The occurrence of intraoperative complications during partial nephrectomy and their impact on postoperative outcome: results from the RECORd1 project

BACKGROUND: The aim ofthis study was to analyze the predictive factors ofintraoperative complications in patients submitted to PN and the impact ofintraoperative complications on postoperative outcomes. METHODS: Data of 1055 patients who underwent PN for cortical renal masses were recorded from a multicenter prospective observational study (RECORd l project). RESULTS: Overall, 48 (5%) patients experienced 49 intraoperative complications (four medicaI, 45 surgical). At multivariable analysis, age (OR=1.02, 95% CI: 1.00-1.08, P=0.03), imperative versus elective surgical indication (OR=2.55, 95% CI: 1.12-5.85, P=O.03), open (OR=5.76, 95% CI: 1.05-9.21 , P=O.OI) and laparoscopic (OR=2.35, 95% CI: 1.11- 4.95, P=0.03) versus robotic approaches resulted independent predictive factors of intraoperative complications. Patients experiencing intraoperative complications had a significantly higher rate of overall postoperative complications (41 .6% vs. 17.3%, P
