Antegrade scrotal sclerotherapy is a simple and easy technique for the treatment of varicocele. The success rate varies between 87 % and 95 %. The initial reflux grade and the number of collateral vessels of the spermatic vein are the most important factors to predict the outcome of the technique. The postoperative complication rate is about 7 % and the common ones are scrotal hematoma and epididymo-orchitis of slight severity. Testicular athrophy is a rare event (0.6 %). This technique offers a considerable cost reduction compared to other therapeutic options currently available for varicocele.
