GLOBAL RENAL MASS STUDY – A PROSPECTIVE INTERNATIONAL STUDY ON INDICATIONS, TREATMENT MODALITIES AND OUTCOMES.

Over the last 10 years, we have witnessed an increasing interest in the management of Renal masses. Three main reasons are responsible for this: the increasing diagnostic incidence which leads to the incidental discovery of small renal masses, the development and consolidation of partial nephrectomy and minimal invasive surgical treatments, the latter including both a laparoscopic approach and ablation techniques, and the increasing trend to nephron sparing surgery.

However, there are some fundamental differences concerning the indications for surgery and the technique used, mainly based on experience and institutional characteristics. Those factors may modulate outcomes. Similarly, specific patient and technical factors may influence treatment related morbidity.



In this prospective study we aim to assess on a global basis the indications for treatment and modality and outcomes of surgical treatment for renal masses including (laparoscopic/robotic) radical or partial nephrectomy and (percutaneous/laparoscopic assisted) ablative treatments. Each centre participating in this project will include during a one-year period all the patients treated at their site, with a diagnosis of a renal tumour or candidates for active surveillance (AS).

To assess the current patterns of surgical or instrumental treatment and indications for RCC treatment.

One year inclusion of all data. Data will be collected prospectively. Variables will include preoperative assessment, operative data, histological results and postoperative period until 30 days.
