Background: Robotic partial nephrectomy (RPN) is a rapidly growing treatment for small renal mass (SRM). In fact, RPN has shown good functional and oncologic outcome. In this manuscript, we are reporting on the incidence and pattern of recurrence of renal cell carcinoma (RCC) treated with RPN. Patients and Methods: We reviewed prospectively collected data of patients who underwent RPN between September 2009 and March 2018. We selected patients with final pathologic diagnosis of RCC after the resection of their SRM. We described the incidence and pattern of recurrence in the patients who had it. Results: A total of 335 patients with SRM underwent RPN. We found 269 patients to have RCC on the final pathologic evaluation of the SRM. Eight cases of recurrence were found with a recurrence rate of 2.9% after the mean follow-up period of 31 months (range 18–72). The pattern of recurrence presented as follows: two patients (0.7%) had trocar site recurrence (TSR), one patient (0.37%) had locoregional recurrence, and three patients (1.1%) had recurrence of the disease at the resection bed. Two patients (0.7%) developed second primary tumor in the other kidney. No cancer-related mortality occurred during the follow-up period. Conclusion: TSR, locoregional recurrence, tumor bed recurrence, and contralateral tumor development are observed patterns of RCC recurrence after RPN. Recurrence was seen in up to 72 months. RPN provides great cancer control and high cure rate when utilized to treat RCC presenting as SRM.
