Sclerotherapy with tetracycline solution for hydrocele.

A study of sclerotherapy for hydrocele using different concentrations (10%, 5%, 2.5%) for tetracycline solution was done on 24 patients, 23 patients were cured. The effectiveness of sclerotherapy was the same for the three groups of patients with use of each different concentration of the solution. Pain was the only adverse effect. Nonspecific cellular foreign body reaction and fibrin strand proliferation were observed in the hydrocele fluid after this procedure. We consider sclerotherapy for hydrocele with tetracycline solution safe and the procedure of choice for patients in whom surgery or anesthesia is contraindicated, for patients who refuse surgery, and for economic reasons.
