patient perspective.
In this prospective study the investigators aim to assess clinical outcome and quality of life after partial nephrectomy and cryoablation. Results are expected to generate evidence-based knowledge essential in treatment decisions for RCC globally.
The overall aim of this prospective study is to assess and compare clinical outcome and health related quality of life after partial nephrectomy and cryoablation of renal tumors at stadium T1 in adult patients. The specific objectives is:
All eligible patients will be offered inclusion. Patients will be allocated to treatment group based on shared decision making between the patient and the treating urologist and recommendation from a multidisciplinary team conference. This reflecting the clinical practice.

| Change from baseline in health-related Quality of life measured by the validated Danish version of The European Organisation for Research and Treatment of Cancer - Core Quality of Life Questionnaire (EORTC QLQ C-30) | EORTC QLQ C- 30 will be used for quality of life measurement. A scale range 0-100, a higher score indicating better quality of life within five functional scales ( physical, role, cognitive, emotional, and social), three symptom scales (fatigue, pain, and nausea and vomiting), a global health status scale and the following six single item symptom measures; dyspnea, insomnia, appetite loss, constipation, diarrhea, and functional difficulties. | Change from baseline at 14 days and 3 months postoperatively. |
| Change from baseline in health-related Quality of life (HRQoL) to 3 months after treatment measured by the validated Danish version of SF-12v2. | HRQoL will be assessed by the Short Form 12 version 2.0 (SF-12v2) Health Survey scores. | 3 months |
| Self evaluation of rehabilitation and experience of course of treatment measured by a locally validated questionnaire. | Patients' self evaluation of rehabilitation and course of treatment will be assessed by the locally validated rehabilitation questionnaire for renal cancer (RQRC). The questionnaire consists of seven items. Responses will be reported in percentages. | 3 months |

Patients are recruited from the Department of Urology at Odense University Hospital and Zealand University Hospital based in The Region of Southern Denmark and Region Zealand respectively. Odense University Hospital and Zealand University Hospital are the only centers offering nephron sparing treatment for renal cell carcinomas within the two regions.
The Region of Southern Denmark and Region Zealand are two out of the five regions in Denmark. They have a population of about 2 million people combined. The population of the regions are considered demographic comparable.
