Can contrast-enhanced ultrasound increase or predict the success rate of testicular sperm aspiration in patients with azoospermia?

American Journal of Roentgenology Apr 26, 2019

Xue H, et al. - In patients with azoospermia, researchers ascertained if contrast-enhanced ultrasound (CEUS) perfusion measurements obtained before testicular sperm aspiration (TESA) could improve or predict sperm retrieval (SR) outcomes of TESA. Seventy patients with azoospermia underwent testes CEUS within 10 days before TESA between May 2017 and January 2018. According to findings, CEUS-guided TESA with cognitive fusion cannot yield improved TESA SR results in NOA patients, possibly due to an imprecise correlation between biopsy sites and the main area of perfusion analyzed by CEUS, however, quantitative CEUS characteristics can be useful predictors of SR success.
