Diagnosis of prostate cancer by analyzing oxidative stress in human seminal plasma: developing unsophisticated tools for noninvasive prostate cancer diagnosis.

Prostate-specific antigen blood testing has improved early detection of prostate cancer (PCa); however, PCa mortality has not decreased accordingly and a prostate biopsy is still required for a definitive diagnosis. Proteomic biomarker screening in easily available body fluids such as seminal plasma is now increasingly being proposed as a solution to improve PCa detection and prognosis. PCa cells typically produce high levels of reactive oxygen species (ROS).

[Extra peritoneal laparoscopic radical prostatectomy. Preliminary results].

Objectives: Presentation of our initial experience with the practice of the laparoscopic radical prostatectomy through the extraperitoneal access (ELRP). We describe the proceeding and its technical difficulties, time consumption and complications.

Methods: From January to May 2005 we have indicated 17 ELRP in our institution.
