Abstract
Pelvic lymphadenectomy and interstitial radiotherapy of the prostate for early carcinoma is a procedure with a significant postoperative morbidity, depending on the extent of dissection, type of drainage, and use of heparin. Hematoma and lymphocele formation seems to be promoted by heparin. Limited lymph node dissection, appropriate, drainage, and the abandonment of heparin for prophylaxis of thromboembolism can reduce the complications associated with pelvic lymphadenectomy.
