Objectives: To evaluate long-term effects, complications and satisfaction among patients treated with AdVance™ and AdVance™ XP slings (AS) at a Norwegian specialist care hospital., Materials and Methods: Patients who had an AS implanted due to stress urinary incontinence (SUI) 2009-2016 were identified retrospectively. Demographic and perioperative data were extracted from electronic patient files. We did a patient-reported outcome measure (PROM) survey with the Expanded Prostate Cancer Index Composite (EPIC-26) urinary domain and a Satisfaction Questionnaire (SQ) 2018-2020. Cure was defined as use of ≤1 pad/day., Results: The AS was implanted in 165 patients, mainly due to mild to moderate SUI (median leakage 112 g, range 13-589 g/24 h). Preoperative urodynamics showed mild detrusor overactivity (DO) in 11 patients. At 6-week follow-up, 148 patients (90%) were cured. The most common complication was urinary retention ( N  = 38), transient in 32 patients (range 1-42 days). Two patients were later operated with division of the sling due to persistent retention. During clinical follow-up of up to 12 years, 27 patients were reoperated due to persistent/recurrent incontinence. The PROM survey was sent to 125 patients and 115 (92%) replied at median 73 (20-134) months postoperatively. Ninety-one (79%) used ≤1 pads/day, 97 (85%) were satisfied, one patient-reported pain. Regression analyses showed that failure (>1 pad/day) was significantly associated with a higher amount of leakage preoperatively and at the 6-week follow-up. Total cure rate in the complete cohort was 64% at median 73 (20-134) months follow-up., Conclusions: The AS shows good and persistent long-term results in patients with mild to moderate SUI. The only identified risk factor for long-term failure was higher amount of leakage preoperatively. The incidence of high body mass index (BMI), DO and previous radiotherapy was low and not significantly associated with failure but is still considered risk factors., Competing Interests: R.T.B. reports no conflicts of interest.
