At Olympus, the general rule for paediatric urology is: "The smallest instrument is the best". With the paediatric urology system, Olympus sets a new benchmark in channel diameter 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 paediatric percutaneous nephroscope can also be used as a mini nephroscope for adults. For all instruments stainless steel is used and all parts are autoclavable.
