PURPOSE: We report varicocele prevalence in adolescents. Surgical treatment has been proposed in adolescents with relevant testicular disproportion to avoid fertility problems in adulthood. We prospectively analyzed the testicular volume variation in adolescents with varicocele and hypoplastic testis. MATERIALS AND METHODS: In a 2-year period we selected 54 consecutive pediatric patients with a median age of 14.5 years (range 13 to 16) who had left varicocele using certain criteria, including testicular volume discrepancy greater than 20%, no previous inguinal-testicular surgery and no symptoms. Adolescents were divided into 2 groups, including 27 who underwent surgical correction with lymphatic sparing microsurgical varicocelectomy (intervention) and 27 who were only observed (control). After surgery or at first observation patients were evaluated clinically and by ultrasound at 3, 6 and 12 months. Testicular volume was estimated by the prolate ellipsoid formula. RESULTS: We noted significant improvement in testicular volume with less than 20% disparity between the 2 gonads in 23 patients (85.2%) in the intervention group and in 8 controls (29.6%). Two recurrences (7.4%) were reported in the intervention group, each in an adolescent with increased testicular volume. CONCLUSIONS: Our study confirms significantly increased testicular volume in many surgically treated boys and shows that physiological catch-up growth occurs in adolescents with varicocele without treatment. Considering critically results in each group, in select cases clinical and ultrasound followup is indicated before intervention due to a possible spontaneous decrease in testicular asymmetry. Further histopathological studies are needed to identify the relationship between testicular hypoplasia, irreversible damage and future fertility problems to determine which adolescents should be treated.
