The urethra plays a crucial role in maintaining urinary continence. Its complex blood supply is still not well understood. Particularly in the context of urethral pressure. Urethral pressure can be measured by bladder and urethral pressure studies (urodynamic).

This study aims to use advanced imaging techniques to analyse the blood supply of the urethra and correlate it to urethral pressure measurements.

Elucidating these relationships will improve our understanding of urethral function and malfunction, and ultimately optimise diagnosis and treatment of stress urinary incontinence. A total of 35 participants with stress urinary incontinence and 35 without stress urinary incontinence will be asked to participate in this study.

Inclusion Criteria:

• Urodynamic examination
• Written informed consent
• Understanding of the German language
• Indicated urodynamic assessment
• Endovaginal and perineal ultrasound feasible

Exclusion Criteria:

• Urinary tract infections
• Transgender Population
• Pregnancy
• History of incontinence or prolapse surgery
• Pelvic prolapse higher than second degree
• Prior pelvic radiotherapy
• Prior history of gynecologic tumor

According to the ethics application, the confidentiality measures of the study do not allow the public release of participant data. However, data can be made available upon reasonable request.
