As laser platforms evolve, comparative assessment of their thermal profiles is increasingly important. This study presents the first comparative evaluation of temperature generation using three contemporary systems: pulsed thulium: YAG (Tm: YAG; Dornier Thulio), thulium fiber laser (TFL; Olympus SOLTIVE), holmium: YAG with pulse modulation (MOSES 2.0; Boston Scientific MOSES 2.0) using manufacturer-recommended dusting settings in an ex vivo porcine kidney model. Eighteen porcine kidney\u2013ureter units were implanted with renal pelvic temperature probes and Bego stones. Specimens were randomized to one of three lithotripsy systems (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20096 per group; one MOSES specimen excluded). A flexible ureteroscope was introduced via a 35\u00a0cm 10\/12Fr ureteral access sheath, followed by 10\u00a0min of near-continuous dusting using 200\u00a0\u03bcm fibers (0.3\u00a0J\/50Hz for TFL and Tm: YAG; 0.3\u00a0J\/60 Hz for MOSES 2.0). Pressurized irrigation was maintained at 100-150mmHg. Outcomes included absolute temperature change, total energy delivered, and temperature increase normalized to energy (\u00b0C\/kJ). The greatest mean temperature rise was observed with TFL (8.13\u2009\u00b1\u20091.96\u00a0\u00b0C), followed by pulsed Tm: YAG (4.12\u2009\u00b1\u20091.26\u00a0\u00b0C) and MOSES 2.0 (3.32\u2009\u00b1\u20091.84\u00a0\u00b0C). TFL demonstrated significantly greater heat generation than Tm: YAG (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.0031) and MOSES 2.0 (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.0010). When temperature was adjusted for energy delivery, TFL (1.09\u2009\u00b1\u20090.30\u00a0\u00b0C\/kJ) surpassed both Tm: YAG (0.47\u2009\u00b1\u20090.14\u00a0\u00b0C\/kJ;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.0007) and MOSES 2.0 (0.31\u2009\u00b1\u20090.18\u00a0\u00b0C\/kJ;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.0001). No specimen exceeded temperatures of 43\u00a0\u00b0C. In this ex vivo setting, TFL was associated with higher heat generation relative to both pulsed Tm: YAG and MOSES 2.0; however, all systems remained below accepted thermal safety thresholds under the tested conditions (43\u00a0\u00b0C).\n                  <\/jats:p>","DOI":"10.1007\/s00240-026-01957-8","type":"journal-article","created":{"date-parts":[[2026,3,2]],"date-time":"2026-03-02T08:52:19Z","timestamp":1772441539000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Comparative evaluation of temperature generation during laser lithotripsy: thulium fiber laser, pulsed thulium: YAG, and holmium: YAG with pulse modulation in an ex vivo porcine kidney model"],"prefix":"10.1007","volume":"54","author":[{"given":"Bruce","family":"Gao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tyler","family":"Sheetz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aymon","family":"Ali","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luke","family":"Griffiths","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harel","family":"Sims","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helen","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiffany R.","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yezan","family":"Hadidi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seyedamirvala","family":"Saadat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jamie","family":"Finegan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vi","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sirpi","family":"Nackeeran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seth K.","family":"Bechis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roshan M.","family":"Patel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,3,2]]},"reference":[{"key":"1957_CR1","doi-asserted-by":"publisher","first-page":"45","DOI":"10.1007\/s11934-018-0807-y","volume":"19","author":"P Kronenberg","year":"2018","unstructured":"Kronenberg P, Somani B (2018) Advances in Lasers for the Treatment of Stones - A Systematic Review.
