The retroperitoneal space (retroperitoneum) is the anatomical space (sometimes a potential space) behind (retro) the peritoneum. It has no specific delineating anatomical structures. It has no specific delineating anatomical structures.
The management will depend on the location of the bleeding, the stability of the patient and the cause. Thus, the patient needs to be closely monitored and the etiology investigated. The initial management must include adequate fluid resuscitation.
Perinephritis is an infection of the surroundings of the kidney either right or left. It can be the result of extravasated infiltration of the bacteria out of the renal pelvis (pyelonephritis) or a result of another kidney infection.
The retroperitoneum or retroperitnium is an anatomical region that includes the peritoneum-covered organs and tissues that make up the posterior wall of the abdominal cavity and the pelvic space - which extends behind to the abdominal cavity. Definitions vary and can also can include the region of the wall of the pelvic basin.
adipose capsule of kidney (or perirenal fat, or perinephric fat) renal fascia; pararenal fat; peritoneum (anteriorly), and transverse fascia (posteriorly). Sometimes the adipose capsule of the kidney also known as the perirenal fat, is regarded as a part of the renal capsule. [4]
These layers thus form two potential spaces where fluid can form, the small subcapsular space and the large perinephric space. The renal capsule is fibrous and does not easily expand. [1] Thus, even a small collection of blood in the subcapsular space can cause mass effect on the renal parenchyma. [citation needed]
Fluid shifts occur when the body's fluids move between the fluid compartments. Physiologically, this occurs by a combination of hydrostatic pressure gradients and osmotic pressure gradients. Water will move from one space into the next passively across a semi permeable membrane until the hydrostatic and osmotic pressure gradients balance each ...
Peritoneal fluid is a serous fluid made by the peritoneum in the abdominal cavity which lubricates the surface of tissue that lines the abdominal wall and pelvic cavity. It covers most of the organs in the abdomen. An increased volume of peritoneal fluid is called ascites. Sampling of peritoneal fluid is generally performed by paracentesis.
