The attack of acute pain, which appeared as a result of a sudden disturbance of outflow of urine, occurs in these states:
- urolithiasis disease;
- The omission of the kidney with the ureter bend;
- Injury of the kidney;
- Tuberculosis of the renal pelvis;
- Pyelonephritis, acute and chronic - in the acute stage;
- The tumor of the kidney.
Renal colic is most likely to occur with urolithiasis. Risk factors for its development are the following reasons:
- Suffering urolithiasis blood relatives;
- Loss of body fluids - a condition exsicosis;
- Prolonged fever, accompanied by fever;
- Kidney disease: pyelonephritis, urinary ducts, leading to scar deformity, narrowing the urinary tract;
- Errors in the diet, intake of poorly soluble products or drugs.
Renal colic in clinical practice occurs in 10% of men and 5% emergency cases in women. Urinary stone disease affects people of working age from 30 to 50 years. In half of the attacks of acute pain after a while repeated, that is, it has a tendency to relapse.
Renal colic, development mechanism
When blockage of the lumen calculus or ureteral compression outside the broken passage of urine. It continues to be produced, but as broken drain, collects in the renal pelvis, causing swelling of the tissues of the kidney. The receptors signal the tension pyelocaliceal system, alarm enters the spinal cord, forming the hearth surge receptors. After a while the pain impulses reach the cerebral cortex.
Renal colic symptoms
Regardless of the source of origin, the main feature of any colic - acute (stabbing) pain. With the defeat of the abdomen pain occurs in the abdomen and lower back. When developing renal colic, its symptoms are somewhat different from the pain associated with colic other sites.
The nature of the pain of the defeat of the urinary tract:
- The surprise is constant, cramping;
- Sufficiently long duration from a few minutes to 12 hours;
- The inability to make such a posture in which the pain subside.
Renal colic in children is accompanied by pain in the navel, accompanied by an increase in body temperature up to 37, 5
C, vomiting and intense fear.
When there is a blockage of the ureter in pregnancy, cramping in nature imitates the onset of labor, but the uterus is in a normal tone, but notes dizuricheskie symptoms: frequent urination with a small amount of urine.
Depending on the blockage of the ureter, it gives different reflections pain renal colic symptoms that indicate the anatomical localization of urinary tract obstruction. "Journey" stone stops constriction of the ureter, and in each case there is a different prevalence of pain:
- Aperture in the renal pelvis - in the middle region of the abdominal cavity;
- Crossing to the iliac arteries - the outer surface of the thigh and groin area;
- The mouth of the bladder - the lower abdomen;
- Inside the walls of the bladder - the urethra.
The resulting symptoms of renal colic is not only affecting the urinary system, but also the whole body. Ureteral obstruction often accompanied by the following symptoms:
- Paralytic ileus;
- Dizziness, fainting;
- High blood pressure;
- Rare pulse.
Contrary to popular belief, hematuria (blood in urine) occurs only when renal colic allowed. That is, the urinary tract stone leaves. As a rule, the size of calculus than 0, 5 cm promote independent offices with leaving urine. Stones found in the urine in the form of fine sand, which is also accompanied by the separation of acute pain.
In cases where renal colic develops against the background of cancer, hematuria occurs immediately, along with the pain.
Renal colic treatment
If further diagnosis using ultrasound examination on a portable sensor, patients are subject to emergency hospitalization in the following cases:
- Lack of effect of therapeutic interventions;
- A solitary kidney, or simultaneous destruction of two ureters.
If the first renal colic occurs, treatment is carried out in a hospital. This is necessary to determine the cause of kidney disease. When the introduction of antispasmodics and analgesics has a positive effect, the patient is not hospitalized, but the data is forwarded to the clinic for outpatient monitoring.
Since promedol and its analogues induce a strong relaxation, due to which the ureter stone moves uncontrollably, so that the volume of transactions increased by several times, today renal colic is not stopped narcotic drugs!
In order to relieve acute pain medication administered to block the main pain mediators - prostaglandins. For this purpose, non-narcotic analgesics action.
Renal colic, acute care
For self-help, but not self-developed some guidelines to help bear the pain before the arrival of "first aid". When the pain of weak intensity and accurately known diagnosis of urolithiasis makes a hot bath. In the absence of conditions for bathing, when starting renal colic, acute care is limited to taking antispasmodic (No-Spa) and by applying a hot water bottle to the lower back.
It is advisable to visit the doctor to collect urine for analysis. Timely laboratory testing is so important that often save the patient's life.
