About

Christopher Wai Sam Cheng is a pioneering urological surgeon and researcher whose work has significantly advanced the field of robotic-assisted surgery, particularly in the treatment of prostate cancer. His key research areas include surgical robotics, the learning curve for robotic procedures, and functional outcomes following prostatectomy. Cheng’s most impactful contributions center on demonstrating that a structured, team-based approach can dramatically reduce the learning curve for robot-assisted laparoscopic radical prostatectomy (RALP), a finding that has helped institutions worldwide adopt this complex technology more safely and efficiently. His seminal 2006 paper on this topic has garnered 42 citations, while his broader work on equipment and technology in surgical robotics has been cited 53 times. Cheng also made important contributions to understanding the natural history of voiding function after RALP (26 citations), providing critical insights into patient recovery and quality of life. Additionally, his work on deformable registration for integrating MRI/MRSI information into TRUS-guided prostate biopsy (3 citations) laid groundwork for more precise cancer detection. Through these efforts, Cheng has helped shape modern urological practice, making robotic surgery more accessible and improving outcomes for prostate cancer patients.
