customized diagnosis and treatment for prostate cancer

Dr Png believes in avoiding unnecessary prostate biopsy for men with raised Prostate Specific Antigen(PSA). Through an integrated decision matrix, a customized diagnostic pathway is created for each patient. This approach includes:

  • Multiparametric MRI
  • Advanced PSA molecular markers
  • MRI-targeted fusion biopsy

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.

targeted prostate biopsies

At the Urology Centre at FeM Surgery, Dr Png performs targeted prostate biopsies via 2 approaches. Based on each patient’s unique characteristics, Dr Png will formulate a customised treatment approach.

transrectal approach

The transrectal approach is for patients who require standard targeted biopsy under local anaesthesia or sedation.

transperineal approach

The transperineal approach, done through the skin, has almost no infection risk. This is reserved for patients who require multiple cores of biopsy.

MRI-targeted robotic prostate biopsy

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. All his RARP patients therefore undergo this pathway. Find out about robotic surgery for prostate cancer here 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 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 transurethral resection of prostate (TURP), Dr Png can offer other options such as prostate enucleation, Greenlight laser vaporization, Rezum water vapour therapy or microwave thermodilatation, 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.

He has published his experience and written review articles on robotic surgery in peer-reviewed journals and his surgical videos are published in the AUA Surgical Video Library and the Journal of Videourology.

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 worked with NTU researchers on 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 and serves as examiners at Urology Specialty examinations.
