title: Laparoscopic pelvic lymphnodes dissection for prostate and bladder cancer: indication, techniques and results.
abstract: Laparoscopic pelvic lymphadenectomy has been proposed for staging of prostate cancer and it might be used, in selected cases, also in bladder cancer. On a total of 31 laparoscopic lymphadenectomies (LPND), 18 for prostate cancer and 13 for bladder cancer, we found positive nodes in 8 cases (26.1%), 4 in prostate and 4 in bladder cancer group. We had no intraoperative complications and negligible postoperative complications (in 10% of cases shoulder-tip pain and in 24% subcutaneous emphysema); all these spontaneously disappeared after 24-36 hours. Patients with negative nodes underwent radical surgery except two prostate cancer patients who underwent radiotherapy, and patients with positive nodes underwent hormonal therapy (for prostate cancer) or chemoradiotherapy protocol (for bladder cancer). In conclusion, laparoscopic lymphadenectomy proved to be a feasible and safe method for staging urological malignancies, being less invasive, with shorter hospitalization and postoperative convalescence than open lymphadenectomy. It should be mainly indicated in high risk prostate cancer patients (elevated PSA and/or Gleason score). In bladder cancer patients, it could be proposed in bladder sparing investigational protocols, as the percentage of pelvic nodes metastases in T2/T3 bladder cancer is sufficiently high to justify an additional staging procedure.
