PurposeLaparoscopic partial nephrectomy is an advanced surgical procedure requiring technical skill in minimally invasive techniques. Tumors located adjacent to the renal hilum pose an additional challenge. We report a multi-institutional study of robotic partial nephrectomy for renal hilar tumors and describe our results.Materials and MethodsWe evaluated patients from 2 institutions who underwent robotic partial nephrectomy for renal hilar tumors. Renal hilar tumors were defined as tumors abutting the renal artery and/or renal vein on preoperative imaging. After clamping the renal hilar vessels tumors were excised with fine dissection from the renal vessels followed by sutured renal reconstruction.ResultsRobotic partial nephrectomy was successfully performed on 11 patients (mean age 56.4 years, range 30 to 76). Mean tumor size was 3.8 cm (range 2.3 to 6.4). Mean warm ischemia time was 28.9 minutes (range 20 to 39) and mean operating time was 202 minutes (range 154 to 253). Mean blood loss was 220 ml (range 50 to 750). Mean hospital stay was 2.6 days (range 1 to 4). Histopathological evaluation confirmed 8 cases of clear cell renal cell carcinoma, 1 of papillary renal cell carcinoma and 2 of chromophobe renal cell carcinoma. Surgical margins were negative for malignancy in all cases.ConclusionsRobotic partial nephrectomy is a safe and feasible approach for select patients with renal hilar tumors. Robotic assistance may facilitate tumor resection and renal reconstruction for challenging renal hilar tumors, offering a minimally invasive and nephron sparing surgical option for select patients who might otherwise require open surgery or total nephrectomy.
