kidney calcium milk
Introduction
Introduction to kidney calcium milk Calciummilkofthekidney refers to a suspension of calcium-containing particles in the renal pelvis, which is actually a special type of urolithiasis. Due to the relationship of gravity, the position of calcium milk particles changes with the change of body position, and its formation is related to urinary tract obstruction, urine concentration and chronic inflammation. Kidney calcium milk is composed of many fine calcium containing 0.2-0.5 mm in diameter. The granules are suspended in the renal pelvis, the suspension formed by the renal cyst or the hydronephrosis, the obstruction and inflammation, the renal unit secretion and reabsorption dysfunction, the urine in the renal pelvis is gradually concentrated, so that Crystal components such as calcium and phosphate are precipitated in a saturated state to form calcified particles. basic knowledge The proportion of illness: 0.002% Susceptible people: no special people Mode of infection: non-infectious Complications: urethra stones
Cause
Kidney calcium milk cause
Cause of the disease (45%):
Kidney calcium milk is a suspension formed by many fine calcium-containing granules with a diameter of 0.2-0.5 mm in the renal pelvis, renal cyst or hydronephrosis, obstruction and inflammation, kidney The unit secretes and reabsorbs dysfunction, and the urine in the renal pelvis gradually concentrates, so that crystal components such as calcium and phosphate are precipitated and precipitated to form calcified particles.
Pathogenesis (30%):
The pathogenesis of renal calcium milk is still inconsistent. Because calcium milk is heavier, it can be deposited at a lower position with body position changes. In a few cases, calcium particles are doped with some coarse particles, which can be stacked into a group, and calcium milk enters. The ureter can be discharged by itself, occasionally blocking the ureter, causing symptoms similar to ureteral stones.
Prevention
Kidney calcium milk prevention
There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.
1. Adjust daily life and workload, and regularly carry out activities and exercise to avoid fatigue.
2. Maintain emotional stability and avoid emotional excitement and tension.
Complication
Renal calcium milk complications Complications, urethra stones
Often combined with upper urinary tract stones.
Symptom
Renal calcium milk symptoms Common symptoms When bending over, low back pain, kidney area, tenderness, kidney area, snoring, fever, hematuria
Patients may have a history of urinary tract infections; some patients have a history of primary hyperparathyroidism, similar to the clinical manifestations of kidney stones, most patients have no obvious clinical symptoms, and some patients may have low back pain, renal colic, Hematuria and other symptoms, combined with diverticulum infection, can increase back pain, and have systemic symptoms such as fever.
Examine
Kidney calcium milk examination
Urine routine examination can have microscopic hematuria. When infected, there may be white blood cells or pus cells in the urine.
Film degree exam:
1B Ultra: A liquid dark area showing the renal diverticulum or hydronephrosis with a round echo group.
2KUB flat film: visible in the kidney area, the circular, uneven density of "sesame"-like shadows, such as the standing position film, the shadow becomes a half moon shape, and visible the liquid level formed by the characteristic calcium milk sinking, this It is a typical renal calcium milk performance.
3IVU: It can show the relationship between renal calcium milk and the collecting system. The contrast agent can't enter the sputum room when the neck is obstructed.
4 retrograde angiography: Retrograde angiography is feasible when IVU development is not satisfactory, and the channels of the diverticulum and the collecting system are even visible.
5CT examination: The half moon shape of the calcium milk particles formed on the scans in the supine and prone positions changes with the change of body position.
Diagnosis
Diagnosis and differential diagnosis of renal calcium
According to the medical history, clinical symptoms and signs, combined with characteristic imaging examination can be diagnosed.
1. Kidney stones: patients may have pain in the kidney area and cramps, and there may be microscopic hematuria or gross hematuria. KUB plain film and IVU can be seen in the shadow of stones, but whether it is single or multiple stones, the shape of the shadow does not follow the body position. Change and change, the distribution is obviously different from kidney calcium milk, the latter is mostly "sesame"-like distribution.
2. Multiple small stones in the renal pelvis: due to the narrowing of the neck of the renal pelvis, the hydronephrosis can be combined with multiple small stones. The clinical manifestations are similar to those of renal calcium milk. It is difficult to identify. On the X-ray film, when changing the body position, Although the morphology may vary with body position, the particles of the stone are larger than the renal calcium milk.
3. Gallbladder calcium milk: There may also be calcium milk formation in the gallbladder. Its clinical manifestation is not easy to distinguish from the right kidney calcium milk. It is generally difficult to identify by X-ray examination and B-ultrasound examination.
