Real-Time Transrectal Ultrasound Guidance During Laparoscopic Radical Prostatectomy: Impact on Surgical Margins

摘要: Purpose: We evaluated whether intraoperative real-time TRUS navigation during LRP can decrease the incidence of positive surgical margins.Materials and Methods: Since March 2001, 294 patients with clinically organ confined prostate cancer undergoing have been retrospectively divided into 2 groups, including group 1—217 who underwent without from 2001 to February 2003 2—77 undergone since 2003. Various baseline parameters were similar between groups. Before senior surgeon had already performed more than 50 cases LRP, thus, gaining reasonable familiarity technique.Results: Compared 1, a significantly decreased rate margins in pT3 disease (57% vs 18%, p = 0.002). Positive margin rates also our overall experience (29% 9%, 0.0002). Intraoperative correctly predicted pT2 85% 86% patients, respectively. Of 54 v...
