Risk factors leading to midurethral sling revision: a multicenter case-control study

Introduction and hypothesis
To determine risk factors for sling revision after midurethral sling (MUS) placement.
This multicenter case-control study included patients who underwent MUS placement and subsequent revision secondary to voiding dysfunction from January 1999–2007 from nine Urogynecology centers across the USA. Direct logistic regression analysis was used to determine which diagnostic variables predicted sling revision.
Of the patients, 197 met the study criteria. Patient demographics, urodynamic findings, and operative differences did not increase the risk for sling revision. Risk factors for sling revision did include: pre-existing voiding symptoms (OR 2.76, 95% CI 1.32–5.79; p = 0.004) retropubic sling type (OR = 2.28, 95% CI 1.08–4.78; p = 0.04) and concurrent surgery (OR = 4.88, 95% CI 2.16–11.05; p < 0.001)
This study determined that pre-existing obstructive voiding symptoms, retropubic sling type, and concurrent surgery at the time of sling placement are risk factors for sling revision.
