Incidence, Risk Factors and Management of Symptomatic Lymphoceles after Radical Retropubic Prostatectomy

Area of Science:

• Urology
• Surgical Oncology
• Medical Complications

Background:

• Radical retropubic prostatectomy with pelvic lymph node dissection can lead to symptomatic lymphoceles.
• Understanding the incidence, clinical course, and risk factors is crucial for patient management.

Purpose of the Study:

• To investigate the incidence, clinical course, and risk factors for symptomatic lymphoceles after prostatectomy.
• To explore parameters predicting the failure of percutaneous lymphocele drainage.

Main Methods:

• Retrospective analysis of 599 patients undergoing radical retropubic prostatectomy with pelvic lymph node dissection (2008-2013).
• Correlation of lymphocele occurrence with clinical and histopathological parameters.
• Logistic regression analysis to identify independent predictors for lymphocele development and drainage failure.

Main Results:

• Symptomatic lymphoceles developed in 5% of patients, with a median diagnosis time of 22.5 days.
• Independent predictors for symptomatic lymphoceles included age > 67 years and removal of > 10 lymph nodes.
• Percutaneous drainage failure was associated with BMI > 27 kg/m² and drainage volume > 375 ml within 24 hours.

Conclusions:

• Approximately 1 in 20 patients develop symptomatic lymphoceles after this procedure.
• The number of lymph nodes removed is an independent risk factor for lymphocele development.
• High BMI and early high drainage volume are associated with percutaneous drainage failure, suggesting potential need for surgical intervention.
