Urinary tract infection and antibiotic use around ureteral stent insertion for urolithiasis.

Urolithiasis is the main indication for a ureteral JJ stent. Our aim was to determine the incidence of urinary tract infections (UTIs) after a JJ stent for urolithiasis, with an emphasis on antibiotic use. Prospective, multicenter, cohort study over a 4-month period including all of the patients with urolithiasis requiring JJ stent insertion.

Risk Factors for Unnecessary Antibiotic Therapy: A Major Role for Clinical Management.
