Dr Png Keng Siang
Dr Png Keng Siang is a United States fellowship trained robotic surgeon who received his urology Specialist board certification from Singapore. He was the first Singaporean Urologist to complete a minimally invasive surgery fellowship in the US dedicated to robotic surgery and laparoscopy accredited by the Endourological Society at the prestigious Indiana University School of Medicine, where he worked with Past President of the Society of Urological Robotic Surgeons, Professor Chandru Sundaram. Currently, he is Senior Consultant Urologist and Robotic Surgeon at the Urology Centre in FeM Surgery. Before entering private practice, he was:
Adjunct Assistant Professor, Yong Loo Lin School of Medicine
Director of NHG Urology Residency Programme
Chairman of TTSH Robotics Review Committee
Director of TTSH PEARL Private Services
Director of TTSH Robotic Urological Surgery Fellowship Programme
Versatile minimally invasive surgeon
Dr Png is a versatile surgeon who can perform a wide range of minimally invasive procedures. He is adept in both standard key-hole laparoscopy and robot-assisted surgery, customising each patient’s unique scenario in offering the most appropriate minimally invasive approach. He uses innovative techniques such as off-clamp or selective clamping, fluorescent surgery with near-infrared imaging as adjuncts to improve outcomes in his operations.
Dr Png has trained numerous urologists both locally and abroad in robotic surgery. As the Director of Robotic Urological Surgery in TTSH, he has proctored over 150 robotic procedures and trained fellows from India and Nepal. He was invited to kickstart the robotic surgical program in Ho Chi Minh City at Binh Dan Hospital by performing the first 3 robotic urological operations in the history of Vietnam.
Key opinion leader in robotic surgery
Dr Png participates actively in academic and policy developments of robot assisted surgery (RAS) in Singapore. He held the position of Chairman Robotics Review Committee from 2014-2018 in Tan Tock Seng Hospital, overseeing the training and accreditation of all robotic surgeons in the hospital. He grew the RAS program year-on-year, culminating in the installation of a new da Vinci Xi system in 2017. Nationally, he was instrumental in developing the policy of the use of RAS in the public sector over the years. He was member of the Ministry of Health Health Technology Assessment Committee for RAS in 2015, and subsequently appointed as the only urologist in the national workgroup in 2018. He played an advisory role in pre-launch commercial evaluation of novel robotic platforms.
Dr Png has chaired numerous masterclasses in robotic surgery and was the Urology Chairman of the inaugural Asian Summit on Robotic Surgery in 2018. He regularly chairs video sessions on robotic surgery at the American Urological Association (AUA) annual meetings. He has published his experience and written review articles on robotic surgery in peer-reviewed journals and his surgical videos can be found in the AUA Surgical Video Library and the Journal of Videourology. He reviews manuscripts and surgical videos regularly for the Journal of Endourology and Journal of Videourology. He was Founding Life Member and Honorary Secretary of Robotic Surgery Society of Singapore. He is Member of the Society of Urological Robotic Surgeons (USA) and the only urologist in Singapore to sit on its Education Committee. He is also member of the Endourological Society and International Member of the American Urological Association.
Cutting edge diagnosis and treatment for Prostate Cancer
Men with suspected prostate cancer expect a rapid and focused diagnostic process. Dr Png believes in avoiding unnecessary prostate biopsy for men with raised Prostate Specific Antigen(PSA). Through an integrated decision matrix comprising of multiparametric MRI, advanced PSA molecular markers and MRI-targeted fusion biopsy, a customized diagnostic pathway is created for each patient. He co-authored a paper of this approach in a study of over 100 Singaporean men. This approach not only avoided unnecessary biopsy but also improved the accuracy of detecting high-risk cancer. Based on this expertise, he has advised the Ministry of Health in 2018 on the value of using MRI Targeted Prostate Biopsy for men with previous negative biopsy and men on active surveillance for low-risk prostate cancer.
Dr Png has experience in over 200 cases of robot-assisted radical prostatectomy(RARP) for prostate cancer. Learning from Geisinger Medical Centre in the US, he pioneered a RARP pathway consisting of 16 evidence-based best practices. The implementation of this pathway has led to improvement of compliance from 23% to 71%. All his patients therefore undergo this pathway before, during and after RARP. Besides surgery for prostate cancer, Dr Png also treats advanced prostate cancer with standard and novel forms of hormone therapy. He engages a multi-disciplinary team of medical oncologist, radiation oncologist, nuclear medicine specialist to improve survival for these patients.
Full Suite of Treatment for Benign Prostate Hyperplasia (BPH)
Dr Png provides a wide range of treatment solutions for benign conditions of the prostate gland. Most prostate conditions can be treated effectively with modern pharmaceutical treatment, thus avoiding surgery. BPH can also be treated surgically with a suite of surgical options. Besides standard TURP, Dr Png can offer other options such as enucleation or Greenlight laser vaporization, depending on each patient’s prostate size and shape and his medical conditions.
Multi-faceted Treatment of Urinary Stones
Depending on the site and size of urinary stones, the treatment of each patient’s urinary stone must be individualized. Some stones can be simply observed without treatment. Other stones may require one of many surgical options for stone treatment.
Dr Png is an expert in endourological treatment of kidney stones and has performed “live” surgery in Myanmar as part of Asian School of Urology educational series. Dr Png’s special interest is in treating large stones in the upper ureter, using one of 3 possible techniques to treat such challenging stones, and he recently shared his opinions online in the peer-reviewed Urology Times on this topic.
Dr Png's other interest is medical prevention and treatment of stone disease, having trained with Professor Sharon Moe of the Department of Nephrology in Indiana University. His interest was kindled when he was awarded a research grant from the National Kidney Foundation in 2008 while undergoing specialist training. He used the grant to conduct the only local prospective study of metabolic disorders in patients at high risk of urinary stone recurrence, and identified the most common metabolic disorders in this group of patients. Patients with repeated stone attacks can be effectively treated with dietary control and medication to prevent further stone episodes.
Passion in training
Besides his clinical interests, Dr Png has served as Program Director of the National Healthcare Group Urology Residency Programme from 2013 to 2018. During his tenure, he had led the Program to 2 successful accreditation exercises by the Joint Committee of Specialist Training, culminating in his appointment as Member of the JCST Panel of Site Accreditors from 2018 to 2020. He had worked with NTU researchers to study how to improve doctors’ communication skills with patients through novel conversational analysis techniques. Dr Png continues to provide mentorship and training through his academic activities in the Singapore Urological Association and the Robotic Surgery Society of Singapore.
