A retrospective comparison between transrectal and transperineal prostate biopsy in the detection of prostate cancer.

Background: The aim of this study was to analyze the differences between TRUSguided transrectal prostate biopsy (TR) and transperineal prostate biopsy (TP) in the diagnosis of prostate cancer. The two biopsy methods were evaluated in terms of diagnostic sensitivity and of early and late complications.

Methods: This retrospective study was realized through the review of clinical records of 219 men that received a prostate biopsy between 2004 and 2014.

[Pain in urology: pathophysiological aspects of pain and chronicity.].

Chronic pain has been traditionally defined by pain duration, but this approach has limited empirical support and does not account for chronic pain multidimensionality. Defining chronic pain solely by duration is based on the view that acute pain signals potential tissue damage, whereas chronic pain results from central sensitization in which pain is sustained after nociceptive inputs have diminished. Chronic urological pain is a prevalent condition, which can represent a major challenge to health care providers due to its complex aetiology and poor response to therapy.

A brief historical survey of "Peyronie's disease".

Introduction: Historians of medicine and urology, sexology, and andrology in particular maintain that many other physicians, surgeons, anatomists, and pathologists have already described "Peyronie's disease" some centuries before the author after whom it has been called, François Gigot de La Peyronie (1678-1747).

Aim: To perform a brief historical survey of Peyronie's disease. Methods.

Molecular biology and the staging of prostate cancer.

Cancer of the prostate is still controlled or cured by surgery, radiotherapy, and hormone therapy. The present criteria of complication and prediction are criticized more and more for not being sufficiently reliable, due to the high heterogeneity of prostatic cells. The continuing discoveries of intra- and extracellular mechanisms of the molecular informational network, which allow the continuity or discontinuity of the cell's life, are also related to prostate cancer.
