The prediction of urinary calculi fragmentation duration under the holmium laser pulses

The results of settlement-experimental definition (prediction) of urinary stones fragmentation duration by the holmium laser impulses with the wavelength of 2.1 microns and energy from 0.8 to 1.6 J are presented in the paper. The obtained analytical expressions allow to estimate the duration of urinary stone complete fraction on the basis of its volume and radiological density as well as on its location, comprising the auxiliary manipulations time, and to predict lithotripsy operation duration regarding this data
