Steve Biko Academic Hospital Performs First Cryoablation in South Africa’s Public Health Sector
Pretoria, 17 January 2026 — Steve Biko Academic Hospital has entered a new chapter in South African public healthcare after successfully performing its first cryoablation procedure, a milestone that positions the institution as the first public hospital in the country to introduce this advanced, minimally invasive treatment.
The procedure, carried out at the Pretoria-based academic hospital, represents a significant step forward in the provision of specialised and super-specialised care within the Gauteng Department of Health.Cryoablation is a medical technique that destroys abnormal tissue, including cancer, by freezing it at extremely low temperatures, and is widely regarded internationally as a precise, patient-friendly alternative to conventional surgery for selected tumours.
The pioneering case was performed by specialist radiologists Prof Van Der Walt, Dr Rodney Maseko and Dr Riaan Potgieter, working under the leadership of Professor Zarina Lockhat. They were joined by urologists Dr Guy Gaudji and Dr Raymond Campbell, under the leadership of Professor Kgomotso Mathabe, reflecting a multidisciplinary approach that is central to modern interventional medicine.
Cryoablation involves the percutaneous insertion of thin probes into the target tissue under image guidance, typically using CT or ultrasound. Once correctly positioned, the probes release bursts of argon gas that rapidly lower temperatures to below –40°C, forming a clearly visible “ice ball” that envelops and destroys abnormal cells while sparing surrounding healthy structures. The ability to visualise the treatment zone in real time allows clinicians to achieve exceptional accuracy, particularly when lesions are located near critical organs or blood vessels.
Compared with open surgery, cryoablation offers substantial benefits for patients, including reduced pain, minimal blood loss, shorter hospital stays, and faster recovery times. These advantages are especially important in public healthcare settings, where reducing complications and length of admission can significantly ease pressure on already stretched resources.
Adding a further layer of innovation to the procedure was the use of remote international expertise. Dr Matthias Feurstner (MD, EBIR-IO, EMBA), an experienced interventional radiologist based in Austria, served as the proctor for the case. Through real-time virtual supervision, he guided the local team throughout the procedure. Dr Potgieter wore Google Smart Glasses, enabling live visual communication with the off-site proctor an advanced application of digital health technology that underscores the growing role of global collaboration in modern medicine.
Hospital leadership has described the achievement as a testament to the skill, dedication, and forward-thinking mindset of the clinical teams involved. It also reflects sustained strategic investment by the Gauteng Department of Health in high-impact technologies that expand access to world-class care within the public sector.
Beyond the walls of Steve Biko Academic Hospital, the successful introduction of cryoablation carries broader significance. It signals a shift towards more equitable access to cutting-edge treatments traditionally limited to private healthcare, and reinforces the role of academic public hospitals as drivers of innovation, training, and research.
As South Africa’s public health system continues to confront complex disease burdens and resource constraints, milestones such as this demonstrate how targeted investment, multidisciplinary expertise, and intelligent use of technology can translate into tangible improvements in patient care.
