At Olympus, the general rule for pediatric urology is: "The smallest instrument is the best". With the pediatric urology system, Olympus sets a new benchmark in dimensions as well as in versatility of use. The complete line-up includes a thin percutaneous nephroscope (which also can be used as compact cystoscope), OES Pro resectoscopes and an optical urethrotome. Additionally the pediatric percutaneous nephroscope can also be used as a mini nephroscope for adults. All instruments are constructed of stainless steel is used and all components are autoclavable.
