[QUOTE="madman, post: 201672, member: 13851"] [B]Abstract Background:[/B] Varicoceles have been considered for a long time as potentially correctable causes for male infertility, even though the correlation of this condition with infertility and sperm damage is still debated. [B]Objective:[/B] To present a summary of the evidence evaluation for imaging varicoceles, to underline the need for a standardized examination technique and for a unique classification, and to focus on pitfalls in image interpretation. [B]Methods:[/B] Based on the evidence of the literature, the current role of US imaging for varicoceles has been reported and illustrated, with emphasis on examination technique, classification, and pitfalls. [B]Results:[/B] US is the imaging modality of choice. It is widely used in Europe, while in other countries clinical classification of varicoceles is considered sufficient to manage the patient. A number of US classifications exist for varicoceles, in which the exam is performed in different ways. [B]Discussion:[/B] An effort towards standardization is mandatory, since lack of standardization contributes to the confusion of the available literature, and has a negative impact on the understanding of the role itself of imaging in patients with varicoceles. [B]Conclusion:[/B] The use of the Sarteschi/Liguori classification for varicoceles is recommended since it is the most complete and widely used US scoring system available today. [B][I]*Tubular extratesticular structures resembling varicoceles, either at palpation or at US, should be identified and correctly characterized.[/I] Introduction [I][U]Varicoceles are abnormal dilatations of the pampiniform plexus with reflux of venous blood flow[/U].
