[CLINICAL OUTCOMES FOLLOWING ROBOT-ASSISTED PARTIAL NEPHRECTOMY (RAPN)].
2021
BACKGROUND Partial nephrectomy is the gold standard treatment for renal tumors less than 7 cm. OBJECTIVES To describe surgical techniques and trends of treating renal tumors less than 7 cm at our department and present the clinical outcomes of our experience with Robot-Assisted Partial Nephrectomy (RAPN). METHODS Out of an established prospective RAPN database, we retrieved demographic, clinical, surgical and pathological parameters. Operation length was defined as the time between the first surgical incision and the last suture (skin to skin). Warm ischemia time (WIT) was defined as the time between the renal artery clamping and clamp releasing. Data is presented as mean (range, standard deviation) or numeric value (%). RESULTS Overall, 250 RAPN cases were recorded between the years 2013-2020. Mean tumor size was 32 mm. Mean operation length was 153 minutes. Mean warm ischemia time was 17.5 minutes. Intra-operative complication rates, including converting the surgery to an open approach or to radical nephrectomy, was low. Mean estimated blood loss was 359 cc. An increase in the utilization of the robotic approach has been recorded throughout the years, with a concurrent decrease in the open and laparoscopic approaches. CONCLUSIONS RAPN is associated with lower complication rates and superior perioperative outcomes, therefore considered a good alternative to the open and laparoscopic approaches. Thus, RAPN is the gold standard treatment for renal tumors less than 7 cm at our institute.
