Abstract

Background

Robotic systems are increasingly utilised to improve clinical outcomes in prostate interventions.

Methods

We enroled 20 patients to verify the clinical feasibility of transrectal ultrasound (TRUS)-guided robot-assisted prostate biopsy (PBx). For each patient, controlled trials of systematic 12-core PBx were initially conducted manually using a biopsy gun, followed by a 3-core cognitive fusion targeted biopsy performed by the hand-held robot.

Results

The targeting errors for robot-assisted biopsy and freehand biopsy were 3.71 ± 1.41 mm and 3.94 ± 1.49 mm, respectively. Their cancer core rates were 19.1% and 12.6%, and the average duration of each biopsy was 6.94 min and 1.62 min, respectively.

Conclusions

The robot's sampling success rate was lower than that of freehand with a biopsy gun in the clinical trial. However, robot-assisted PBx has shown improved cancer core rate, slightly enhanced surgical accuracy, and the capability to reach clinically significant tumours' 5 mm error range, all demonstrating its clinical value.

期刊介绍： The International Journal of Medical Robotics and Computer Assisted Surgery provides a cross-disciplinary platform for presenting the latest developments in robotics and computer assisted technologies for medical applications. The journal publishes cutting-edge papers and expert reviews, complemented by commentaries, correspondence and conference highlights that stimulate discussion and exchange of ideas. Areas of interest include robotic surgery aids and systems, operative planning tools, medical imaging and visualisation, simulation and navigation, virtual reality, intuitive command and control systems, haptics and sensor technologies. In addition to research and surgical planning studies, the journal welcomes papers detailing clinical trials and applications of computer-assisted workflows and robotic systems in neurosurgery, urology, paediatric, orthopaedic, craniofacial, cardiovascular, thoraco-abdominal, musculoskeletal and visceral surgery. Articles providing critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies, commenting on ease of use, or addressing surgical education and training issues are also encouraged. The journal aims to foster a community that encompasses medical practitioners, researchers, and engineers and computer scientists developing robotic systems and computational tools in academic and commercial environments, with the intention of promoting and developing these exciting areas of medical technology.
