Autologous mid-urethral fascial sling for stress urinary incontinence: Long term outcomes

Abstract

There has been an increasing interest in mesh-free surgical options for Stress Urinary Incontinence (SUI). Traditionally rectus fascia autologous slings were placed at the bladder neck but more recently they are positioned at the mid-urethra (aMUS). The long-term outcomes for these patients are described. A retrospective analysis of aMUS patients between 2009-2014 by a single surgeon for primary SUI was performed. All patients were evaluated preoperatively with urodynamics. Patient reported outcomes were collected via postal questionnaire using the ICIQ-UI short-form questionnaire, 7-point Global Impression of Improvement score, questions on pad usage, self-catheterisation, overactive bladder treatment and re-operation rates. Results included 31 patients (response rate 63.8%). The median age was 49 years and median BMI was 27. Twenty-seven per cent (27%) of patients had stress predominant mixed urinary incontinence pre-operatively. Median length of follow up was 8 years (5- 11); 60% of patients were dry and pad-free. Seventy-seven per cent (77%) found the surgery led to “much improvement” or “very much improvement” in quality of life. Thirteen per cent (13%) of patients reported a deterioration in quality of life. The median ICIQ-UI short form score was 5.5. 16.7% were taking medication and 1 patient received botulinum toxin therapy for overactive bladder symptoms. All these patients had mixed urinary incontinence on preoperative urodynamics. The re-operation rate was 13.3%. One patient was selfcatheterising. Three out of 31 (10%) had experienced pelvic pain, with 2 out of 31 (6%) experiencing dyspareunia. AMUS shows good long-term continence outcomes and is associated with low rates of de-novo overactive bladder symptoms and voiding dysfunction.
