Cross-linked Hyaluronic Acid/Dextranomer for the Treatment of Stress Urinary Incontinence

Phase 3
Not yet recruiting
Conditions
Urinary Stress Incontinence (SI)
Interventions
Procedure: Intraurethral injection
Procedure: Mid-urethral sling
Registration Number
NCT06606613
Lead Sponsor

Brief Summary

The investigators aimed to evaluate the effectiveness and safety of intraurethral cross-linked hyaluronic acid/dextranomer (CLHA/Dx) injection for the treatment of stress urinary incontinence (SUI) in women.

Detailed Description

This single-center prospective pre-post interventional study was conducted between October 2025 and April 2025 with 60 women . Quality of life was evaluated with the Incontinence Quality of Life Scale (I-QoL) and the lower urinary tract symptoms of women were evaluated with the International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms Modules (ICIQ-FLUTS). Incontinence status was assessed via the Stamey Incontinence Grade scale. The need for additional treatment (re-injection, other surgical approaches, etc.) was recorded.

Participants were followed up to 6 months after intervention. All outcomes of interest and complications were evaluated/recorded at three preplanned visits (postoperative 1st, 3rd, 6th, months).

Change in the Stamey Incontinence Grade at 6monthsChange from baseline at 6months.

All patients were evaluated as follows: Grade 0: No incontinence; Grade 1: Incontinence with coughing or straining; Grade 2: Incontinence with change in position or walking; Grade 3: Total incontinence at all times.Stamey grading is specifically a 4-level scale of incontinence severity, ranging from 0 (continent/dry) to 3 (total incontinence, regardless of activity)

Change in the Incontinence Questionnaire Female Lower Urinary Tract Symptoms Modules (ICIQ-FLUTS) scores at 3Change from baseline at 3 month

All patients were evaluated with the ICIQ-FLUTS which is a questionnaire for evaluating female lower urinary tract symptoms and impact on quality of life of the patients.The ICIQ-FLUTS consists of 12 questions related to LUTS divided into three areas: filling (4 questions), voiding (3 questions), and incontinence (5 questions). The answers are based on experiences with LUTS in the previous four weeks. The score is calculated by domain and it ranges from zero to ten in each question. As the score increases, the severity of the symptom increases.

Change in the Incontinence Quality of Life Scale (I-QOL) scores at 3 monthsChange from baseline at 3 month

All patients were evaluated İth. the I-QOL which has 22 questions with the following 3 subscales: avoid and limiting behaviors (items), psychosocial impacts (9 items), and social embarassment (5 items).The I-QOL is divided into 3 subscales:Avoidance and limiting behavior (ALB),Psychosocial impact (PSI),Social embarrassment (SE). Subjects use a 5-point response scale with values ranging from 1 (extremely) to 5 (not at all). A mean score for each subscale is calculated (averaging the scores for the items in each subscale) as well as a total score for all 22 items (sum of all subscale scores).The scores are then transformed to a 'Scale score' ranging from 0-100 points for ease of interpretation: Scale score = (sum of the items - lowest possible score)/possible raw score range X 100.
