Hypertonic Saline Injection For Urinary Incontinence

Phase 3
Completed
Conditions
Urinary Stress Incontinence
Interventions
Procedure: Periurethral injection
Drug: Hypertonic (10%) saline
Registration Number
NCT04812574
Lead Sponsor
Turgut Ozal University
Brief Summary

The investigators aimed to evaluate the effectiveness and safety of periurethral hypertonic saline (10% NaCl) injection for the treatment of stress urinary incontinence (SUI) and stress-predominant mixed urinary incontinence (MUI) in women.

Detailed Description

This single-center prospective pre-post interventional study was conducted between January 2014 and April 2018 with 65 women (44 SUI, 21 MUI). 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. Patients with MUI also were evaluated using the Urinary Distress Inventory-6 (UDI-6). The need for additional treatment (re-injection, other surgical approaches, etc.) was recorded.

Participants were followed up to 24 months after intervention. All outcomes of interest and complications were evaluated/recorded at six preplanned visits (postoperative 1st, 3rd, 6th, 12th, 18th, 24th months).
