[A simple alternative technic in the treatment of idiopathic hydrocele in adults: vaginal "fenestration"].

The author describes a new, simple technique for the treatment of idiopathic hydrocele according to a "fenestration" procedure designed to correct the imbalance of intravaginal hydrostatic exchanges. The operation consists of initially hemming separately the deep fibrous layer and the parietal leaflet of the tunica vaginalis to form the margins of the "window", which is then applied by its fibrous layer to the dartos, continuous with the subcutaneous connective tissue, a site of rich lymphatic drainage. In a series of 108 patients treated by this technique since September 1982, with a follow-up of 6 years, the anatomical and functional results were excellent in 98 cases (90.7%), moderate in 6 cases (5.5%) and poor in 4 cases (3.7%). Compared to classical techniques, the fenestrated opening of the tunica vaginalis with preservation of the tunica vaginalis and limited opening of the serosa, preserves the testicular support and the protective role of the serosa on the testis. Lastly, suture of the margins of the window to the dartos, by facilitating deep lymphatic drainage towards the superficial connective tissue, reconstitutes a physiological equilibrium in the constant exchanges of intravaginal serous fluids. Experience has demonstrated the anatomical and functional efficacy and reliability of this extremely simple procedure, which is essentially indicated in adult patients with idiopathic hydrocele and a healthy tunica vaginalis.
