To the Editor,
We read with interest the article of de Assis et al. regarding the effects of Prostatic Artery Embolization (PAE) on the elasticity of hyperplastic prostatic tissue . The authors utilized a dedicated sono-elastographic technique (shear wave elastography—SWE) to quantitatively evaluate the elasticity of the prostate before and after PAE for the treatment of benign prostatic hyperplasia (BPH). They demonstrated a significant post-therapeutic reduction in prostatic stiffness, thus providing a new insight into the mechanisms of improvement in the dynamic component of BPH by PAE.
Taking advantage of this letter, we would like to briefly describe our initial experience in the same field and to compare our results with those of the original works of de Assis et al. We utilized strain elastography (SE), which is a less sophisticated but more widely available sono-elastographic technique, compared to SWE. SE is based on the analysis of tissue deformation caused by a mechanical...
