Treatment Outcomes in Patients With Symptomatic Lymphoceles Following Radical Prostatectomy Depend Upon Size and Presence of Infection

Objective: To guide treatment decisions for symptomatic lymphoceles after radical prostatectomy. We examined our experience to create a treatment algorithm. Materials and Methods: We evaluated all patients that underwent radical prostatectomy at our institution from 2003 to 2012. Presenting signs, management and treatment outcomes were evaluated. Results: Of the 8081 patients who underwent radical prostatectomy from 2003 to 2012, we identified 123 (1.5%) patients who developed a symptomatic lymphocele, 70 sterile and 53 infected. Percutaneous aspiration was performed in 26 of 123 (21%) patients, of those, 100% recurred. A drain was placed in 86 of 123 (70%) patients for a median of 13 vs 33 days for the infected and sterile lymphocele groups, respectively (P <.001). The median duration of drainage for sterile lymphoceles was 15 vs 58 days for lymphoceles <10 cm vs ≥10 cm (P <.001). Percutaneous drainage was successful in 93% and 86% of patients with infected and sterile lymphoceles, respectively. Laparoscopic unroofing was performed in 18 sterile lymphocele patients (15%) with a success rate of 94%. Conclusion: Aspiration of symptomatic lymphoceles should be reserved for diagnostic purposes due to a high risk of recurrence. Infected lymphoceles are optimally treated with drain placement and antibiotics, and have excellent resolution rates. While sterile lymphoceles <10 cm can be successfully managed with drain placement, if drainage and sclerotherapy fail, laparoscopic unroofing should be considered. For patients with sterile lymphoceles ≥10 cm there should be a shared decision-making process to weigh the risk of a protracted course if a drain is utilized vs upfront laparoscopic unroofing.
