- BWALE-24: Beautiful view of ureter after Tm-Fiber lithotripsy of cystine stone. Full of small white bubbles (the typical one after laser treatment of Cystine stone. See BWALE-16 & T&TV12): like thousands of PEARLS!
00:00 - BWALE-12: For Excellent dusting with Laser: Low Energy & Long Pulse Duration. Fix Frequency Low or High if you want to go Slow(for more precision) or Fast. Keep minimal Distance between Stone Surface and Fiber’s Tip & Respect the same Speed when you are moving at Stone surface
00:00 - BWALE-7: LECURS. Lithotripsy Endoscopically Controlled by URS. Perfect control of each SW efficacy. Constant irrigation for optimal SW transmission. Possible basketing &Laser at the same time. No risk for Flexible-URS if using Single-Use URS. ESWL is not dead, we still need it!!!
00:00 - T&TV32: “F&B”. When stone fragment is around the corner, difficult to catch with basket. Remember: Irrigation is excellent to move stone from one point to another1. Using Syringe /Manual pump: move stone by flushing: Assistant must be ready to catch it when passing through basket
00:00 - BN105:Today with HighPowerLaser(HoYAG 100-150W&TFL60W)we face more&more UreteralLesion(Stenosis!) Our responsibility as KOL-Experts&LaserCompany is to RECOMMEND“SAFE SETTINGS” forPatient¬“OptimalOnes”for max.EFFICIENCY.Please pay attention toURETER.Use LowPower&LowFrequency🙏
- T&TV3: When placing a stiff guidewire into the ureter: if Ureteral Orifice opens like a «Tent», you have a good chance to place UAS(especially small-10/12Fr). But If ureteral orifice stays small &narrow : no need to try, think about Sheathless Technique or pre-stent the patient
00:00 - BWALE-20: Another beautiful intra-renal view. All the calyces on the same line, like a perfect alignment of planets.
00:00 - T&TV61: Incision of infundibulum. If you cannot reach the stone (especially in the lower pole), while you are in maximum deflection: the infundibulum must then be incised. With a Thulium-Fiber laser: 1J-10Hz-ShortPulse (HPP-500W). Benefits: precision and bloodless
00:00 - Pic#8: So lucky we are treating stones in human. Anatomy looks so simple (2-3 major calix 8-12 minor) compared to the Pyelo-Caliceal system of seal: full of calices and renal papilla!!! Cow are not bad too…😊😊😊
- BN107: To all of you who love EndoUrology & Urinary Stones.Don't delay &ask COLOPLAST for this superb book.Magnificent photos of the most beautiful stones from my personal collection and amazing comments from the 60 most renowned KOLs in the world in endoUrology. LIMITED EDITION!
- T&TV63: Duplicate System. When you are searching for the ureteral orifice of the upper pole (usually below the one for the lower pyelocaliceal system), don’t forget that sometime you will not find it into the bladder but in the urethra… look carefully!
00:00 - BWALE-29: Fornix Rupture. This natural jonction between kidney parenchyma and collecting system is so fragile… Can not resist with High Pressure. It cracks so easily and then bleeds. Need definitively a good system to record Intra-Renal Pressure…. Coming soon, stay tuned.
