The present study was carried out with an aim to perform a prospective study to establish the role of sodium tetradecyl sulfate (3 %) (STDS) as a safe and effective sclerosant in the management of primary hydrocele. Sclerotherapy was performed with 3 % STDS on an outdoor basis. The amount of sclerosant injected depended on the amount of fluid drained. All patients were given prophylactic antibiotics. Patients were clinically reassessed at 1 week, 1 month, 3 months, and 6 months and earlier if complications occur. The data were analyzed using Statistical Package for Social Sciences Version 15.0. The data have been represented as frequencies and percentages. Chi-square test was used to compare the data. A total of 57 patients with primary vaginal hydrocele gave consent for being enrolled in the study. The age of patients ranged from 18 to 65 years with a mean age of 35.72±13.18 years. The success rate at the end of the study was observed to be 84.2 %. As regards patient satisfaction, in present study, in a limited time period of follow up, all the patients who had a successful procedure were satisfied. Overall, sclerotherapy was observed to be a relatively cost-effective (including both direct and indirect costs) procedure with low complications, high satisfaction, and a high success rate within the limited period of follow-up.
