Objective. To investigate the results of robot-assisted partial nephrectomy (RAPN). Subjects and methods. 28 patients with clinically localized stage T1 renal cancer underwent RAPN in two urology clinics in 2005 to January of 2016. Computed tomography was carried out to determine the size and location of the tumor and the nature of its growth in all the patients. The RENAL nephrometry scoring system was employed to assess kidney tumor resectability. Results. Complications were graded according to the Clavien-Dindo classification. Grade III complications were observed in 2 (7%) patients. The median tumor size was 2.9±0.4 cm. Stages Т1а and T1b were established in 26 (93%) and 2 (7%) patients, respectively. The RENAL nephrometry system categorized resectability as low, moderate, and high complexity in 6 (21.4%), 18 (64.3%), and 4 (14.3%) patients, respectively. The mean duration of surgery was 134±35.2 (range 84—2060) minutes. The time of thermal ischemia of the kidney was 15.9±5.3 (range 0—22) minutes. The mean intraoperative blood loss was 302.2±121.8 (range 100—45) ml. The mean duration of hospitalization was 6.5 days. Morphological examination in all the patients operated on revealed renal cell cancer; positive surgical margins were not diagnosed in any of the morphological materials. A local tumor recurrence was found in one patient during a median follow-up period of 42.8 (range 8—125) months. Distant metastases were detected in none of the cases. Conclusion. RAPN for clinically localized renal cancer is a safe minimally invasive treatment with good immediate and long-term results.
