Robot-assisted partial nephrectomy depending on the complexity of the anatomical location of tumor
The article is about comparative analysis of the implementation of robot-assisted partial nephrectomy (RARP) in patients with localized tumor (stage T1), depending on its anatomical location. Patients were divided into two comparable groups: the 1st group(n-22) - RARP in patients with different tumor localization, 2-nd group(n-6) - RARP in patients with tumor localized on the posterior surface in the upper segment of the kidney. To assess the resectability of the tumor of the kidney, as well as a detailed analysis of the anatomical features, we use the system of indicators R. E. N. A. L. Statistical analysis was conducted on major intra/post-operative parameters: average operation time, ischemia time of the kidney, volume of blood loss, degree of postoperative complications. Robot-assisted partial nephrectomy is a safe and effective surgery for her tumor lesions in stage T1. Application scale R. E. N. A. L, in most cases, allowed us to assess anatomical characteristics of the tumor, to determine the technical possibility of resectability and complication of partial nephrectomy. The results of RARP in patients with tumor localized on the posterior surface in the upper segment of the kidney, showed a significant association with increase in mean operation time, time of ischemia of the kidney, volume of blood loss, presence of complications, compared to classifying the way to use index (R. E. N. A. L).
