Microbiological Analysis of Urine Cultures in Women after Pelvic Reconstructive Surgery.

Background/Aims: The rate of urinary tract infection (UTI) after pelvic reconstructive surgery ranges from 9 to 48% and the most common uropathogen is Escherichia coli ( E. coli ). The aim of the study is to identify the predominant uro-pathogen from urine cultures in women undergoing pelvic reconstructive surgery.

Methods: A retrospective review was conducted on women who underwent pelvic reconstructive surgery at a tertiary care center from July 2013 to June 2015. Data was collected from each postoperative visit to evaluate urinary tract symptoms, culture results and treatment in the 3-month postoperative interval.

Results: There were 880 cases reviewed (mean age of 59.6 years) during the study period. The most common organism in positive cultures was E. coli after surgery. The total UTI rate was 11.3%. Patients discharged with a Foley catheter had a UTI rate of 65.6% (p = 0.003). Diabetes, neurologic disease, tobacco use, recurrent UTIs and breast or gynecologic cancers had no significant association with UTI after surgery.

Conclusion: The most common organism identified is E. coli . Almost 12% of patients will develop a UTI after pelvic reconstructive surgery. The results of this study can influence management of lower urinary tract symptoms in the postoperative period.
