A Randomized Controlled Trial to Improve the Therapeutic Effect of Robot-assisted Radical Prostatectomy (RARP) Using Indocyanine Green Fluorescence Imaging

In robot-assisted radical prostatectomy, indocyanine green fluorescent solution is injected through the urethra, and the position and structure of the urethra are observed by using the fluorescence imaging equipment that comes with the device. Guided by real-time fluorescence imaging, the urethra is precisely dissected and severed in front of the bladder neck. Through this improved operation, the bladder neck is protected, the neck injury that is common in conventional surgical operations is reduced, and the reconstructive surgical operations necessary after loss are reduced, and the surgical efficiency is improved. By protecting the bladder neck, the sphincter is better preserved, postoperative urinary incontinence is reduced, and the surgical outcome is improved.
