Retrograde ureteroscopy and ureterorrenoscopy have become the first-line option for treatment of ureteral and renal stones worldwide with high success rates allied with a low morbidity profile. In this review, we will discuss some key points in ureteroscopy for stone disease, such as the access to upper urinary tract, including balloon and catheter dilation; how to choose and use some disposable devices (hydrophilic versus PTFE guide wires, ureteral catheters, and laser fiber setting); and lastly present and compare different techniques for kidney or ureteral stone treatment (dusting versus basketing).engrestrictedAccessCalculiKidneyLithiasisUreterUreteroscopyholmium-yag lithotripsylaser fragmentation efficiencyureteral drainage stentoptimal power settingsin-vitroflexible ureteroscopyuncomplicated ureteroscopycalculus retropulsionurinary calculipulse-widtharticleCopyright EDIZIONI MINERVA MEDICAUrology & Nephrology1827-1758
