Classification of renal cysts

Simple renal cyst

It may be a congenital abnormality, with one or both kidneys having one or more round cystic cavities of varying sizes that are not connected to the outside world. Most of them are unilateral, so it is called simple renal cyst. The incidence rate may increase with age. 50% of people over 50 years old can be found in this cyst by B-ultrasound. It can be diagnosed with the help of B-ultrasound and CT.

Adult renal cyst

It is a congenital hereditary disease. The renal parenchyma is filled with countless round cysts of varying sizes that are not connected to the outside world. The cysts contain fluid. The small ones are invisible to the naked eye, and the large ones can be several centimeters. Therefore, it is called polycystic kidney. Symptoms include increased nocturia, low back pain, high blood pressure, etc. Urinalysis may reveal hematuria and a small amount of proteinuria, which often slowly develops into chronic renal failure. 10% of people have kidney stones and 30% have polycystic liver disease. An experienced doctor can confirm the diagnosis with the help of B-ultrasound and intravenous pyelography.

Acquired renal cyst

It mainly occurs after uremia or dialysis treatment. It has nothing to do with age, but is related to the duration of hemodialysis. The kidneys originally do not have renal cysts. According to literature reports, most patients who have been on dialysis for more than 3 years will develop cysts. There are at least 4 cysts in one of its kidneys, most of which are 2 to 3 centimeters in diameter. Some cysts can become infected or even cancerous, and the diagnosis can be confirmed by B-ultrasound or CT examination.

Dietary precautions

Be careful not to eat too salty foods (including pickled foods), spicy foods (including peppers, alcohol, shrimps, crabs, etc.), contaminated foods (including rotten and spoiled foods, leftovers, etc.), and barbecued foods. People with renal insufficiency or uremia should also be careful not to eat beans and their products, and limit high-protein animal foods and greasy foods.
