Intérêt du contrôle échographique endorectal en temps réel dans le traitement de l'hypertrophie bénigne de la prostate par vaporisation Laser Greenlight® XPS (180 W)

We report a technical improvement of the Greenlight® XPS prostatectomy by using real time transrectal ultrasonography (TRUS) during the procedure. The TRUS probe lays on a flexible support fastened to the operative table. A wide screen with double display allows the surgeon to control the progress of the procedure with simultaneous ultrasonographic and endoscopic views. The depth of vaporization clearly appears as an hyperechogenic line together with an enlargement of the vaporization area. Real time TRUS monitoring during photovaporization of BPH decreases the learning curve, the risk of prostatic capsule perforation and bleeding, and allows to check the completeness of the procedure.
