I. Introduction: Celiac disease is divided into filarial celiac disease and non-filarial celiac disease. The common filarial celiac disease, which accounts for more than 95% of cases, is caused by the infection of the lymphatic system by filarial parasites of Bangs, and is a distant complication of hematosiderosis. Non-filarial celiac disease is caused by tuberculosis, malignant tumors, surgery, etc., which invade the lymphatic system and cause celiac disease (lymphatic fluid) to drain through the kidneys. After the lymphatic system is infected by filarial parasites, the lymphatic vessels become tortuous and dilated, the lymphatic fluid flows poorly and accumulates in the lumen, the pressure in the lumen increases, the valve function is destroyed, and the celiac lymphatic fluid flows back into the kidney and soaks into the renal calyces and renal pelvis, forming a celiac fistula, and a large amount of fat and protein is eliminated with the urine, causing malnutrition and hypoproteinemia in patients. Celiac disease can also appear in other body cavities, scrotum and lower limbs under the skin, and can be seen clinically in celiac chest, celiac abdomen, rubber swelling, rubber leg, etc. Clinical symptoms: The main clinical symptoms are: cloudy and white urine like rice swill, or like cow’s milk, or like horse urine, or like soybean milk. Some patients with bleeding occur celiac hematuria, urine red and muddy, or like blood, or like washing meat water; or red clots, or like lean meat, or like pig liver, or red and white clots like powder ball, or red with white, or white with red, or like hawthorn cake, or like ice ball, or like red bean popsicles, all kinds of. Accompanying symptoms include: back pain, abdominal pain, chills, and fever. Symptoms are aggravated by exertion or by eating high-fat, high-protein foods, and colic may occur if a celiac clot obstructs the ureter. If a mass occurs in the bladder, painful urination may occur when it is discharged, and if it obstructs the urethra, clinical emergencies such as “acute urinary retention” may be formed. Diagnosis: There is often a history of living in filarial infected areas, the clinical manifestations of urine are white or red and muddy, and the urine celiac test is positive (fat globules are detected in urine). Auxiliary tests: routine urine and urine celiac test are still commonly used in clinical practice because of their simplicity and ease of use. Ultrasound and biochemical tests can be used to differentiate from other renal diseases, and cystoscopy, where celiac urine is ejected from the ureteral orifice, or celiac clots are visible. Retrograde pyelogram, which can show pelvic lymphatic reflux, such tests and lymphangiogram have certain effects on the body can be selectively examined.
