Despite the fact that more recent generation randomized sham-managed trials have shown promising results which was a outcome of better understanding of the renal anatomy and improvements in device style, many questions keep on being unanswered Within this field.

g., diagnostic separation of prostatic adenocarcinoma from benign prostatic hyperplasia or from prostatic intraepithelial neoplasia (Grizzle 2001).
