OBJECTIVEThe aim of the study was to clarify which baseline, operative, and postoperative factors are associated with the development and recurrence of urinary tract infection (UTI) after midurethral sling (MUS).
METHODSThis is a retrospective analysis of patients who underwent a MUS from February 2010 to April 2014 within a single practice with 2 surgeons. Distribution of perioperative factors with relation to 6-week UTI occurrence (primary outcome) and recurrent UTI (secondary outcome) within a year after surgery were analyzed using Studentʼs t test and χ test. Then, independent risk factors were determined using multiple logistic regression. A P value of less than 0.05 defined statistical significance.
RESULTSFrom the 500 patients who underwent MUS, 79 (15.8%) developed a UTI within 6 weeks of surgery and 5.8% had recurrent UTI within a year. Looking at the independent effects, patients with a history of recurrent UTI and voiding dysfunction requiring catheterization more than 24 hours were at a higher risk of developing UTI within 6 weeks after surgery. In addition, having a history of recurrent UTI, asymptomatic bacteriuria, and postoperative UTI within 6 weeks after surgery were significantly associated with postoperative recurrent UTI.
CONCLUSIONSIn this study, we identified baseline and postoperative characteristics that are associated with greater risk of UTI within 6 weeks and recurrent UTI after MUS. These factors can be potentially modified or useful in counseling patients on personalized risks and benefits of the surgical procedure.
