Individualized minimally invasive treatment for adult testicular hydrocele: A pilot study

BACKGROUND: Hydrocelectomy is the gold standard for the treatment of hydrocele, but it often causes complications after surgery, including hematoma, infection, persistent swelling, hydrocele recurrence, and chronic pain. In recent years, several methods for minimally invasive treatment of hydrocele have been introduced, but they all have limitations. Herein, we introduce a new method of individualized minimally invasive treatment for hydrocele. AIM: To present a new method for the treatment of adult testicular hydrocele. METHODS: Fifty-two adult patients with idiopathic testicular hydrocele were included. The key point of this procedure was that the scope of the resection of the sheath of the tunica vaginalis was determined according to the maximum diameter (d) of the effusion measured by ultrasound and the maximum diameter of the portion of the sheath pulled out of the scrotum was approximately πd/2. The surgical procedure consisted of a 2-cm incision in the anterior wall of the scrotum, drainage of the effusion, and dissection of part of the sheath of the tunica vaginalis. After the sheath was peeled away to the predetermined target extent, the pulled-out sheath was removed. The intraoperative findings and postoperative complications were analyzed. RESULTS: All patients were successfully treated with a median operation time of 18 min. The median maximum diameter of the effusion on ultrasound was 3.5 cm, and the median maximum diameter of the resected sheath was 5.5 cm. Complications occurred in four (7.7%) patients: two (3.8%) cases of mild scrotal edema, one (1.9%) case of scrotal hematoma, and one (1.9%) case of wound infection. All of the complications were grade I-II. Recurrent hydrocele, chronic scrotal pain, and testicular atrophy were not observed during a median follow-up of 12 mo. CONCLUSION: We report a new technique for individualized treatment of testicular hydrocele, which is quantitative and minimally invasive and yields good outcomes. Further study is warranted to verify its potential value in clinical practice.
