Objective:
To define the anatomical landmarks allowing precise vesiculectomy to be performed during radical prostatectomy for cancer.
Material And Methods:
12 non-formalin-preserved anatomical subjects were dissected as during retropubic and perineal prostatectomy, with and without coloured latex vascular injection.
Results:
Three anatomical landmarks were defined: 1) Denonvilliers' fascia; 2) vas deferens; 3) arteries supplying the seminal vesicles.
Conclusions:
These three anatomical landmarks ensure: complete resection, preservation of adjacent anatomical structures and elective haemostasis.
