Communicating hydroceles frequently resolve spontaneously by the age of one. Therefore, surgical intervention is typically planned for children over one year old whose communicating channel (patent processus vaginalis) has not closed. In contrast, spontaneous resolution of a spermatic cord cyst is rare. Due to the risk of infection and potential pressure on structures within the inguinal canal, surgical correction for spermatic cord cysts is generally recommended. For these elective procedures, it is usually advised to wait until the child is older than one year, ensuring they are developmentally ready for surgery.
The surgical procedure for both spermatic cord cysts and hydroceles involves a small incision (approximately 1-2 cm) made in the lower abdomen, just above the groin crease. Through this incision, the patent processus vaginalis (the open channel associated with hydroceles and cord cysts) is identified and carefully separated from surrounding structures, including the spermatic cord (containing the vas deferens and blood vessels to the testis). The sac is then ligated (tied off) high within the inguinal canal using absorbable sutures, effectively preventing fluid communication between the abdominal cavity and the scrotum/cord. If an organ is found within the sac and is undamaged, it is gently returned to the abdominal cavity before ligation. The surgery typically lasts between 30 to 60 minutes. It is usually performed as a day-case procedure, allowing children to return home on the same day and resume their normal activities shortly thereafter. If deemed appropriate and planned in advance, circumcision may be performed concurrently.
Earlier surgical intervention may be considered for non-communicating hydroceles that are tense around the testis. Abdominoscrotal hydroceles, however, should be surgically managed promptly upon diagnosis. It is crucial to note that needle aspiration of congenital hydroceles is a hazardous approach; it carries a significant risk of infection, which can potentially lead to testicular loss.
