Robotic-assisted laparoscopic partial nephrectomy. Retrospective descriptive study over a 10-year period. Anesthetic experience

Robot-assisted laparoscopic surgery is currently the surgical treatment of choice for small renal masses. Objective: Reviewing the anesthetic management and perioperative morbidity of patients undergoing robotic-assisted laparoscopic partial nephrectomy (RALPN) from 2009 to 2019 at Hospital Universitario Donostia. Material and methods: Retrospective, descriptive, observational study involving 343 patients. Results: 95 % of the patients were ASA II-III. Transient renal artery clamping was performed in 91 %, with a mean ischemia time of 17.79 minutes. The mean duration of the procedure under balanced general anesthesia was 184 min. Standard monitoring was performed along with invasive arterial pressure monitoring (IAP), central venous catheter (CVC) and EV1000 platform (Edwards®) for complex patients. Complications were recorded in 40 patients (11.67 %). Patients under anti-aggregation therapy experienced more bleeding than non-anti-aggregation patients (p 0.04) but did not require more transfusions. Patients with a higher anesthetic risk did not experience more complications. No statistically significant association was found between worsening renal function and the occurrence of intraoperative complications. 21 patients (6 %) were readmitted due to complications; the most frequent complication was renal artery pseudoaneurysm that required endovascular embolization. Conclusions: It should be highlighted that after ten years of experience with this technique, the patients with a higher anesthetic risk have not experienced serious perioperative complications. RALPN is a safe technique that demands a careful anesthetic support. A robot-assisted approach alone is not a guarantee for success without strong teamwork.
