Postoperative urinary tract infections (UTIs) following single-dose intraoperative antibiotic prophylaxis in...

The records of 196 women who underwent colposuspension for genuine stress incontinence at the Leicester General Hospital, England, between June 1991 and May 1996 were reviewed for evidence of urinary tract infection (UTI). Variables analyzed include age, type of antibiotic, timing of a positive culture, organism(s) responsible and antibiotic sensitivity. Forty-six patients (23.47%) developed urinary infection; of these, 42 had received single-dose antibiotic prophylaxis with suprapubic catheterization. Thirty-two (76%) of those who developed UTI received augmentin (amoxycillin and clavulanic acid), whereas 10 (24%) were given cefuroxime and metronidazole. Positive cultures were obtained between postoperative days 3 and 28, with a mean of 9.6 days, and 81% occurred after the 7th day. Coliform organisms were responsible for nearly 70% of the infections. UTI is still common after colposuspension, despite single-dose antibiotic prophylaxis. Further studies looking at longer or alternative courses of antibiotics or clean intermittent self-catheterization are essential to establish the best way of curbing UTI in urogynecology patients.
