Robot assisted partial nephrectomy: Single center our experiences

Abstract

Aim: In this study, we aimed to present the functional and oncologic results of robotic assisted partial nephrectomy (RAPN) in clinicalstage T1 tumors.Material and Methods: Fifteen patients who had undergone RAPN for T1a-b kidney tumor between July 2017 and January 2019were included in the study. The demographic data, mean operation time, estimated blood loss, duration of warm ischemia, length ofhospital stay and oncologic results were evaluated retrospectively.Results: Ten male and five female patients with a mean age of 55.4±7.6 (48-71) years were included in the study. A 4-port transperitoneal approach was applied to all the patients. Nine right and six left renal masses with a mean tm diameter of 2.8±0.4 (2.4-3.6)cm were operated. The mean operation time was 217 (185-250) minutes, the mean blood loss was 225.6 (180-265) cc. Bleedingrequiring transfusion was seen in one patient and a spontaneously resolved ileus was seen in another patient. Urethral stents wereplaced into two patients because the collector system was opened. 8 (53%) of renal masses were reported as renal cell carcinoma.Surgical margin positivity was identified in 2 (13%) of the patients. No local recurrence or distant metastasis was observed in any ofthe patients. None of the patients experienced incisional hernia and late complications.Conclusion: Robot-assisted partial nephrectomy is presently the gold standard treatment for patients with clinical stage T1 renaltumor. RAPN is an effective, safe and minimally invasive treatment modality in patients eligible for partial nephrectomy.
