Abstract
Background
Over the last few years the number of flexible ureterorenoscopies, used for renal stone treatment, has risen steadily. This was associated with an increase in costs for maintenance and repair of the fragile ureterorenoscopes used. To overcome this problem single-use devices have been introduced to the market. The aim of this study was to assess surgical outcome and workability for LithoVue™, a single-use flexible ureterorenoscope.
Methods
We retrospectively analyzed all flexible ureterorenoscopies performed at our department between January and October 2017. We included a total of 108 interventions for renal stone therapy, all performed using the single-use device LithoVue™. We assessed patients’ characteristics including stone size, count and location. We evaluated the surgical outcome, analyzing stone-free rates, reintervention rates, complication rates, as well as surgery time. Learning curve for single-use ureterorenoscopes was evaluated by comparing the surgical outcome between residents and consultants.
Results
The average time needed per intervention was 52,31 min ± 28,11. In 77 out of 108 (71,30%) patients we were able to remove all stones by a single intervention. In 8 patients (7,41%) intra- or postoperative complications occurred, none of which was graded higher than Clavien-Dindo III B. We did not find any statistical differences comparing the surgical outcome between residents and consultants. No technical difficulties occurred during surgery.
Conclusion
Single-use flexible ureterorenoscopes provide decent working properties resulting in good surgical outcome. Furthermore, they are proven to be easy to handle even for unexperienced surgeons, making them a feasible choice for high volume academic centers.
