Abstract
BACKGROUND AND OBJECTIVE
Until a few years ago, a midurethral sling was considered the gold standard for the treatment of female stress urinary incontinence (SUI) after failure of conservative therapies. However, criticisms regarding the rate of mesh exposure and lack of long-term efficacy have led to reconsideration of other surgical procedures. Our aim was to investigate long-term subjective and objective outcomes after injection of Macroplastique, a urethral bulking agent.
METHODS
We prospectively enrolled all consecutive women complaining of pure SUI symptoms with urodynamically proven SUI who received a Macroplastique injection. We investigated patient-reported subjective outcomes using International Consultation on Incontinence Questionnaire-Short Form, Urogenital Distress Inventory, Patient Global Impression of Improvement, and Visual Analog Scale (VAS) questionnaires, and the cough stress test to assess objective outcomes. Adverse events were recorded during follow-up.
KEY FINDINGS AND LIMITATIONS
At 10 yr after Macroplastique injection, the objective cure rate was 56% and 71% of patients reported that they were satisfied. Long-term data revealed no significant decline in subjective or objective cure rates. No serious complications were reported. Study limitations include the small sample size and the lack of pad tests and bladder diaries for postoperative evaluations.
CONCLUSIONS AND CLINICAL IMPLICATIONS
Our study shows that Macroplastique injection can be an effective and safe option for the treatment of female SUI in the long term, even when used in the first-line setting.
PATIENT SUMMARY
We evaluated outcomes for women with stress urinary incontinence (SUI) who were treated with an injection of Macroplastique gel into the wall of the urethra to prevent leakage of urine. We found that this is a safe option for treatment of female SUI that is effective in the long term.
