This study aims to describe exclusively robot-assisted surgery as an alternative nephron-sparing approach for renal intraparenchymal tumors. Patients and Methods: We retrospectively analyzed all patients with completely endophytic tumors undergoing robot-assisted partial nephrectomy, treated under the Da Vinci System®, aided by intraoperative ultrasound. The patients¡¯ demographic characteristics, perioperative and oncological outcomes were assessed. Results: From a total of 13 partial nephrectomies performed between 06/2010 and 10/2021, all patients underwent nephrotomy. The patients¡¯ mean age was 52 years and the tumor measured mean 2.6 cm. Warm ischemia time was 24 minutes and histopathological analysis revealed that 12 patients had renal cell carcinoma. In a mean 36-month follow-up, no significant renal function alterations were found and no local or systemic recurrences occurred. Conclusion: Robot-assisted access is a safe and effective option for the nephron-sparing technique in completely intraparenchymal renal tumors. %K Robotic Surgical Procedures %K Kidney Neoplasms %K Organ Sparing Treatment %K Nephrectomy %K Renal Mass %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=128713
