Comparison of Antimicrobial Coated Ureteral Stents With Non-coated Stents

A Randomized Controlled Trial Comparing Antimicrobial Coated (Silver Sulfadiazine) Ureteral Stents With Non-coated Stents

This study will be conducted to compare the efficacy of antimicrobial coated ureteral stent with non-coated stents in prevention of UTI in patients with ureteral stents

The efficacy of antimicrobial coated of ureteral stent with silver sulphadiazine in prevention of UTI in patients with ureteral stents will be studied by comparining the results of urine and stent cultures with patients who had non-coated ureteral stents. The impact of antimicrobeal stent coating on patients' quality of life will be evaluated with comparing the scores of ureteral stent symptom questionnaire between both groups.

Inclusion Criteria:

• Patients who will undergo ureteral stent placement

Exclusion Criteria:

• Patients allergic to sulpha containing medications
• Ureteral stent insertion for infected hydronephrosis
• Patients who developed septic complications requiring antibiotic treatment after stent placement
• Patients who need bilateral stents
• Patients with chronic kidney disease grade IV and V (GFR <30ml/min)
• Immunocompromised patients as those with malignancy or organ transplantation.
