Transperitoneal versus extraperitoneal laparoscopic radical prostatectomy: Experience of a single center

To analyze, in a consecutive study, the perioperative, postoperative, and functional results of the transperitoneal and extraperitoneal approaches for laparoscopic radical prostatectomy. A total of 160 patients underwent radical prostatectomy and were subdivided into two groups. Group 1 underwent the transperitoneal approach and group 2, the extraperitoneal approach. The preoperative parameters, age, prostate-specific antigen level, biopsy Gleason score, American Society of Anesthesiologists class, body mass index, and clinical stage, were considered. The perioperative parameters evaluated were the operative time, blood loss, blood transfusion, hospital stay, catheterization time, complications, histopathologic findings, TNM stage, Gleason score, prostate and tumor volumes, and functional results. The patients in both groups had comparable preoperative data. No differences were observed between the two groups in the intraoperative data, except for the mean operative time (179 ± 54.6 for group 1 versus 133.7 ± 27 minutes for group 2). Also, no differences were observed between the two groups in terms of the postoperative data. The proportion of complications was 21.25% in group 1 and 22.5% in group 2. We recorded symptomatic lymphocele requiring treatment with a drain or reoperation in 8 patients (10%) in group 2 and 0% in group 1 ( P
