Right kidney cystic lesion

Right renal cystic lesions are a disease that mainly occurs in adult males. It is generally a unilateral disease, and the older the patient is, the higher the incidence rate. It can cause symptoms such as vascular nasal congestion and urinary tract obstruction. It is recommended that patients should receive timely treatment. As long as the symptoms of right kidney cystic lesions are present, they can generally be relieved by injecting sclerosing agents. You can learn about the specific treatment and diagnosis methods.

Renal cyst is the most common structural abnormality of the kidney in adults. It can be unilateral or bilateral, one or more, and is generally about 2 cm in diameter. There are also cysts with a diameter of up to 10 cm. It is more common in males. The incidence rate increases with age. Simple renal cysts generally have no symptoms. Only when the cyst compression causes vascular occlusion or urinary tract obstruction may corresponding symptoms appear, which may affect renal function. When the cyst is larger than 5 cm, appropriate treatment should be performed, including cyst fluid aspiration and intracystic injection of sclerosing agents or surgical treatment.

Among the renal cysts we commonly see, most are simple renal cysts, while hereditary renal cystic diseases account for a relatively small proportion. Simple renal cysts are almost non-existent in people under 20 years of age. If cysts develop in individuals under 20 years of age, congenital kidney development problems or hereditary renal cystic diseases should be highly suspected. The incidence of renal cysts increases with age. The incidence of simple renal cysts is about 10% between the ages of 30 and 40. By the age of 80, the incidence of simple renal cysts reaches more than 50%. Simple renal cysts are more common in men.

Differential Diagnosis

The presence of cysts in the renal parenchyma needs to be differentiated from the following diseases: ① necrosis and liquefaction of solid renal tumors; ② canceration on the basis of renal cysts, which is extremely rare; ③ autosomal dominant polycystic kidney disease.

treat

Since simple renal cysts are mostly asymptomatic and have little effect on renal function and surrounding tissues, they do not require treatment and only require follow-up for 6 months to 1 year. If the cyst is large in diameter, exceeding 5 cm, or produces symptoms of compression of surrounding tissues, causing urinary tract obstruction, cyst fluid aspiration and intracystic injection of sclerosing agent are required. If the cyst is large, with a diameter greater than 10 cm, surgery may be required.
