ABSTRACT

The author reviews the computer and robotic tools available to urologists to help in diagnosis and technical procedures. The first part concerns the contribution of robotics and presents several systems at various stages of development (laboratory prototypes, systems under validation or marketed systems). The second part describes image fusion tools and navigation systems currently under development or evaluation. Several studies on computerized simulation of urological procedures are also presented.

Motivation & Objective

• To evaluate the state of the art in computer- and robot-assisted urological surgery as of 2007.
• To identify and categorize robotic systems in development, validation, or commercial use.
• To analyze image fusion and navigation systems for intraoperative guidance in urological procedures.
• To examine the role of computerized simulation in training and planning for urological interventions.
• To assess the integration of advanced imaging and robotics to enhance surgical precision and safety.

Proposed method

• Systematic review of robotic platforms used in urology, including laboratory prototypes, systems under clinical validation, and commercially available systems.
• Analysis of image fusion techniques combining preoperative imaging (e.g., CT, MRI) with real-time intraoperative data for surgical navigation.
