Patients were grouped according to the operative approach: G1 included 15 patients, receiving LUC (<jats:italic>n<\/jats:italic>\u2009=\u20099) and RALUC (<jats:italic>n<\/jats:italic>\u2009=\u20096), and G2 included 115 patients, receiving LP (<jats:italic>n<\/jats:italic>\u2009=\u200930) and RALP (<jats:italic>n<\/jats:italic>\u2009=\u200985).
