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<sup>®</sup>, 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.展开更多

Material and Methods: observational, transversal and retrospective study, through analysis of records and lab exams of 146 patients undergoing nephrectomy from January 2015 to December 2018. Results: Statistically significant difference was found between etiology and patients’ age (p-value Conclusion: This study shows that a large number of young patients undergo nephrectomy, many times avoidable;within a benign disease context with an increased risk of developing renal failure. Greater attention from the public service is required to tackle such chronic condition and its complications.展开更多
