@EmaMarPa @DrParimalGharia @JEndourology @YAUEndourology @TFL_URO_APIS @CAU_URO @ResidentesCAU @eau_yuo @young_endosoc The closer the tip is, the more reflected light hits back. The higher the gap between the stone and the tip the higher loss of energy in the water. The optimal distance is a kind of compromise. P.S. Classical teaching neglects the role of bubble in photothermal effect of Ho:YAG.

@ryansteinbergmd @JodiAntonelli @thomaschi8 @KSternAZ @DrDAgarwal @amy_krambeck @SorensenMathew @rajatjain35 @UrologyRDN @ChadTracyMD I haven't seen such a stone in my practice. Could be an error if automatic analysis was done because the stone was wet. I'd prefer to see the list of most similar spectra and pick the most probable but not necessarily one with the highest correlation.

@DrParimalGharia @usioffice @drnanjappa @Endo_Society @PEARLSendouro @PETRAurogroup @AmerUrological @Uroweb @ResidentesAEU @Endo_Sec_Eua Probably two mechanisms were responsible. The first one is trisilicate magnesium therapy as antacids and secondly hypercaciuria and/or hyperoxaluria responsible for COM/COD admixtures. For confirmation we should see the surface and section of the stone.

@sbinhamrii @PETRAurogroup @PEARLSendouro I personally don't like when patients sneeze, caughs or snores during operation thus I prefer GA.

Today, I was invited to my daugherts elementary school to talk about my profession. You should see the amazement in the eyes of first and second graders when they saw kidney stones with their own eyes. Priceless!

Just a beautiful COD crystal.

Cystine stones. Type Va in Daudon classification. Despite low density in NCCT (here avg. 700 HU) they are extremly hard as may be seen. They may be mixed with other compounds - in this case COD.

@selcukorkmaz Great explanation!

@jrseltzer So ammonium urate crystals have birefringent characteristics under polarized light with visible Maltese crosses?
