The purpose of this study is to compare to assess the incidence of post-operative complications related to nephrectomy, which occur up to 1 month after the operation.

This is an observational, prospective, open, non-comparative (single arm), single-centre study.

The study population consisted of adult patients diagnosed with localised kidney cancer and scheduled for outpatient partial or total laparoscopic nephrectomy.

Patients eligible for outpatient surgery will be identified during the initial consultation with the urological surgeon. When the indication for surgery has been validated at the multidisciplinary consultation meeting and is planned to be performed as an outpatient procedure, the study will be proposed to the patient by the investigator during the preoperative consultation.

• Patients over 18 ;
• Localised kidney cancer ;
• Validation of curative treatment at a multidisciplinary consultation meeting;
• Partial or total laparoscopic nephrectomy scheduled on an outpatient basis;
• Membership of a social security scheme or receiving State Medical Aid;
• Patient able to understand the information relating to the study, to read the information leaflet and who has given his/her oral non-objection.

Exclusion Criteria:

• Emergency intervention ;
• Patient not eligible for outpatient treatment;
• Long-term curative anti-coagulant treatment ;
• Resident more than 100km from the clinic;
• Home alone on the first night;
• Patient of protected age (under guardianship or curatorship, or deprived of liberty).
