Dr Arianayagam has built a reputation as one of New South Wales’ leading urologic surgeons, with a strong focus on cancer surgery and advanced, minimally invasive techniques.
With extensive training across robotic, laparoscopic and open procedures, he brings a versatile and highly specialised approach to treating a wide range of urological conditions.
At the forefront of his practice is robotic surgery, where precision and control are key. Having performed over 1200 robotic procedures, Dr Arianayagam is among the most experienced robotic surgeons in NSW. This level of expertise allows for highly refined surgical outcomes, particularly in complex urologic cancer cases, where accuracy can make a significant difference in recovery and long-term health.
Alongside robotic techniques, he is also highly skilled in laparoscopic surgery, offering patients minimally invasive options that typically result in reduced recovery times, less pain, and smaller incisions. His proficiency across both laparoscopic and open surgery ensures that each patient receives the most appropriate treatment tailored to their specific condition.
A major focus of his work is urologic cancer surgery, where early detection and precise intervention are critical. Within this space, focal therapy is emerging as an important treatment option for selected patients, particularly those with localised prostate cancer. Focal therapy targets only the cancerous area of the prostate, rather than removing the entire gland, aiming to preserve healthy tissue and reduce the risk of side effects such as incontinence or erectile dysfunction. It reflects a shift towards more personalised, less invasive cancer care—something Dr Arianayagam integrates into his practice where suitable.
Beyond cancer care, he also provides comprehensive general urology and stone surgery services, managing conditions such as kidney stones, urinary tract issues and other common urological concerns. His broad expertise allows him to support patients through both routine and complex cases with confidence and care.
With a commitment to precision, innovation and patient-focused outcomes, Dr Arianayagam continues to lead in delivering advanced urological care, combining surgical expertise with evolving treatment options like focal therapy to provide patients with the best possible outcomes.
