Do you trust clinical studies to definitively guide your choice between similar medical treatment options?
A clinical study of 178 adults compared the efficacy of Holmium:YAG and thulium fiber lasers for breaking up kidney stones. Both laser methods achieved similar stone-free rates and improved patient quality of life.
Why it matters
This research provides clinical evidence that both common laser platforms effectively treat stones, offering reassurance for patients concerned about surgical options. Understanding these comparable outcomes helps streamline treatment expectations for those managing kidney stones.
In a randomized trial of 178 adults, researchers found no significant difference in stone-free rates between the Holmium:YAG and thulium fiber laser (TFL) groups. Stone clearance was verified via CT imaging 6 to 12 weeks post-surgery.
The players
The Journal of Urology
A peer-reviewed publication serving as the official journal of the American Urological Association.
The details
Surgeons performed the procedures using a flexible ureteroscope equipped with a 200-µm laser. The lasers work by fragmenting stones within the kidney into smaller pieces, or dust, that can be passed or removed. Researchers observed no meaningful difference in complication rates between the two laser types, and both groups saw significant improvements in patient-reported quality of life.
Timeline
Patients underwent kidney stone treatment between 2023 and 2025.
Results were published in The Journal of Urology on September 24, 2026.
Health Landscape
This study compares established Holmium:YAG technology against the newer thulium fiber laser in the standard practice of ureteroscopic laser lithotripsy. It clarifies the performance of these tools in an era of rapidly evolving surgical instrumentation for stone disease.
If you are scheduled for kidney stone surgery, these findings suggest that your surgeon may achieve similar results using either laser platform. It is worth discussing with your doctor which specific technology is available at your surgical center and how it factors into your recovery plan.
The takeaway
Both Holmium:YAG and thulium fiber lasers effectively clear stones between 5 mm and 20 mm with similar success. Patients should consult with their urologist about the specific surgical approach recommended for their stone size and anatomy.
