Objective: To determine 30-day complications, risk of readmission, and reoperation for midurethral slings (MUS).
Methods: The National Surgical Quality Improvement Program database from 2006 to 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.
Results: There were 8772 women who 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 < .05). Patients of gynecologists were more likely to have resident involvement compared to urologists (16.4% vs 11.2%, P < .001). Mean operative time was shorter for urologists compared to gynecologists (35.6 ± 29.2 minutes vs 38.1 ± 34.3 minutes, P < .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=.001). After adjusting for frailty, body mass index, 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=.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.
Conclusion: 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.
