The usefulness of elastography in the evaluation and management of adult men with varicocele: A systematic review.
Objective: To review the role of elastography in the evaluation and decision-making of adult, infertile men with varicocele.
Methods: A systematic search using the terms (Elastography) AND (Varicocele), (Stiffness) AND (Varicocele), (Elastography) AND (Male infertility) was performed in Pubmed/Medline. Studies reporting a) elastographic characteristics in varicocele-bearing comparing to normal testicles, and b) the correlation of elastography with varicocele grading, parameters of spermatogenesis, and outcomes of varicocele treatment were selected. Exclusion criteria were animal, adolescents, abstracts, and non-English language studies.
Results: In total, 453 articles were identified; 11 eligible studies were selected. Several modalities were used (shear wave elastography, strain elastography, quasistatic ultrasound elastography, acoustic radiation force impulse). Varicocele-bearing testicles have significantly different stiffness and elasticity in comparison to normal and non-varicocele testicles. Although not in full agreement, elastography readings are correlated with semen parameters. Conflicting results were reported regarding grading as most of the studies failed to demonstrate a significant correlation. Shear wave elastography showed a significant correlation with the improvement in semen parameters after varicocelectomy, but the association with pregnancy rates is unknown. Finally, no studies were identified comparing elastography with other modalities.
Conclusions: Elastography can detect changes in the architecture of varicocele-bearing testicles. Although the role of the modality in grading is uncertain, elastography showed a meaningful correlation with spermatogenesis parameters. Importantly, elastography readings could predict the improvement in semen parameters after varicocelectomy which is useful in terms of decision-making in infertile men with varicocele.

期刊介绍：
The Arab Journal of Urology is a peer-reviewed journal that strives to provide a high standard of research and clinical material to the widest possible urological community worldwide. The journal encompasses all aspects of urology including: urological oncology, urological reconstructive surgery, urodynamics, female urology, pediatric urology, endourology, transplantation, erectile dysfunction, and urinary infections and inflammations. The journal provides reviews, original articles, editorials, surgical techniques, cases reports and correspondence. Urologists, oncologists, pathologists, radiologists and scientists are invited to submit their contributions to make the Arab Journal of Urology a viable international forum for the practical, timely and state-of-the-art clinical urology and basic urological research.
