Abstract

The role of laparoscopic pelvic lymphadenectomy was studied in located prostate cancer. Pelvic lymphadenectomy was performed in 230 patients with located prostate cancer before radical prostatectomy. Thirty-five and 195 patients underwent laparoscopic pelvic lymphadenectomy (LPL) and open pelvic lymphadenectomy (OPL), respectively. During surgery, lymph nodes were bilaterally removed in the area of the obstructed fossa and internal iliac veins. The duration of surgery in the LPL group was statistically significantly longer (p < 0.001) than that in the OPL group. During LPL, the volume of blood loss and the duration of postoperative lymphorhea were statistically significant lower than those in the OPL group (p < 0.001). Both group showed no statistically significant differences in the number of removed lymph nodes (p = 0.172). There was a statistically significant relationship between the stage T and the frequency of the stage N1 (p = 0.027) and between the Gleason scores and the frequency of the stage N1 (p = 0.001). Correlation analysis showed a weak correlation between the level of PSA and the stage N1 (r = 0.212). LPL has been shown to be a beneficial alternative to OLP and it is expedient to be primarily guided by the degree of tumor differentiation while selecting patients for pelvic lymphadenectomy
