Renal colic

Introduction to renal colic Renal colic, also known as kidney and ureteral colic, is caused by an acute obstruction of the renal pelvis, ureteral smooth muscle spasm or luminal due to a cause, and its occurrence is not related to whether the body is strong or not. It is characterized by sudden onset of severe pain, which occurs from the affected side of the waist along the ureter to the lower abdomen, the groin, the inner thigh, the testicles or the labia, which can last for a few minutes or tens of minutes, or even hours. Attacks are often accompanied by nausea and vomiting, sweating, pale, uneasiness and other symptoms, severe cases can lead to shock. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: urinary tract obstruction, hydronephrosis, anemia

Cause of renal colic

Infection factor (25%):

The most common pathogen caused by infection is renal Staphylococcus aureus. The bacteria can enter the kidney from other parts of the suppurative lesion through the blood, such as sputum, pain, abscess, infected wound, upper respiratory tract infection, and renal proximity. Tissue infection, etc. The initial lesion is limited to multiple microscopic abscesses in the renal cortex, which can be combined into multiple atrial abscesses. Some patients can be merged into small abscesses into small abscesses and become renal colic. A small number of patients to advanced stage, near cortical renal colic can be worn The membrane develops into a perirenal abscess, and the abscess of the proximal renal pelvis can be perforated and drained to the renal pelvis, and bacteria can be found in the urine.

Other reasons (20%):

Such as cysts, stones, etc. can also cause renal colic, usually ureteral stones can cause severe pain; renal cysts and various types of nephritis can also cause renal colic due to renal interstitial damage; long sitting or walking After a long time, I feel the acidity and swelling of the kidneys.

Kidney stones (40%):

The most common cause of renal colic is kidney stone. Followed by kidney cysts and various types of nephritis. If the patient has such a situation, he can go to the hospital to check the kidney B-ultrasound, see if there are kidney stones, cysts and other diseases, and then check the urine routine to see if there is kidney disease. If the examination is normal, then you can see Chinese medicine treatment, may be kidney deficiency or low back pain.

Renal colic prevention

Usually pay more attention to rest, try to avoid heavy physical activity and strenuous exercise. Prevents sputum, pain, abscesses, wound infections, upper respiratory tract infections, and infections of adjacent kidney tissue infections.

Renal colic complications Complications, urinary tract obstruction, hydronephrosis

Urinary tract obstruction could not be found in time. Causes varying degrees of hydronephrosis. Over time, hydronephrosis can become more and more serious, eventually leading to loss of kidney function.

May cause gastrointestinal symptoms, anemia, etc.

Symptoms of renal colic, common symptoms, low back pain, severe pain, one side, severe abdominal pain, groin pain, nausea and vomiting

Renal colic often manifests as sudden and severe pain, mostly located on one side of the rib angle, showing sharp pain, squeezing, and radiating along the ureter to the lower abdomen, the inner thigh, and the vulva. Accompanied by sweating, nausea and vomiting.

Pain-inducing factors are often physical labor, strenuous activities, and travel bumps. The pain is caused by the movement of stones to bruise the renal pelvis and ureteral mucosa, causing local smooth muscle spasm, contraction, and more with microscopic hematuria or gross hematuria, but the amount of bleeding is not related to the size of the stone and the degree of obstruction.

20% to 25% of the pain does not have hematuria. Children performed the same, but 30% of patients had only painless hematuria. Signs may have sputum pain in the affected side of the kidney, ureter and bladder tenderness.

Examination of renal colic

1. Regular inspection.

2, B-ultrasound: B-ultrasound can obtain the cut surface image of the organ to be examined, can directly carry out intuitive morphological observation, can clearly display the structure of the kidney, according to the automatic measurement data character display, understand the size of the lesion and other objective data .

3, urine routine: a clinical examination can not be ignored a preliminary examination, many kidney lesions can appear in the early stages of proteinuria or urine sediment. Once a urine abnormality is found, it is often the first indication of a kidney or urinary tract disease and is often an important clue to the nature of the pathological process.

Diagnostic identification of renal colic

Because renal colic is often accompanied by gastrointestinal symptoms such as nausea, vomiting, and abdominal distension, it is easy to be confused with acute abdomen. Therefore, the following common acute abdomen should be excluded in the diagnosis: acute appendicitis, acute cholecystitis and acute pancreatitis; Female patients should also be excluded from ovarian cyst torsion, ectopic pregnancy, acute salpingitis.

Urine routine and B-ultrasound examination can generally determine whether there is renal colic, in which "red blood cell ++" in urine routine means that it is meaningful. If only one + or female patient is in menstruation, this result cannot be used as a basis for diagnosis. Do not use painkillers repeatedly until they are diagnosed, otherwise it will affect the observation of the condition and even delay the diagnosis.
