Fatty nephrosis is a disease with many names, the most common is the term "nephrotic syndrome" for all conditions of weak kidney, causing inflammation, edema, protein in urine, hypoproteinemia and hyperlipidemia.

Nephrotic syndrome occurs when the kidneys are damaged. If not diagnosed early and treated actively, prolonged proteinuria will cause a series of dangerous diseases and complications.

Nowadays, the number of people suffering from kidney and urinary tract diseases is increasing. To detect kidney-related diseases early, ultrasound is an extremely effective method. Renal ultrasound technique is used to determine the location, shape, structure, size and relationship between the kidneys and other organs.

Medullary sponge kidney, also known as sponge kidney, is considered a benign disorder with a relatively low incidence. However, about 10% of patients with sponge kidney are at risk of developing diseases related to urinary tract infections and kidney stones, causing patients to struggle to filter kidney stones every year. Therefore, we should not be subjective and negligent in early detection and treatment of this disease.
