However, image distortion often occurs during laser lithotripsy owing to acoustic wave production. We sought to compare image distortion using different laser power settings and distances from the laser fiber tip to the scope for the Super Pulsed Thulium Fiber (SPTF) laser and high-power Holmium:YAG (Ho:YAG) laser.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>\n                      Ureteroscopy was simulated using a silicon kidney-ureter-bladder model fitted with a 12F\/14F access sheath and the Lithovue\u2122 (Boston Scientific), disposable digital flexible ureteroscope. At defined laser parameters (10, 20, 30 and 40 W, short pulse), a 200-\u03bcm laser fiber was slowly retracted toward the tip of the ureteroscope during laser activation. Image distortion was identified, and distance from the laser tip to the scope tip was determined.

Image distortion occurs further from the ureteroscope with Ho:YAG laser than with SPTF fibers at the same laser settings. In clinical practice, the tip of the laser fiber should be kept further away from the tip of the scope during ureteroscopy as the power increases as well as when utilizing the Ho:YAG system compared with the SPTF laser platform. The SPTF laser may have a better safety profile in terms of potential scope damage.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/end.2022.0195","type":"journal-article","created":{"date-parts":[[2022,9,15]],"date-time":"2022-09-15T05:37:54Z","timestamp":1663220274000},"page":"99-104","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Image Distortion During Flexible Ureteroscopy: A Laboratory Model Comparing Super Pulsed Thulium Fiber Laser\n                    <i>vs<\/i>\n                    High-Power Ho:YAG Laser"],"prefix":"10.1177","volume":"37","author":[{"given":"Caleb S.","family":"Miller","sequence":"first","affiliation":[{"name":"Department of Urology, The University of Kansas Health System, Kansas City, Kansas, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3525-7557","authenticated-orcid":false,"given":"Bristol B.","family":"Whiles","sequence":"additional","affiliation":[{"name":"Department of Urology, The University of Kansas Health System, Kansas City, Kansas, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1038-1375","authenticated-orcid":false,"given":"Willian E.","family":"Ito","sequence":"additional","affiliation":[{"name":"Department of Urology, The University of Kansas Health System, Kansas City, Kansas, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edward","family":"Machen","sequence":"additional","affiliation":[{"name":"University of Kansas, School of Medicine, Kansas City, Kansas, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey A.","family":"Thompson","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, University of Kansas Medical Center, Kansas City, Kansas, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David A.","family":"Duchene","sequence":"additional","affiliation":[{"name":"Department of Urology, The University of Kansas Health System, Kansas City, Kansas, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donald A.","family":"Neff","sequence":"additional","affiliation":[{"name":"Department of Urology, The University of Kansas Health System, Kansas City, Kansas, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wilson R.","family":"Molina","sequence":"additional","affiliation":[{"name":"Department of Urology, The University of Kansas Health System, Kansas City, Kansas, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,1,1]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0022-5347(17)64066-7"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.2147\/RRU.S104229"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.21037\/tau.2019.09.17"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-014-1402-6"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-019-02785-9"},{"issue":"8","key":"e_1_3_4_7_2","first-page":"767","article-title":"SuperPulsed Thulium fiber laser: The ultimate laser for lithotripsy?","volume":"73","author":"Keller EX","year":"2020","unstructured":"Keller EX, , Traxer O.
