The treatment of hydrocele in children mainly includes the following aspects: 1. Patients with mild hydrocele can take conservative therapy, so that the children can develop the good habit of urinating regularly and not holding urine, and regularly visit the pediatric clinic for follow-up observation. 2. If the degree of hydrocele is more serious, we should further understand the causes of hydrocele and treat the cause. If the condition is serious, patients who have little or no urine need to undergo cystostomy in time to keep the urine flowing smoothly.
