A., MORESELLI, S., ET AL., 2020). THE AIM OF THE STUDY WAS TO PRESENT THE SURGICAL TECHNIQUES AND THE POSTOPERATIVE OUTCOMES IN WOMEN TREATED WITH ROBOTIC EXCISION FOR DEEP ENDOMETRIOSIS INVOLVING THE URINARY TRACT. THIS STUDY RETROSPECTIVELY REVIEWED THE PROSPECTIVELY RECORDED CLINICAL DATA OF WOMEN CONSECUTIVELY UNDERGOING MINIMALLY INVASIVE TREATMENT FOR COMPLEX ENDOMETRIOSIS INVOLVING URINARY TRACT IN OUR CENTER BETWEEN JANUARY 2012 AND JUNE 2018. A TOTAL OF 74 CONSECUTIVE PATIENTS WERE ENROLLED AND, OF WHICH, 46 WERE TREATED WITH ROBOTIC SURGERY WITH EITHER A DA VINCI SI OR XI DA VINCI SURGICAL SYSTEM. ALL THE PATIENTS RECEIVED A PREOPERATIVE MULTIDISCIPLINARY EVALUATION WITH THE GENERAL SURGEON, THE GYNECOLOGIST, AND THE UROLOGIST DUE TO THE FREQUENT CONCOMITANT INVOLVEMENT OF BOWEL AND GENITAL SYSTEM. PATIENTS UNDERGOING ROBOTIC SURGERY WERE TREATED WITH THE SI OR XI DA VINCI SURGICAL SYSTEM. WITHIN THE JOURNAL A
