Renal cysts are the most common structural abnormalities in adult kidneys. They are cystic benign masses that grow in the kidney. They are generally spherical and can be one or more. They can grow only on one side of the kidney, Can also have both kidneys. The incidence of renal cysts is about 2% in 30-40 years of age, about 10% in 50-70 years old, and 20% -30% of the elderly over 70 years old will have renal cysts.
Simple renal cysts are generally smaller, 0.5-2 cm in diameter, thin and transparent wall, the capsule usually wrapped in a light yellow liquid, is filtered out of the plasma composition. Simple renal cysts generally no symptoms, only when the cyst compression caused by vascular occlusion or urinary tract obstruction may appear when the corresponding performance.
The cause of renal cysts is not yet very clear, may be acquired the formation. With age, cysts will gradually increase and increase, larger cysts may cause abdominal pain, back pain and other symptoms, in a few cases may even occur cyst hemorrhage, infection and so on.
Kidney cysts less than 5 cm in diameter are asymptomatic and generally untreated. Review every six months to a year B-ultrasound, follow-up observation on it. Advise patients to maintain good living habits, drink plenty of water, stay up late, do not take drugs.
Kidney cysts with a diameter of more than 5 cm, or symptoms of compression around the surrounding tissue, causing urinary tract obstruction, or repeated intracapsular bleeding, infection, to be further assessed nephropathy, if necessary, feasible surgical treatment, commonly used treatments include laparoscopic cyst To the top decompression, B-guided cyst puncture fluid extraction and so on. For large renal cysts larger than 10 cm in diameter, surgery is often required.
Renal cysts and polycystic kidney disease are two distinct diseases. Polycystic kidney disease is a genetic disease, there are two types, infantile polycystic kidney disease and adult polycystic kidney disease.
Adult polycystic kidney disease often found in middle-aged youth, polycystic kidney disease common type. More renal cysts, and progressive increase, causing renal structure and dysfunction, and often accompanied by the performance of other systems other than the kidneys. Mainly for bilateral renal enlargement, kidney pain, hematuria, hypertension, anemia, renal failure and so on.
Once polycystic kidney disease is found, it is recommended to actively visit the Department of Nephropathy, also recommended parents, siblings, children and other relatives are also related to screening, so that problems early detection, early treatment, protection of renal function.
