[Hemostasis of the preprostatic veins in total cystoprostatectomy. Anatomical bases]. / Hémostase des veines préprostatiques dans la cystoprostatectomie totale. Bases anatomiques.

ABSTRACT

An anatomical study has enabled the authors to propose a diagrammatic description of pre-prostatic veins, the haemostasis of which is one of the difficult stages in total cystoprostatectomy for cancer. These veins are surrounded by the pubovesical ligaments but they are separated from the membranous urethra by a cleavage plane which can be used to control venous bleeding.
