ABSTRACT
CONTEXT Thulium fiber laser (TFL) emerged as a competitor of holmiumyttrium aluminum garnet (HoYAG) laser for the treatment of urinary stones. OBJECTIVE:
To compare the efficacy between HoYAG and TFL for laser lithotripsy of renal and ureteral stones. EVIDENCE ACQUISITION A literature search was conducted using PubMed/Medline, Embase, and Web of Science databases to identify reports published until May 2023. The Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed to identify eligible studies. The primary outcome was to compare the stone-free rate (SFR) between HoYAG and TFL for laser lithotripsy. EVIDENCESYNTHESIS:
Eleven studies met our inclusion criteria, and data from 1286 and 880 patients who underwent, respectively, HoYAG and TFL laser lithotripsy were reviewed. Most studies included ureteroscopy (URS) and retrograde intrarenal surgeries as procedures, two included percutaneous nephrolithotomy, and one included URS exclusively. Only two studies reported results in pediatric patients. TFL was associated with a higher SFR (odds ratio [OR] 1.84, 95% confidence interval [CI] 1.06-3.20; p = 0.031) when no residual fragment is considered, but not when SFR refers to the presence of fragments <3 mm (OR 2.48, 95% CI 0.98-6.29; p = 0.055) or when only HoYAG with MOSES is considered (p = 0.068). According to the stones' location, TFL was associated with higher SFRs than HoYAG for renal (OR 3.14, 95% CI 1.69-5.86; p < 0.001) but not for ureteral (p = 0.8) stones. TFL was associated with a lower intraoperative complication rate (OR 0.34, 95% CI 0.19-0.63; p < 0.001). No difference was found in major (p = 0.4) or overall (p = 0.4) complication rate, operative time (p = 0.051), and laser time (p = 0.9).CONCLUSIONS:
TFL is a promising laser for the treatment of urinary stones with some advantages over HoYAG. Further high-quality studies are needed to confirm these findings and optimize the surgical settings. PATIENTSUMMARY:
The use of thulium fiber laser rather than holmiumyttrium aluminum garnet permits to reach a higher stone-free rate in stones located in the kidney rather than in the ureter.Palavras-chave
