In our experience, even if limited, the high ligation of spermatic vessels is simple, safe and effective, even at long term. Fifty-two boys under went surgical therapy at diagnosis--average age 12,9 y. We did not find recurrences of varicocele. Four boys showed postoperative hydrocele; no one required surgical treatment.
