About this trial
To identify the risk factors associated with bacterial colonization of Double-J ureteral stents and to evaluate its clinical implications, including bacteriuria, UTI, antimicrobial resistance, and stent-related symptoms.
Eligibility criteria
Qualifiers
Patients undergoing temporary Double-J ureteral stent insertion.
Stent inserted for a standard urological indication, including ureteric stone disease, ureteral obstruction, postoperative drainage, or ureteral injury repair.
Planned stent removal during the study follow-up period.
Availability for clinical follow-up and specimen collection at insertion and removal.
Disqualifiers
Active urosepsis at the time of stent insertion.
Permanent or intended long-term stenting outside the study framework.
Concomitant nephrostomy tube or urinary diversion that may confound microbiological results.
Known severe immunosuppression or neutropenia if expected to substantially alter colonization risk.
