Kidney disease is a primary or secondary to kidney and other organ diseases affect a kidney disease, the main clinical manifestations are some symptoms of urinary abnormalities and renal local, traditional Chinese medicine as the "kidney" meaning is more extensive, including endocrine diseases, symptoms of clinical manifestations of genital system. And the significance of commonkidney problems symptoms following a brief introduction.
A, urine abnormalities
1, oliguria and anuria, oliguria refers to 24 hour urine volume less than 400ml per hour or less than 17ml. without urine means 24 hours urine volume less than 50-100ml. of oliguria and anuria most associated with renal failure.
2, more than 24 hours urine: urine more than 3000ml per minute or more than 2ml. urine water intake, renal tubules and renal interstitial lesions, renal drainage increased in vivo and certain substances (such as glucose) excretion from urine too much.
3, nocturia: refers to the night (6 - night in the morning 6 points) more than half of the amount of urine urine. All day long and most of the renal dysfunction, renal insufficiency patients may have nocturia, some mental factors can also cause. But only the number and amount of urine urine increased who do not belong to the nocturia category.
1, frequent urination, urgency, dysuria: frequent urination refers to increased urination (normal average daytime voiding 4-6 times, 0-2 times at night). A urinary urgency means to urinate or just drained urine was in a hurry to row, often anxious and unable to control urination. The urethra during urination produces pain or burning sensation. These three symptoms is a characteristic manifestation of inflammation of the urinary system.
2, urinary retention: urination disorders cause urine bladder to stay in discharge. And relevant part of the urethra and complete obstruction, and some drugs can cause diseases of the nervous system.
3, urinary incontinence: refers to the involuntary urine from the urethra overflow. Visible on the lower urinary tract anatomy or dysfunction of neurogenic bladder.
Three, low back pain
1, renal colic pain: sudden onset, often to the lower abdomen, inner thighs and other parts of the vulva and radiation, intermittent severe angina pectoris. Often the ureter stones, blood or tissue necrosis caused by obstruction.
2, pain and pain of blunt kidney area: urinary system diseases caused by kidney pain include: 1) renal swelling traction supporting renal capsule caused, such as acute nephritis, acute pyelonephritis, hydronephrosis, polycystic kidney, kidney, kidney prolapse and.2) kidney disease caused by lumbago: such as renal abscess, renal infarction patients renal inflammation, renal cyst rupture and perirenal hematoma. However, many are caused by low back pain, spinal and paraspinal soft tissue diseases of pancreas, gallbladder, stomach pain often radiates to the waist.
The kidney is the main organ of the body to remove water, when the kidney disease, resulting in the water can not be discharged in vitro, retention in the body, called for renal edema. The degree of edema can be light weight, light had no visible swelling, only increased body weight (recessive edema) or in the early morning eyelid slightly swelling. Body weight can significantly even the chest, edema, ascites, body weight increased tens of kilograms (severe edema). The reasons causing edema are as follows:
1. when the kidney disease, kidney filtration area, lower permeability, and reduce blood flow, but the kidney reabsorption function intact, resulting in less urine.
The body's immune damage in the kidney 2. capillary wall body increased permeability, moisture permeability induced in plasma to tissue space.
3. kidney disease, reduced renal blood flow, renal parenchyma is blood, increased renin secretion, increased aldosterone secretion via the renin angiotensin system promotes the adrenal cortex, leading to renal tubular reabsorption of water, and the retention of sodium.
4. kidney disease, often have a lot of proteinuria, if a long time can cause lack of protein in the formation of hypoproteinemia, the plasma colloid osmotic pressure decreased extracellular fluid retention in tissues, causing edema. In addition, hypoalbuminemia may also cause the effective blood volume reduced, resulting in increased secretion of aldosterone and secondary antidiuretic hormone, renal reabsorption of water and sodium increased, causing edema.
