What
retroperitoneal abscess?
The most common source of retroperitoneal abscesses are secondary with renal infections accounting for nearly 50% of all cases.
The posterior cul-de-sac is found between the uterus and the rectum. They are also called the excavatio recto-uterina (posterior) and excavatio vesico-uterina (anterior). Another term for cul-de-sacs is pouch of Douglas, named after the Scottish anatomist James Douglas.
