This is most common medical question that what is Anuria ? Anuria results in the complete absence of urine excretion. This may be due to obstruction of the renal ducts, functional impairment of the renal system, or as a result of dehydration of the body. The management of an anuria must be fast.
Definition of Anuria
What is Anuria ?
Anuria is a failure to eliminate urine from the body.
This involvement is, in most cases, a result of kidney failure. Indeed, the urinary system (consisting of the kidneys, ureters, gallbladder and urethra), allows the elimination of organic waste, the body. The kidneys have an important role of filter, allowing eliminating the organic waste of the blood, by the formation of the urine. The latter then passes through the ureters, into the gall bladder and into the urethra. A deficiency in this process of elimination of waste from the body can lead to the absence of urine formation, and therefore to Anuria.
Anuria is a medical emergency because it can have important consequences for the patient, or even be vital to him.
Causes of Anuria
The main cause of anuria is related to a deficiency in the renal system.
Acute renal failure, the reduction of the glomerular filtration capacity of the kidneys, is a common source. Kidney failure is itself caused by obstruction of the circulating channels in the kidneys, or by pathologies impacting the renal system.
Functional anuria (the cause of which is associated with an abnormality in the functioning of the renal system), and anuria by obstruction (caused by a blockage in the renal ducts, allowing the filtration of blood and urine production).
Renal failure can also be caused by dehydration of the body, no longer allowing the excretion of waste made by it.
Who is affected by Anuria?
Those most at risk of anuria are patients with renal impairment, or other conditions whose effects may be associated with a potential risk auric.
- Individuals exposed to dehydration are also at high risk of developing anuria.
- Evolution and possible complications of anuria
- The complications related to anuria can be more or less serious.
The first complication relates to an accumulation of non-excreted waste within the body. This waste passing through the blood, are therefore highly likely to be found in other organs, including vital.
The diagnosis and management of anuria must be effective at the earliest, in order to limit these risks of complications and in particular the vital risk for the patient.
The symptoms of Anuria
The first clinical signs of anuria correspond to a decrease in the abundance of need to urinate, even in the complete absence of these needs.
- Swelling of the bladder and pelvic pain may be characteristic symptoms.
- Bladder palpation and rectal examination confirm or invalidate this first clinical diagnosis.
Risk factors of Anuria
The main risk factors of an anuria are:
- The presence of an underlying renal pathology
- The presence of a pathology, the side effects of which may be associated with an impairment of The renal system
- Dehydration, more or less important.
How to prevent anuria?
Regular and adequate hydration is the first way to prevent anuria. It is recommended to drink between 1.5 L and 2 L of water per day per person. This volume is particularly to adapt according to the seasonality and the daily physical activity of the individual.
How to treat Anuria?
Anuria by obstruction is the most common form. In this context, the management of such an attack is based on the establishment of a urinary catheter, to cope with the obstacle in question and eliminate waste accumulated within the body.
When it comes to functional Anuria, and therefore to a deficiency in kidney waste disposal capabilities, emergency dialysis is necessary. This intervention allows, by an automatic system, to filter the blood and to extract the waste, role originally planned for the kidneys.
