Abstract

Purpose: MRI characteristics in some cases of women with stress urinary incontinence. Materials and methods Retrospective, descriptive, cross-sectional study of 43 patietns. Among them, 22 patients with SUI (disease group) and 21 patients without SUI (control group) underwent of Dynamic Pelvic Magnetic Resonance Imaging (DP-MRI) at Hanoi Medical University Hospital from August 2010 to September 2022. Results:  82 % of patients in the disease group was over 49 y.o, the birthrate was 3 ± 1,1, in which the number of patients giving birth three times was 46% and mostly in vaginal delivery (86%). The mean urethral volume of the disease group (5,6 ± 2,1) was smaller than that of the control group (7,1 ± 1,8). The posterior urethrovesical angle increased statistically significant difference in the disease group during both resting and pushing (mean value was 145⁰ ± 13⁰ and 157⁰ ± 15⁰, respectively) compared to the control group (p<0,01, 95% CI). In the group of patients, the number of patients with bladder neck prolapse (72.73%) was more than the control group (57,14%) during straining, In the straining, there is an increase the mobility of the bladder neck with an average value of 21 ± 15, Conclusion Dynamic Pelvic Magnetic Resonance Imaging (DP-MRI) is a non invasive technique with excellent soft tissu resolution, providing the complete and accurate anatomical images to dignosis of Stress Urinary Incontinence (SUI)
