Does the Zamenix robot really perform the surgery by itself?

Goldman's Zamenix robot assists the surgeon's precise maneuvers, supporting safe, accurate surgery grounded in human experience and judgment. It does not operate in place of the surgeon — it is a state-of-the-art tool that raises the surgeon's capability another level.

Any risk of side effects or complications after Zamenix surgery?

The non-invasive approach means low risk of bleeding and infection and a lower complication rate.

Is there a waiting area for family members during surgery, or a space for patients to rest?

Yes. Goldman Urology Clinic has inpatient rooms and a family waiting room, so you can rest comfortably before and after your procedure. Family can wait there during surgery, and afterward we guide patients and family to the clinic's lounge areas to rest.

Goldman Urology: all about Zamenix, from Goldman Urology

VIEW

It is an advanced flexible endoscopic surgical robot system that maximizes
surgical precision, stability, and efficiency through AI-based features.

Based on features such as respiratory compensation, stone size guidance, and path saving,
it uses an ultra-small endoscope and artificial intelligence to automatically locate kidney stones without any incision and remove them.

SINCE 2002, the hub of AI smart healthcare

Goldman: the advanced AI kidney stone surgical robot, Zamenix

Goldman, always a step ahead, performs surgery with the advanced AI kidney stone surgical robot Zamenix.

With university-hospital-grade equipment and the expertise of its medical team, Goldman is always first down the new path.
