The KARL STORZ uretero-renoscope FLEX-X2S offers improved visibility* thanks to its double fiber capacity. This optical enhancement, in conjunction with already proven properties, provides an overview of the renal calyx system – as every detail counts. With a sheath circumference of 7.5 Fr., the FLEX-X2S uretero-renoscope enables access to some of the most challenging areas of the anatomy – such as the lower pole calyces of the kidney – and offers a full dual 270° deflection with an easy-to-use single lever control. The sheath is extremely torsion-resistant and thus allows navigation of the upper urinary tract. The integrated Laserite ceramic insulation protects the instrument from thermal damage at the distal tip.
