Ethanolamine oleate as a sclerosant for testicular hydroceles and epididymal cysts

Forty patients with testicular hydroceles and 16 patients with epididymal cysts were treated by tapping and injection of ethanolamine oleate; 97.5% of the hydroceles and 31% of the epididymal cysts were completely cured, 50% of the latter partly cured and 19% failed. About half of the patients experienced pain after treatment. Two patients developed infection. Ultrasonography showed no change in the testicular tissue during the follow-up period. Sclerotherapy with ethanolamine oleate is a rapid and cost-effective modality which can be recommended as primary treatment for hydroceles and for unilocular epididymal cysts, especially in elderly males.
