2.  New digital flexible ureteroscopes offer certain advantages by comparison to their predecessors.  We aimed to retrospectively analyze the uretero-renoscopic procedures performed with the Storz Flex-Xc model in order to evaluate its particularities.

3. 558 procedures (510 patients) Ureteral access sheath was used in 82% of the cases II. 96 procedures (90 patients) III. 151 procedures (139 patients) V. 200 procedures (173 patients) IV. 159 procedures (143 patients) I. 62 procedures (55 patients) Still working!

4. The endoscopes were used for 51, 67.1, 107.7, 107.2 and 142.3 hours, respectively. Relocation of the lower pole stones was performed in all cases when it was possible. Major repairs:  Optical system chip failure (first endoscope)  Significant damages of the outer coating (second one)  Severe deterioration of the deflecting mechanism (third and fourth endoscopes)

5. Significant damages of the outer coating (second endoscope) Significant loss of maximal deflection (third endoscope)

6. Flexible Video-Uretero- Renoscopes Storz Flex-XC P.Geavlete, 2013 After 198 procedures!

7.  Storz Flex-Xc seems to be an effective and durable flexible ureteroscope.  We managed to use it in a record number of cases by comparison to the published data. CONCLUSIONSCONCLUSIONS
