    Abstract:
    PURPOSE: To retrospectively evaluate the short-term outcomes of lymphangiography and lymphatic embolization in the treatment of pelvic lymphocele after radical prostatectomy in patients with prostate cancer. MATERIALS AND METHODS: The data of nine, consecutive patients who underwent lymphangiography and lymphatic embolization for pelvic lymphocele after radical prostatectomy with pelvic lymph node dissection (PLND) between January 2016 and May 2018, were retrospectively reviewed. Lymphangiography was performed through inguinal lymph nodes in order to identify the lymphatic leakage. When a leakage was found, lymphatic embolization was performed using a directly punctured fine needle at the closest upstream lymph node or lymphopseudoaneurysm and with N-butyl cyanoacrylate glue. RESULTS: Lymphangiography demonstrated extravasation and/or lymphopseudoaneurysm in all of these patients. A total of 13 sessions of lymphangiography and lymphatic embolization were performed. The median number of lymphangiography and lymphatic embolizations required to achieve clinical success was one (range, 1-3). Three patients underwent repeated embolization with successful results. The technical and clinical success rates were 100%, respectively. The median time to resolution was 7 days (range, 2-19 days). There was no recurrence and no procedure-related complications during the follow-up period (mean, 26 weeks; range, 8-77 weeks) in all patients. CONCLUSIONS: Lymphangiography and lymphatic embolization are safe and effective for the management of pelvic lymphoceles after radical prostatectomy with PLND.
