PURPOSE: We performed intraoperative antegrade venography to assess the prevalence of internal spermatic venous malformations in adolescents with varicocele. MATERIALS AND METHODS: During a 2-year period 58 adolescent males with visible or palpable varicocele underwent antegrade venography before varicocele surgery. Antegrade venography was performed through a scrotal incision. A vein within the pampiniform plexus was cannulated and up to 1.75 mg/kg iohexol 300 mg/ml was injected to outline the entire length of the internal spermatic vein. The radiographs were reviewed and classified according to Bähren and Murray criteria. RESULTS: Of the patients 43 (74.1%) demonstrated parallel duplications (Murray classification type P) of the internal spermatic vein. This rate is higher than the 2% reported based on retrograde venography. Of the patients with parallel duplications 21 (48.8%) showed duplications arising superior to the iliac crest (subtype A) and 22 (51.2%) had a combination of proximal duplications (subtypes B and C). Ten patients (17.2%) had a single internal spermatic vein, 2 (3.4%) had lumbar collaterals and 3 (5.2%) had renal collaterals. CONCLUSIONS: Parallel duplication of the internal spermatic vein is a common finding on antegrade venography. The various levels of duplication need to be identified before treatment of varicocele to maximize the success of the procedure.
