Cloudy urine with oil bloom is usually seen in fatty urine and celiac disease. The former is most often seen in nephrotic syndrome and is mainly caused by damage to the barrier of the glomerular basement membrane. A large amount of lipid in the blood is filtered through the glomerulus into the renal tubules, which have limited reabsorption capacity, so the urine can have a large number of fat droplets to form steaturia. At this time, if fat droplets are extracted by mixing organic solvents such as ether and ethanol, the urine can become clear. Celiac disease, on the other hand, is mainly caused by poor reflux of lymphatic fluid, which refluxes into the urine. The main causes of its appearance are lymphatic obstructive diseases, such as filariasis and retroperitoneal tumors. Filarial worms can infest the perirenal lymphatic tracts and the eggs can block the lymphatic vessels therefore there can be a large amount of lymphatic fluid in the urine. Retroperitoneal tumors are mainly seen in kidney cancer and cancer emboli blocking lymphatic vessels, causing lymphatic reflux obstruction, so there can be a large amount of lymphatic fluid in the urine. Cloudy urine with oil flowers promptly seek medical attention and further treatment under the guidance of a doctor.
