Renal cysts are a common structural abnormality of the kidneys in adults, which can be divided into unilateral and bilateral types. They are more common in males, with a diameter of about 2cm. As age increases, the probability of occurrence increases, and fetuses may also suffer from such symptoms. So, will the fetal left kidney cyst disappear on its own?
Renal cysts generally do not have obvious discomfort symptoms, but when the cyst compresses blood vessels, causing occlusion or urinary tract obstruction, it can affect renal function. If the cyst exceeds 5cm, corresponding treatment is needed. The common cause is renal tubular diverticulum, which often presents with intermittent pain in the waist, abdomen, and back. It does not belong to congenital hereditary kidney disease, but is formed after birth.
The occurrence of unilateral cysts in the fetus is due to incomplete kidney development. Unlike adults, most fetuses can disappear on their own in the later stages of development. If the fetus only has cysts and does not cause damage to other organs, it can choose to continue pregnancy, undergo prenatal check ups, and regularly go to the hospital for follow-up examinations. If accompanied by severe hydronephrosis, timely treatment is necessary to prevent harm to the fetal urinary system.
After one month of birth, the fetus can go to the hospital for B-ultrasound examination to identify the specific cause of left kidney cyst. Different types of lesions require different treatment methods. If it is hydronephrosis, it can be divided into mechanical and functional types. The former requires surgical treatment, while the latter can be observed. The cyst may gradually disappear.
