Uremia is a full bladder don't come out

Someone full bladder after a period of time, even if the discharge will consciously alvine bilge painful, this is the bladder after expansion because of incomplete contract. In addition, a full bladder too long, the pressure inside the bladder, metabolism, is bound to damage the kidneys excrete waste water and waste products accumulate in the body, causing uremia, cause kidney failure, life-threatening.
Progressive renal unit function is lost, in renal insufficiency in renal failure. A normal person, however, there are 2 million renal units, at the same time, not all renal unit work, some nephron accept less blood, at rest nephron (standby). Loss of progressive renal disease, these reserves, has a number of renal unit function decreases, and further increase the residual nephron burden, the renal unit discharge and the amount of waste water is limited, moisture and nitrogen waste will accumulate in the body, clinical occurrence uremia.
Poor drainage of urinary tract obstruction of urinary tract, such as benign prostatic hypertrophy, or some anatomical defects caused by urine reflux, cause renal pelvis and calyces expansion, said kidney seeper, oppression normal renal tissue, causing kidney failure. Kidney disease diabetes, about half of renal failure in five years, and the other complications of diabetes, such as the reticuloendothelial system, cardiovascular system and nervous system complications can also appear at the same time.
Polycystic kidney is a congenital disorder, can come on a few patients in the same family. Pathological examination showed developmental defect of water filling capsule. Oppression of normal renal tissues. The illness can be hidden for a long time, until the enlarged kidneys after 40 ~ 50 years old, apparent kidney function not all-rounder diagnosis of polycystic kidney.
Urine is the product of metabolism of kidney, kidney to produce urine way to adjust the body of excess water, excrete metabolic wastes and toxins produced by the body metabolism. Diet and metabolism in the body of water every day, in the body with the blood flow into the kidney. Kidney with so many "filter" by the name of glomerulus.
Interstitial nephritis of incidence of chronic renal failure in second place. Renal tubular atrophy, fibrosis, and scarring in glomerular declining blood supply and renal function. Analgesic caused by kidney disease, gouty nephropathy renal toxicity of drugs and antibiotics and other kidney disease belong to interstitial nephritis.
The human body has a strong compensatory ability, can properly adjust the biochemical processes in the body of the disorder. Sometimes we can see only the remaining 10% of the patients with normal renal function, can still maintain a life. Kidney disease, renal failure caused by itself, as a result of heart failure, shock, or other reasons cause blood pressure to drop, renal hypoperfusion, also can cause kidney failure, called renal failure kidney before sex. And after kidney kidney failure is the main reason of the urinary tract obstruction and urine reflux.
Acute renal failure can be due to excessive blood loss, dehydration, and heart failure caused by low blood pressure, renal hypoperfusion, acute glomerulonephritis, explosive pyelonephritis, the transplant renal acute rejection reaction and toxicity to kidney with special material, such as mercury, bismuth, phosphorus, carbon tetrachloride, and some pathogens and antibiotics and other drugs. Proper treatment of acute renal failure, kidney function can be restored, acute renal failure from the onset to the basic renal function recovery, it will take about 2 ~ 4 weeks, in this stage, most patients need blood dialysis to sustain life.
Renal failure can appear within a few months, also can in delay for years, until serum urea and creatinine increased, half fell to normal renal function, symptoms arise. Sometimes a few years after onset, until after the terrible uremia symptoms, was diagnosed with glomerulonephritis. Duration long diabetic patients, diabetic nephropathy part people can appear kidney complications, especially the youth type or type I diabetes patients can appear proteinuria, this is often a kidney involvement of the first indications.
