Detailed Description
This study is a prospective, randomized, 3-arm parallel pilot study. Study subjects will be women currently experiencing female stress urinary incontinence (SUI) and stress-predominant mixed urinary incontinence (SMUI) with a degree of intrinsic sphincter deficiency for a minimum duration of 6 months prior to enrolment. Diagnosis of SUI with a degree of intrinsic sphincter deficiency will be performed using urodynamic and clinical assessment.
Subjects will undergo sham, intravaginal, and the combination of intravaginal and intraurethral treatment with the 2940 nm Er:yttrium aluminum garnet Er:YAG laser at two time points, 4 weeks apart. Primary objective is to assess the tolerability and safety of the intraurethral 2940nm Er:YAG laser technique in combination with intravaginal 2940nm Er:YAG laser method for the treatment of stress urinary incontinence through 6 months follow-up and extend to 12 months follow-up.
Secondary objective is to assess the effectiveness of the intravaginal and combination of intraurethral/intravaginal laser treatments using subjective and objective measures, as well as improvement in quality of life through 6 months follow-up and extend to 12 months follow-up.
