Conventional laparoscopic partial nephrectomy can be technically challenging [3, 4]. The advent of robotic assistance allowed the spread of the minimally invasive approach. Robotic-assisted partial nephrectomy (RALPN) is currently considered the gold standard minimally invasive approach for PN by many experts in the field. In the last decade, France witnessed a nationwide increase in the Da Vinci™ (Intuitive Surgical™, Sunnyvale, CA, USA) robotic system implementations (n = 174) both in public and private institutions. Given this evolving landscape, we aimed to assess the national evolution of renal surgery practices after the introduction of the robotic-assisted surgery. Renal surgery procedures data from 2009 and 2015 were obtained by querying the database of the Agence technique de l’information sur l’hospitalisation (ATIH) hosted by the French Health System.

Medical Procedures (CCAM) was used to extract data of partial nephrectomy (PN) versus radical nephrectomy (RN), open (OPN/ORN) versus laparoscopic (LPN/LRN)/robotassisted (RAPN) surgery. So far, a specific reimbursement coding for RAPN is not available. All minimally invasive PN were coded as LPN including the conventional LPN and RAPN. Da Vinci™ System being the unique device available, true conventional LPN was calculated as follows:

The International Classification of Disease (ICD-10) code C64 for kidney cancer was used to filter cancer-related procedures only. Since 2011, there are more than 9000 procedures performed yearly. There is a significant and continuous decrease of open surgery (tota
