Predictors of sling revision after mid-urethral sling procedures: a case–control study

摘要: OBJECTIVE To identify patient characteristics and surgical factors predictive of complications requiring mid-urethral sling (MUS) revision/removal. DESIGN Case-control study. SETTING Tertiary academic centre in Canada. POPULATION One hundred seven women undergoing MUS revision/removal between 2005 2016 were matched with 214 controls by date index procedure (2:1 ratio). METHODS Data on obtained via manual electronic paper chart review. Three sets pre-specified simple multivariable logistic regression models fitted to: (1) examine previously reported risk for revision after primary treatment; (2) preoperative predictors revision/removal; (3) associated this outcome adjusting potential confounding factors. MAIN OUTCOME MEASURES Crude adjusted odds ratios (ORs) 95% confidence intervals (95% CIs) RESULTS The median time to was 153 days (interquartile range, IQR 49-432 days). Active smoking status (OR 2.29, CI 1.13-4.63, P = 0.03), having had a previous hysterectomy 3.88, 2.02-7.46, < 0.01), concomitant pelvic organ prolapse surgery at the 2.63, 1.32-5.52, 0.01) independently need Sling type (obturator versus retropubic), method tensioning (to cough over instrument), anaesthetic type, estimated blood loss not analysis presented here. CONCLUSIONS status, hysterectomy, are subsequent TWEETABLE ABSTRACT Risk include smoking, surgery.
