Hamidi N, et al. – In this study, the alterations in cavernous tissue elasticity by elastography in patients who underwent radical prostatectomy with or without neurovascular bundle preservation were investigated. It was noted that preservation of the neurovascular bundle in at least one side mediates lower elasticity scores, better International Index of Erectile Function scores, and penile lengths. Preliminary outcomes of the penile elastography studies are promising for prediction of erectile functions and cavernous tissue fibrosis.
