	MedlinePlus Medical Encyclopedia: Retroperitoneal fibrosis
		Retroperitoneal fibrosis is a disorder in which the tubes that carry urine from the kidneys to the bladder are blocked by a fibrous mass in the back of the abdomen.
		Retroperitoneal fibrosis is a rare disorder caused by an excess of fibrous tissue in the area just behind the stomach.
		It is most common in people aged 40 - 60, and men are twice as likely to develop them as women.

		In 176, the diagnosis was made at celiotomy; in 67, retroperitoneal hematoma had ruptured into the abdomen and all were explored; the retroperitoneal hematoma was not disturbed in 62 because it appeared contained and not expanding.
		Retroperitoneal hematomas in patients who are in shock, who have peritoneal irritation or positive peritoneal lavage results, should undergo operation.
		Those retroperitoneal hematomas found to be contained Á and not expanding should not be opened, unless it is necessary to exclude associated injuries.

	Brainboost - which organs are retroperitoneal (Site not responding. Last check: )
		Retroperitoneal : organs without a mesentery and associated with posterior body wall, such as the aorta, inferior vena cava, kidneys and suprarenal glands..
		The retroperitoneal organs are somewhat protected by the organs that lie within the peritoneal cavity, and as such, injury to the retroperitoneal organs is often associated with injury to the organs of the peritoneal cavity..
		We can now see the intraperitoneal and retroperitoneal regions. The area within the peritoneum is referred to as intraperitoneal. Before we begin to place organs within the abdomen, we need to clarify the boundaries of the abdominal cavity (Figure 4): Superior (closest to the head) is defined by the breathing muscle - the diaphragm,..

		Idiopathic (non-malignant) retroperitoneal fibrosis has a generally good prognosis but a poor prognosis is associated with malignant retroperitoneal fibrosis, which occurs in response to metastatic tumour cells in the retroperitoneum.

	ACS :: Treatment Options by Stage
		Stage II seminomas are classified as either "nonbulky" or "bulky," which refers to the size of the retroperitoneal lymph nodes.
		Nonbulky tumors are treated with radical inguinal orchiectomy followed by radiation to the regional (retroperitoneal) lymph nodes.
		Cancer that comes back in the retroperitoneal lymph nodes after orchiectomy alone was performed for early stage tumors can be treated by surgery if the recurrence is small.

		The structures in the abdomen are classified as intraperitoneal, retroperitoneal or infraperitoneal depending on whether they are covered with visceral peritoneum and have a mesentery or not.
		Structures that are intraperitoneal are generally mobile, while those that are retroperitoneal are relatively fixed in their location.
		Some structures, such as the kidneys, are "primarily retroperitoneal", while others such as the majority of the duodenum, are "secondarily retroperitoneal", meaning that structure developed intraperitoneally but lost its mesentery and thus became retroperitoneal.
