OBJECTIVETo assess the feasibility and safety of robot-assisted laparoscopic radical prostatectomy (RLRP) in the treatment of prostate cancer.
METHODSUsing the da Vinci robot surgical system, we performed RLRP for 34 patients with localized prostate cancer and analyzed the intraoperative and follow-up data.
RESULTSThe procedures were performed successfully in all the patients, with the mean operation time of 198 min (range 135-340 min), average blood loss of 257 ml (range 50-700 ml), and 1 case of blood transfusion, but no postoperative complications. Three cases had positive surgical margins. Postoperative examination at 4 weeks showed PSA > 0.2 microg/L in 2 cases, suggestive of residual tumor, for which maximal androgen block therapy was administered. The other 32 patients were followed up for 3-10 (mean 7.5) months, during which the average level of serum tPSA remained < 0.2 microg/L. Urinary continence was found in 94% (32/34) and 97% (33/34) of the patients at 3 and 6 months, respectively, of whom 77% (26/34) and 88% (30/34) had no urinary leakage (0 pad per day).
CONCLUSIONRLRP, with its advantages of less perioperative blood loss, low rate of positive margin, and good urinary continence, is a safe and effective surgical option for the treatment of prostate cancer.
