    Abstract:
    Idiopathic varicocele is nowadays accepted as a "social disease" for both its high incidence among young men and its affecting male fertility. Screening is thus required for young people and, above all, early and definitive treatment. We have evaluated the effectiveness of percutaneous sclerotherapy, which has become a standard procedure, in spite of its recent introduction in interventional radiology. One hundred and thirty-nine percutaneous occlusions were performed on 147 patients with varicocele using a sclerosing agent--polidocanol--and stainless steel coils. The failure rate of percutaneous treatment was about 12%. Complications never required hospitalization or surgery; recurrence rate is 3.66%. The patients were followed 3, 6, 12 and 24 months by US and Doppler to survey recurrences, and sperm analysis to estimate the clinical results of percutaneous therapy in infertile patients. Statistical analysis with linear regression of data from spermiograms showed constant improvement in sperm count, sperm motility percentage, and sperm morphology percentage. Fertility index improvement was similar to that of surgical ligation. The radiation dose received by the patient is negligible. Percutaneous therapy represent thus the treatment of choice in case of varicocele: compared with surgery, it offers similar clinical results and a lower recurrence rate, and it can be performed on an outpatient basis. Surgery should be performed only when anatomic variants make percutaneous treatment not feasible.
