How Does Laser Fiber Diameter Affect a Surgeon’s Work?

The core diameter of a laser fiber is selected according to the surgical access route, the instruments being used, and the clinical objective. The VPG Surgical Fiber Reusable S range for Urolase thulium fiber lasers includes reusable laser fibers with core diameters from 150 to 940 µm.

When are 150–200 µm fibers used?

Small-diameter fibers are used in retrograde intrarenal surgery (RIRS) and procedures performed through flexible ureterorenoscopes when a narrow, minimally invasive access route is required.

The product range includes 150 µm and 200 µm fiber instruments.

Which procedures are suitable for a 365 µm fiber?

The 365 µm fiber is a versatile option for stone fragmentation. It can be used for contact laser lithotripsy, including RIRS, as well as for percutaneous and mini-percutaneous procedures.

When is a 550 µm fiber selected?

The 550 µm fiber is used for soft-tissue procedures and with larger-diameter instruments. Potential applications include the surgical treatment of benign prostatic hyperplasia (BPH), bladder stone treatment, and procedures performed t hrough larger percutaneous access tracts.

What is a 940 µm fiber used for?

The 940 µm fiber is primarily selected for procedures involving prostate tissue, particularly prostate vaporization in patients with BPH.

There is no universally “best” fiber diameter. The appropriate choice depends on the surgical access route, the instruments being used, and the intended application—lithotripsy or soft-tissue treatment.
