MicroPerc® – the miniaturization of percutaneous nephrolithotomy ( PCNL ) taken to the extreme by PolyDiagnost

With the All-Seeing-Needle® in miniaturized form and its offspring MicroPerc®, PolyDiagnost sets the benchmark in minimally invasive percutaneous nephrolithotomy (PCNL ).

PolyDiagnost continues its modular theme with the recent development of MicroPerc® remaining attentive to patient safety and offering all options for percutaneous kidney stone fragmentation. The valuable MicroPerc® optic comes with the proven PolyScope lens system with its field of view of 120 degrees, reflecting peripheral and direct human vision. This allows controlled therapy and a simple scan of the environment at the end of the procedure to check the absence of stones. The absence of any lumen is the basis of highest hygienic standards. Access elements with lumen are provided as sterile disposable product.

However, MicroPerc® is far more than the miniaturization of percutaneous nephrolithotomy. Further applications are currently being tested and will be published shortly.

Investment protection

MicroPerc® can be connected to all conventional endoscopy towers making it easy and economic to expand your toolbox for kidney stone management.


PolyDiagnost offers own cameras, light sources and irrigation pumps,  optimized for use in micro-endoscopy.
