Consent will be obtained from all participating men prior to surgery.\n\nThe trial will consist of recording EII data from:\n\n1. In vivo pelvic floor and peri-prostatic tissues remaining after the prostate has been resected\n2. Resected ex vivo prostate following extraction from the abdomen (in the OR)\n3. Resected ex vivo prostate when transferred to Pathology, post-RARP\n\nThe study team will also track post-surgical complications due to the study's technology (e.g., infection) and additional time required to deploy the study technology used to assess feasibility of clinical integration of the EII device. Post-RARP pathological assessment of margin tissues will be used to train and evaluate the study's classification schemes for identifying Positive Surgical Margin (PSMs).","Men with a diagnosis of prostate cancer who require surgery.",[27],{"type":28,"name":29,"description":30,"armGroupLabels":20,"otherNames":20},"DEVICE","custom device to demonstrate a significant difference in electrical impedance signatures","Custom device will be used to measure electrical impedance signatures.",[32],{"name":33,"affiliation":34,"role":35},"Ryan J Halter, PhD","Dartmouth-Hitchcock, Manchester","PRINCIPAL_INVESTIGATOR",[37,41],{"name":33,"role":38,"phone":39,"phoneExt":20,"email":40},"CONTACT","(603) 646-0773","Ryan.J.Halter@dartmouth.edu",{"name":42,"role":38,"phone":43,"phoneExt":20,"email":44},"Kathy J Phipps, BA","603 646-5793","kathy.j.phipps@dartmouth.edu",[46],{"facility":5,"status":47,"city":48,"state":49,"zip":50,"country":51,"countryCode":52,"cosmosGeoPoint":53,"geoPoint":58,"contacts":59},"RECRUITING","Lebanon","New Hampshire","03756","United States","US",{"type":54,"coordinates":55},"Point",[56,57],-72.25176,43.64229,{"lat":57,"lon":56},[60,64],{"name":61,"role":38,"phone":62,"phoneExt":20,"email":63},"Lawrence M Dagrosa, MD","603-650-8123","Lawrence.M.Dagrosa@hitchcock.org",{"name":65,"role":66,"phone":20,"phoneExt":20,"email":20},"Einar Sverrisson, MD","SUB_INVESTIGATOR",{"type":68,"investigatorFullName":69,"investigatorTitle":70,"investigatorAffiliation":5,"oldNameTitle":20,"oldOrganization":20},"SPONSOR_INVESTIGATOR","Ryan J.
