[Surgical and pathological consequences of preoperative immunotherapy in onco-urology].

Introduction: Patients treated with immunotherapy might need surgical procedures in addition to the medical treatment. The main indications are cytoreductive nephrectomy, cystectomy (as part of clinical trials) and metastasis removal in some oligometastatic patients. This study aims to assess the feasibility of surgery for patients treated by immunotherapy and describes the histological modifications found in the pathological analysis.
