The purpose of this study was conducted to determine the influence of low level laser on pelvic floor muscles and fascia in cases of stress urinary incontinence (SUI). This Randomized controlled trial study was carried out on 30 women, their age ranged from (40-55) years old, and they were diagnosed clinically as having SUI by Urogynecologist and by MRI. They were randomly selected and divided into two equal groups (A and B). The study group (A) received low level laser for 15 minutes and pelvic floor muscles exercises program for 30 minutes two sessions per week for twelve weeks, while the control group (B) received only pelvic floor muscles exercises program for 30 minutes two sessions per week for twelve weeks. Results: Statistical analysis showed statistically improvement in pelvic floor muscles strength (p<0.001) measured by perineometer, Modified Oxford Grading scale and SUI questionnaire in favor of group (A) compared to group (B).MRI reported a significant improvement in dynamic assessment in levator plate angle, iliococcygeal angle, anorectal angle, width and height of levator hiatus in favor of group (A) compared to group (B) post treatment. So, it could be concluded that low level laser in addition to pelvic floor exercises has a great effect on improving efficacy of pelvic floor musculature and fascia, and decreasing frequency, amount and severity of urinary incontinence. So low level laser may be an effective intervention in treating stress urinary incontinence
