INTRODUCTION: In this study, we aimed to evaluate surgical, functional and oncolojical outcomes of robotic partial nephrectomy in patients with cT1 renal tumors. METHODS: Between August 2008 and May 2013, 45 patients with c T1a-b renal tumors underwent robotic partial nephrectomy (RPN) were included in this study. Patients’ demographics, mean operative time, estimated blood loss, warm ischemia time, hospital stay, complications, oncologic outcomes were evaluated retrospectively. Statistical analyses were done using with SPSS Statistics v.20 (IBM, Armonk, NY, USA) software. RESULTS: Mean age of the patients, tumor size and R.E.N.A.L nephrometry scores were 55±11 years, 3.56±1,3 cm and 5.36±1.55 (range=4-10), respectively. All patients underwent 4 or 5 port robotic partial nephrectomy via transperitoneal approach. The mean operation time and estimated blood loss were 133±45 min and 210±130 ml (range, 50-2100 ml), respectively. Warm ischemia time was 23.5±8,4 min. Drain removal time was 3,2±1 days after surgery. Length of hospital stay was 4.3±1.5 days (range, 2-8 days). No complications occurred intraoperatively. Eight patients had Clavien grade 1 or 2 postoperative complications. Thirty-seven tumors (82.2 %) were malignant as indicated in final pathology reports of the resected 45 tumors. Surgical margin was positive in one patient. However, there were any local recurrence during an average of 25 month-follow-up period. DISCUSSION AND CONCLUSION: Partial nephrectomy is the current gold standart treatment modality in patient with c T1 renal tumors. RPN is an effective and reliable treatment alternative in patients who are amenable to nephron sparing surgery.
