30 Day Morbidity and Reoperation Following Midurethral Sling: Analysis of 8,772 Cases Using a National Prospective Database

To determine 30 day complications, risk of readmission, and reoperation for midurethral slings(MUS).

The National Surgical Quality Improvement Program database from 2006-2013 was queried for MUS alone by excluding concurrent reconstructive, urologic, or gynecologic procedures. We assessed baseline characteristics, 30-day perioperative outcomes and 30-day readmission. Logistic regression analysis identified risk factors for the frequent complications.

8772 women underwent MUS, of which 3830 (43.7%) and 4942 (56.3%) were performed by urologists and gynecologists, respectively. Patients of urologists were older, had higher frailty, and were more likely diabetic (all p<0.05). Patients of gynecologists were more likely to have resident involvement compared to urologists (16.4% vs. 11.2%,p<0.001). Mean operative time was shorter for urologists compared to gynecologists (35.6 +/- 29.2 vs 38.1 +/- 34.3 min,p<0.001). The overall 30-day rate of any complication was 3.52%. Urinary tract infection (UTI) occurred in 2.2% vs. 3.5% of the urologic and gynecologic patients, respectively (p=0.001). After adjusting for frailty, BMI, steroid use, age, operative time and residency involvement, gynecologic performed surgery incurred an increased risk of UTI (OR:1.67,95%CI:1.27-2.19;p=0.001). Sixty five (0.90%) patients were readmitted within 30 days, most commonly due to urinary symptoms. Sling revision for urinary obstruction occurred in 15 patients; 10 underwent repair of the bladder, urethra, or vagina.

To our knowledge, we present the largest American cohort of MUS 30-day outcomes to date stratified by specialty of performing surgeon. Overall, morbidity is low. UTI is the most common complication, and occurs at increased frequency for patients of gynecologists.
