FlexGuard

- protects flexible ureterorenoscopes against damage by laser fibres
- flexible ureterorenoscopes remain deflected during insertion of the laser fibre
- keeps the stone in focus
- saves costs and time

The fact
For the therapy of stones in lower calices of the kidney the unrestricted mobility of the flexible instruments is required. The mobility of flexible ureterorenoscopes is impaired by laser fibres due to their stiffness and friction inside the working channel. Loading of a deflected ureterorenoscope with an unprotected laser fibre results in severe and costly damage of the instrument’s working channel.

The past
The conflict between mobility of flexible ureterorenoscopes and laser fibres required a 2 step procedure: Localisation and identification of a stone in a lower calyx was performed in a first step with an “empty” working channel. Following the decision for laser fragmentation the flexible ureterorenoscope needed to be straightened again and the laser fibre was forwarded.
