This project aims to investigate whether transpubic ultrasound can be used to reliably assess voiding in females when performed by suitably trained sonographers.

We are seeking 30 women who have never delivered a baby to participate.

Volunteers are required to attend a brief (15 minutes) orientation session with the sonographer prior to their participation. This will provide the volunteer with information regarding their participation in the study including the need to pass urine whilst being scanned; a potentially embarrassing situation.

Following the orientation session, three scanning sessions lasting approximately 40 minutes each will required.

Consenting volunteers should arrive with a full bladder and are scanned in a seated position whilst urinating. The ultrasound transducer is then placed on the skin of the pelvic area and an ultrasound recording of the soft tissue activity during urination is performed. Volunteers are asked to initiate urination, stop once half way through and then completely empty the bladder.
