What is the cause of retroperitoneal fibrosis?
The exact cause of retroperitoneal fibrosis is not known in about two-thirds of the affected individuals (idiopathic). A drug used in the treatment and prevention of migraine headaches (methysergide) may be the cause of this rare disorder in 12 percent of cases.
How does retroperitoneal fibrosis cause hydronephrosis?
The retroperitoneal fibrosis mass centers around the distal aorta between L4 and L5 and encases the ureters. This can lead to hydronephrosis via extrinsic compression on the ureters leading to interference with ureteral peristalsis. Presenting symptoms usually include lower back and/or flank pain.
What is ureteral fibrosis?
Fibrosis is the growth of excess connective tissue, which causes a mass to form. This often causes compression and blockage of the ureters, which are the tubes that carry urine from your kidneys to your bladder. Tissue masses can block one or both of your ureters.
What is Ormond’s disease?
Idiopathic retroperitoneal fibrosis also known as Ormonds disease is a rare disorder characterized by the development of fibrotic tissue in the retroperitoneum involving the abdominal aorta and iliac arteries, ureters and the inferior vena cava.
What causes fibrosis of the kidney?
Diabetes and hypertension are currently the two principal causes of CKD (2), among other causes such as infectious glomerulonephritis, renal vasculitis, ureteral obstruction, genetic alterations, autoimmune diseases (1) and drugs (3,4).
Are ureters retroperitoneal?
The primary retroperitoneal organs are the adrenal glands, kidneys, ureter, the abdominal aorta, inferior vena cava and their branches.
What causes retroperitoneal edema?
Kidney infections, abscesses , stones, and other causes of inflammation or infection of the kidneys can cause retroperitoneal inflammation. A ruptured appendix, stomach ulcers, or a perforated colon can allow bacteria into your retroperitoneal space.
What is Circumcaval ureter?
A circumcaval ureter is a rare congenital anomaly usually associated with upper urinary tract stasis and an “S” or “fishhook” deformity of the ureter, in which the ureter itself passes behind the inferior vena cava.
What drugs cause retroperitoneal fibrosis?
The particular incidence, in the last four decades past century, of the RPF due to long-term use of ergot alkaloid derivatives (ergotamine, methysergide, pergolide, bromocriptine, cabergoline) and specific L-dopa derived agents, such as methyldopa, as well as to different analgesics, came progressively down given that …
Does fibrosis cause kidney problems?
A final, common pathway in chronic kidney disease is fibrosis, the formation of internal scar tissue, which can cause devastating effects. In the kidneys, it can ultimately lead to end-stage kidney failure.
Can UTI cause kidney scarring?
Renal scarring can be a permanent consequence of urinary tract infection (UTI), and is associated with long-term conditions such as decreased renal function and hypertension.
What causes the ureter too narrow?
A ureteral stricture frequently results from a buildup of scar tissue or inflammation around the ureter, often due to an external traumatic injury or as a complication of a previous surgery, such as a procedure to manage kidney stones or surgeries that affect the area surrounding the ureters, including gynecologic or …
Is retroperitoneal fibrosis malignant?
Introduction. Retroperitoneal fibrosis (RPF) is characterized by a highly fibrotic retroperitoneal mass and encompasses the idiopathic form and secondary to malignancies.
Is urinary bladder retroperitoneal?
The bladder is not considered a retroperitoneal organ. A retroperitoneal organ is an organ described as located behind the peritoneum (the serous…
What is Retrocaval ureter?
Retrocaval ureter also referred to as pre-ureteral vena cava is a rare congenital anomaly with the ureter passing posterior to the inferior vena cava. Though it is a congenital anomaly, patients do not normally present with symptoms until the 3rd and 4th decades of life from a resulting hydronephrosis.
What causes ectopic ureter?
Ectopic ureter has no known cause. Scientists don’t yet understand why ureters sometimes form differently while a fetus is developing. However, this congenital abnormality often runs in families. If you have an ectopic ureter, each of your children has a 50% chance of developing it.
What organ is located in the retroperitoneal space?
The area in the back of the abdomen behind the peritoneum (the tissue that lines the abdominal wall and covers most of the organs in the abdomen). The organs in the retroperitoneum include the adrenal glands, aorta, kidneys, esophagus, ureters, pancreas, rectum, and parts of the stomach and colon.
What is the cause of fibrosis?
What causes pulmonary fibrosis? There are a number of known causes of pulmonary fibrosis. Exposure to toxins like asbestos, coal dust or silica (including workers in the coal mining and sandblasting industry) can lead to pulmonary fibrosis.
Is RPF an autoimmune disease?
One intriguing aspect of idiopathic RPF is its association with autoimmune disorders, which highlights the pathogenic relevance of autoimmune mechanisms.
