Abstract
To analyze the outcomes of the first 100 patients undergoing robotic radical prostatectomy by a single surgical team.From August 2001 to May 2002, we performed robotic radical prostatectomy in 100 patients with localized prostate cancer. The mean age was 60 +/- 0.67 years (SEM), the body mass index 27.5 +/- 0.35, the preoperative prostate specific antigen concentration 7.2 +/- 0.86 ng/mL, and follow-up 5.5 +/- 0.24 months. Thirty-eight patients also underwent pelvic lymph node dissection. We used the da Vinci surgical system and a subperitoneal approach (the Vattikuti Institute Prostatectomy; VIP). This is a prospective outcomes analysis of these patients.The mean operating time was 195 +/- 5.0 minutes, and the mean blood loss was 149 +/- 11.8 mL. No patient required blood transfusion. The stages of the cancers were pT(2a) in 21, pT(2b) in 64, pT(3a) in 5, pT(3b) in 9, and pT(3b)N(1) in 1. The positive surgical margin rate was 15%. At 1, 3, and 6 months, the continence rates were 37%, 72%, and 92%, respectively, and the potency rates were 11%, 32%, and 59%.The VIP is a safe operation with excellent operative parameters, low morbidity, and good surgical margins. The early functional results are promising.
