Profiles of the bacterial community in short-term indwelling urinary catheters by duration of catheterization and subsequent urinary tract infection.

Background: Urinary catheterization, even of short duration, increases the risk of subsequent urinary tract infection (UTI). Whether the bacteria found on the surface of catheters placed for <3 days are associated with UTI risk is unknown.

Methods: We screened the biofilms found on the extraluminal surface of 127 catheters placed for <3 days in women undergoing elective gynecologic surgery, using targeted quantitative polymerase chain reaction and an untargeted 16S rRNA taxonomic screen.

Cranberry juice capsules and urinary tract infection after surgery: results of a randomized trial.

Objective: The risk of urinary tract infection (UTI) among women undergoing elective gynecological surgery during which a catheter is placed is high: 10-64% following catheter removal. We conducted the first randomized, double-blind, placebo-controlled trial of the therapeutic efficacy of cranberry juice capsules in preventing UTI after surgery.

Study Design: We recruited patients from a single hospital between August 2011 and January 2013.
