Eligibility
Inclusion criteria
Inclusion criteria: 1. Diagnostic Criteria: Confirmed diagnosis of congenital hydronephrosis via abdominal ultrasound, meeting the criteria for urinary tract dilation grading (Grades I–III), defined as a fetal renal pelvis anteroposterior diameter of >= 4 mm or a postnatal renal pelvis anteroposterior diameter of >= 7 mm, or accompanied by symptoms such as calyceal dilation or changes in renal parenchyma. 2. Feasibility of Follow-up: The guardian commits to cooperating with a 3-year follow-up, is able to attend regular examinations at the research center, and has stable contact information. 3. Informed Consent: The legal guardian voluntarily participates in this study and signs a written informed consent form.
