Milestones in endoscope design for minimally invasive urologic surgery: the sentinel role of a pioneer

Abstract

Endoscopically based techniques have revolutionized the entire field of surgical specialties over the past 50 years. Currently, minimal access surgery is commonplace for considerable segments of surgical procedures across specialty lines. Central to this revolution, and arguably foremost in its impact on the development of minimally invasive endoscopic surgery, was the development of the rod-lens optical system by Professor Harold H. Hopkins and the almost simultaneous development of the fiberoptic cold-light light source by Karl Storz. It was George Berci who acted as the catalyst in bringing these two men together in the early 1960s, and from that meeting ensued one of the most successful cooperations in the design of endoscopic equipment. Innovative surgeons quickly recognized the enormous potential of these inventions, and in this context, George Berci's work and vision provided the hallmark events leading to the clinical applications from which surgeons and their patients so greatly benefit currently. In urology, Berci's early work has been recognized as a sentinel event bringing endoscopic endoluminal surgery from the lower urinary tract (urethra, bladder, prostate) to the upper urinary tract (ureter, kidney), and eventually to extraluminal laparoendoscopic surgery. This work has been recognized by the Journal of Urology as a "milestone in urology" leading to the clinical application in the field of endoscopic surgery currently referred to as endourology. In this article, the current state-of-the-art urologic surgery for the management of stone disease, urologic tumors, and anatomic abnormalities is presented, which to a great extent has its roots in George Berci's contributions to the field of innovative endoscope design.
