Abstract：Objective:To demonstrate the clinical experience with laparoscopic pelvic lymph node dissection for 41 prostate cancer patients.Methods:Between March 2009 and December 2012,the clinical data of 41 consecutive patients treated with laparoscopic radical prostatectomy and pelvic lymph node dissection by a single surgeon were analyzed retrospectively.All patients were divided into two groups according to preoperative PSA,Gleason score and clinical stage.The lymph node-positive ratio was compared between two groups statistically.Results:The average operative time was (35.0±5.8) min.The average estimated bleeding volume during lymphadenectomy was (42.7±19.9) mL.The average number of lymph nodes dissected was (6.9±1.8).The lymph node-positive ratio in PSA>20 μg/L group and Gleason score >7 group was 23.7% and 20.0% respectively,which was higher than in low-risk control group significantly.26.8% (11 cases) of patients had drainage more than 7 days.Conclusions:The lymph node-positive ratio was higher in high-risk clinically organ confined prostate cancer patients.Laparoscopic pelvic lymph node dissection was recommended to perform in those patients together with radical prostatectomy.
