To investigate the prevalence and risk factors of urinary tract infection (UTI) one year following sub-midurethral sling (SMUS) incontinence surgery in a university affiliated medical center in southern Israel.
A retrospective cohort study was conducted to identify and characterize patients who suffered UTI within a year following SMUS surgery. The study population comprised of all patients who underwent a SMUS surgery between the years 2014 and 2015. Demographic and clinical data were retrieved from the patients' medical records, and a comparison between patients with and without a positive urine culture was performed.
During the study period, there were 178 SMUS surgeries. Urine culture positive UTI was noted in 21% (38 patients) within the first year following surgery. The mean age and BMI of patients complicated with UTI was 64.8 and 29.1, respectively. The most common pathogen found in urine culture was E. coli that accounted for 55% of all UTIs. When comparing patients with and without UTI, no significant difference was noted in the pre- and intra-operative characteristics. However, duration of hospitalization and readmissions in the first year following surgery, were significantly associated with the risk of UTI (p < 0.026 and p < 0.003, respectively).
Approximately one in every five women undergoing a SMUS operation in our population will suffer from UTI within a year from surgery. A significant association was found between the duration of hospitalization and readmissions in the first postoperative year and suffering from UTI.
