How to check chyluria

Under normal circumstances, the urine should be clear. It is normal to be occasionally accompanied by yellow or white urine with some foam. However, some people may have chyluria, which requires examination first. You can check the texture of the urine and whether the fat or blood lipids are high. At the same time, multiple tests should be done to see if there are any problems with the patient's intestines, bladder, and urethra.

Urine chyle qualitative test

examine

1. Laboratory examination

1. Urine test

After placing the urine sample in a glass container and letting it stand for observation, it can be divided into three layers: the upper layer is a white lipid membrane; the middle layer is chyle, and the lower layer has a large number of red and white blood cells and fat globules visible under a microscope; the urine protein is positive; and the ether test is positive.

2. Urinalysis

Urine lipids are high, but blood lipids are not high.

3. 24-hour urine protein measurement

Significantly increased.

4. Biochemical examination

Plasma protein decreases and liver function may be abnormal.

5. Microfilariae examination

Microfilariae examination in blood and urine may be positive.

(II) Inspection of auxiliary equipment

1. Cystoscopy

Examination after a high-fat meal or drinking milk may reveal milky white urine spraying from the bilateral or ipsilateral ureteral orifices.

2. Retrograde pyelography

A few cases may show pelvic and calyceal lymph reflux and dilatation of perirenal lymphatic vessels. However, when the contrast agent is injected too quickly and with too high pressure during retrograde pyelography, this type of imaging may also occur in patients with non-chyluria, so positioning diagnosis is of little significance.

3. Lymphangiography

It is the most important inspection method. It can show the location, number and degree of pathological communication between the lymphatic system and the urinary tract. The angiography showed tortuous and dilated renal pedicle lymphatic vessels and the outlines of the renal pelvis and calyces; the retroperitoneal lymphatic vessels continued to develop, showing uneven thickness, even bamboo-like, and the lumbar trunk may extend beyond the transverse processes of the spine; the lymph nodes had filling defects.
