[Advances in ultrasound techniques for the diagnosis and staging of prostate cancer. Elastography, Doppler ultrasound, ultrasound contrast media, ultrasound quantification media and MRI fusion].

Objectives: Transrectal ultrasound-guided prostate biopsy remains the gold standard in the diagnosis of prostate cancer. Various Ultrasound modalities have been proposed to increase the cancer detection rate. Our purpose is to evaluate each of these methods , and to present its current literature and clinical utility.

Lessons learned from the CROES percutaneous nephrolithotomy global study.

Purpose: The purpose of the study was to give an overview of the data derived from the CROES PCNL Global Study published previously in 25 articles.

Methods: A comprehensive overview of the outcome of the CROES PCNL Global Study was made, analysed and compared with the current literature and guidelines.

Results: Percutaneous nephrolithotomy (PCNL) was predominately performed in prone position.

[Diagnosis of upper urinary tract tumors. A pending challenge].

Early diagnosis of upper urinary tract tumors is not easy. The development of endoscopic equipment has expanded the group of patients candidates for minimally invasive treatment. Only by providing accurate tumor staging and grading can clinicians decide which patients should be offered conservative therapies.

How well tolerated is supine percutaneous nephrolithotomy?

Purpose Of Review: Supine percutaneous nephrolithotomy (PCNL) has been described in 1988 and several modifications followed since. Despite claimed benefits, supine PCNL is still neglected by the majority of urologists. Lack of experience and the fear of complications are possible explanations for the resistance to supine positioning.

[Single-session extracorporeal shock wave lithotripsy for urinary calculi: factors predicting success after three weeks of follow-up].

Introduction: The aim of this study was to identify predictive factors of success following a single-session of shock wave lithotripsy (SWL) at 3 weeks of follow-up in our center.

Material And Methods: The medical records of 116 patients with solitary urinary calculi who underwent single-session SWL in our department between October 2007 and August 2009 were reviewed. All preoperative unenhanced computed axial tomographies were reviewed by two radiologists blinded to clinical outcome.
