An observational study in Urologic Injuries, Disorder of Urinary Stent and Kidney Calculi, sponsored by University of British Columbia. Status unknown at 1 site in Canada. Open to participants aged 19 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2022-05-17.

The aim of this study is to identify the root cause for the significant discolouration of Boston Scientific Percuflex based stents.
The aim of this study is to identify the root cause for the significant discolouration of Boston Scientific Percuflex based stents observed in some patients, particularly those from Japan. We will also test and compare them to stents from Canadian patients. Furthermore, we will determine whether the discolouration promotes bacterial adhesion and/or encrustation of the stent.
Patient with indwelling ureteral stent due to urologic indication.
Exclusion Criteria:
Patients with existing indwelling ureteral stent, no additional treatment
stent encrustation
Conditioning film components and encrustation
Time frame: at stent removal
characterize the components that discolour the Percuflex material
Time frame: bench top testing of stents
Bacterial Adhesion, Colonization, and Biofilm formation
Stent pieces from the stent that has been in the patient will be exposed to bacteria and artificial urine to mimic ureter environment in order to find information on: bacterial adhesion, colonization and biofilm formation
Time frame: at 4, 24, and 48 hours post stent removal
