Dr Olivier TRAXER is currently Professor of Urology at the University of Paris 6th (Pierre et Marie Curie) and works in Tenon Hospital (academic hospital). After a training in general urology in Paris, Dr Olivier TRAXER did a research-fellowship at Southwestern Medical School, University of Texas, Dallas-Texas (under the supervision of Professors Charles Y.C PAK and Margaret Sue PEARLE) to subspecialize in Endourology and kidney stone management which represents his main field of interest.
As endo-urologist, his main goal is to improve the knowledge on urinary stone disease and endourology, to optimize the quality of treatment given to patients, and to promote the role of his specialty in that field. Pr Traxer Olivier is responsible in Tenon Hospital-Urology department (University Hospital, University Pierre et Marie Curie Paris-6) of the minimaly invasive surgery section.

Pr Traxer presently works in three directions :
1. Development of an endourology and stone center at Tenon Hospital. Numerous clinical papers have been published on the evaluation and treatment of urolithiasis and new technologies in endourology:
* evaluation of minimally invasive surgery (standard and mini-percutaneous nephrolithotomy, ESWL, flexible ureterorenoscopy, lasers in surgery)
* evaluation of stone disease (studies on medical management of urolithiasis and medical evaluation of stone disease, diet and stone disease)
* evaluation of various disposable (flexible URS, Ureteral access sheath, incrustations of double J stent, lasers…).

More than 130 papers published in the Medline and more than 200 oral and poster presentations in international and national congresses.

2. Participation in International and National educational programs : French Urological College (ECU), European School of Urology (ESU), International Consultation on Stone disease. Organization of practical courses for urologists from France and international countries.

3. Development of a research program on an augmented reality system for percutaneous nephrolithotomy with 3D reconstruction and instant volume measurement of complex renal calculi, preparation for percutaneous nephrolithotomy and real time fusion of 2D fluoroscopic and 3D segmented images. Different awards have been obtained for this project (RSNA meeting Chicago).
