Predictors of prolonged hospitalization and perioperative complications following mid-urethral sling mesh removal

To assess preoperative and perioperative characteristics associated with increased length of stay and major complications after mid-urethral sling mesh removal.

We performed an IRB-approved retrospective analysis of patients who underwent mid-urethral sling mesh removal. Demographic data and baseline surgical characteristics were collected. Operative reports and hospital/clinic notes were reviewed for complications which were categorized using the Clavien-Dindo Classification scheme. Length of stay was deemed abnormal if greater than 1 day. Complications were assessed using multivariate regression analysis.

A total of 468 patients were identified as having undergone mid-urethral sling mesh removal. Mean age was 56 (± 11.1). 431 patients had either retropubic or transobturator slings. 241 patients underwent retropubic or groin exploration as a part of their mesh removal. A prolonged length of stay was noted in 73 patients (15.6%) and 13 patients (2.8%) experienced a Clavien Grade 3 complication. Pre-operative narcotic/benzodiazepine use, concomitant surgical procedure, bladder injury, increased ASA class, and major complications had an increased odds of a prolonged length of stay. Patients who experienced a bladder injury, groin/suprapubic incision, and estimated blood loss of over 400 mL had an increased odds of Clavien Grade 3 complications.

Patient characteristics and perioperative factors are associated with increased length of stay and major complications after mid-urethral sling mesh removal.
