Durability of Flexible Ureteroscopes and Causes of Infection During Flexible Ureterorenoscopy

Kidney Stones Clinical Trial

Official title:
Durability of Flexible Ureteroscopes and Causes of Infection During Flexible Ureterorenoscopy

Clinical Trial Summary

This is an observational study in which data on consecutive patients who undergo ureterorenoscopy with the use of a flexible ureterorenoscope are collected. In total 20 new ureteroscopes are usedfrom Olympus andfrom Storz) to study the durability of the ureteroscopes and the possible microbiological load.

Clinical Trial Description

This is an observational study in which data on consecutive patients who undergo ureterorenoscopy with the use of a flexible ureterorenoscope are collected. In total 6 new ureteroscopes are used (3 from Olympus and 3 from Storz) to study the durability of the ureteroscopes and the possible microbiological load.

Before the procedure is started the endoscope is tested for its microbiological load in two different ways:1. Shake the tip of the flexible ureterorenoscope 5 seconds in a sterile container filled with 10 cc of NaCl 0.9% 2. Flush the working channel of the ureterorenoscope with 10 cc of NaCl 0.9% and collect the sample in a sterile container.

After the procedure is finished, the endoscope is tested for its microbiological load in two different ways:

1. Shake the tip of the flexible ureterorenoscope 5 seconds in a sterile container filled with 10 cc of NaCl 0.9% 2. Flush the working channel of the ureterorenoscope with 10 cc of NaCl 0.9% and collect the sample in a sterile container.

Transfer all samples to the lab as soon as possible but at least within four hours after collecting the samples.

As for the clinical efficacy during each procedure a detailed questionnaire about the use of each ureteroscope is filled out. This includes the ease of use making mention on quality of the image, torque, flexibility and durability.

Data will be collected through electronic case report forms (eCFRs), with use of an online Data Management system (DMS). ;
