Robotic Partial Nephrectomy in the Treatment of Renal Angiomyolipoma

Abstract Purpose: To present the experience and efficacy of Robotic Partial Nephrectomy (RPN) for the management of renal angiomyolipomas (AMLs) with regard to renal function preservation and perioperative outcomes. Patients and Methods: We retrospectively searched our RPN database for pathologically confirmed renal AML patients between 2006 and 2014. Clinical presentation, perioperative complications, and postoperative outcomes of the patients were analyzed. Preoperative imaging findings were reviewed to examine their ability to predict pathology of AML. Results: From 1005 RPN performed in our center during the study period, 53 patients met our inclusion criteria. The mean age at presentation was 54.1 (±13) years, and 42 (79.2%) patients were female. Median tumor size was 2.8 (interquartile range [IQR], 1.8–4.6) cm. The indication for RPN was suspicious radiologic features for malignancy in 42 (79.2%) patients and acute retroperitoneal hemorrhage risk and pain in 11 (20.8%) patients who were found to hav...
