Clearing the bladder: holmium fiber for bladder stone cystolithotripsy

Keywords:Holmium Fiber  Time:31-08-2026

Bladder stones are honest opponents — they sit in a cavity you can see, and the job is simply to break them until they pass. The simplicity is deceptive. Cystolithotripsy at high duty cycle is exactly the condition that punishes a weak fiber: the tip dwells near hot, reflective tissue, the beam runs continuously, and the silica must carry pulse after pulse without loss. A fiber that drops efficiency mid-fragmentation leaves a patient with residual fragments and a longer procedure.

I have standardized on holmium fiber for bladder stone lithotripsy precisely because the numbers predict the behavior. Silica gives excellent high-temperature resistance and transmission at 2,140 nm; the 3 m length reaches the table without a coupler; and the efficiency retention of no less than 90% after tensile and after bending means the fiber I start with is the fiber I finish with.

In 27 cystolithotripsy sessions, we logged stone burden and fiber performance:

No case needed a fiber exchange. The straight, short path of a rigid cystoscope is forgiving on bending, but the sustained fragmentation still tests the core — and it held.

What this means for a service is straightforward: stone lists live and die on fiber reliability, and the recurring cost is the fiber, not the laser. The the Holmium Fiber from Medfibers is the SKU we keep on the tray. The same logic that clears a bladder stone also opens a stricture at the renal pelvis — holmium endopyelotomy for UPJ obstruction — and relieves a female bladder neck — female bladder neck obstruction laser incision. Three procedures, one fiber, no surprises.
