Treatment is sometimes required for symptomatic pelvic lymphoceles. We assessed the efficacy of percutaneous catheter drainage alone for pelvic lymphoceles. Sixteen symptomatic lymphoceles in 13 patients were treated by percutaneous catheter drainage without sclerotherapy between May 2006 and September 2009. All lymphoceles developed after radical pelvic lymphadenectomy for gynecologic malignant tumor. Technical success rate was 100% and clinical success rate was 85%. Two recurrences (15%) occurred in non-infected cases. No recurrence was observed in infected cases. Mean duration of catheter drainage was 11.6 days (range, 3∼28 days), and mean volume of drainage at catheter removal was 18.4ml/day(range, 0∼70ml/day). No major complications were encountered. Percutaneous catheter drainage alone seems to be a safe and effective procedure for pelvic lymphoceles, especially in infected cases.
