What are the best treatment methods for hydrocele of the tunica vaginalis?

Treatment methods for hydrocele of the tunica vaginalis can be divided into laparoscopic high ligation of the processus vaginalis, conventional transverse abdominal muscle incision with high ligation of the processus vaginalis, and oblique inguinal incision with high ligation of the processus vaginalis. The first two approaches have become the mainstream surgical techniques currently, while the oblique inguinal incision method is gradually being phased out. The oblique scar may sometimes be prominent and cosmetically unappealing; although the transverse incision in the abdominal muscles offers better cosmetic results, it is associated with a higher recurrence rate and is now rarely used in clinical practice. It is recommended that patients undergo laparoscopic high ligation of the processus vaginalis, with drainage of fluid after ligation, followed by one week of bed rest postoperatively. This minimally invasive procedure allows for rapid recovery, leaves no visible scars, reduces children's suffering, and is highly favored by families.
