Single-incision slings for the treatment of stress urinary incontinence: efficacy and adverse effects at 10-year follow-up.

Single-incision slings are not considered a first-choice surgical treatment owing to a lack of data about long-term outcomes. We aimed to assess the long-term results of urinary incontinence treatment after single-incision sling implantation at 10 years' follow-up and to investigate possible deterioration over time.

This retrospective study analyzed women with subjective and urodynamically proven stress urinary incontinence who underwent single-incision sling procedure. The objective cure rate was assessed with a 300-ml stress test. The subjective cure rate was determined by the Patient Global Impression of Improvement (PGI-I) questionnaire. International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) questionnaire scores and self-answered patient-satisfaction scales were collected to assess symptom severity. Findings were compared with short-term outcomes in the same patients, available through our previous database, in order to detect possible outcome deterioration over time.

The records of 60 patients were analyzed. Nine patients (15%) were lost to follow-up. A total of 51 patients completed the evaluation, with a mean follow-up of 10.3 ± 0.7 years. Objective and subjective cure resulted 86.3% and 88.2% respectively. Mean PGI-I scores and ICIQ-SF were 1.5 ± 1.0 and 3.2 ± 4.8 respectively. Patients' satisfaction scored 8.6 ± 2.6 out of 10. No long-term complications occurred. Comparison of short-term (2.6 ± 1.4 years after surgery) and long-term follow-up did not show a significant deterioration of outcome over time.

Single-incision slings were shown to be a procedure with a great efficacy and safety profile at very long-term follow-up. Cure rates and functional outcomes did not show any deterioration over time compared with short-term results.
