There is still a possibility of recurrence after hydrocele surgery in children, daily life management is needed to observe the patient’s condition, keep the surgical incision dry and clean, avoid strenuous exercise in the short term, and take medication as prescribed by the doctor. Surgery for hydrocele in children needs to be treated according to the cause of hydrocele, which mainly includes removing urinary stones, relieving ureteral obstruction and nephrectomy. After timely relief of obstruction, patients recover good renal function and have a better prognosis. However, it is still recurrent and may trigger hydronephrosis again if the primary cause, such as urinary tract stones, reappears. Therefore, surgical treatment does not mean that it will not recur in the future. After the operation of hydronephrosis in children, patients should be observed. After the operation, attention should be paid to keep the incision clean and dry to prevent secondary infection, appropriate activities, avoid strenuous exercise in a short period of time, develop good living habits, protect against cold and keep warm, pay attention to personal hygiene, and take medicines according to the doctor’s instructions.
