|Official Title:||3-D Endoanal Ultrasound: Normative Anatomy of the Anal Sphincter in Nulliparous Females|
- To establish normative data for the anal sphincter complex in asymptomatic nulliparous females without sphincter disruption sphincter. [ Time Frame: 15 minute exam ]
|Study Start Date:||December 2007|
|Study Completion Date:||June 2012|
|Primary Completion Date:||June 2012 (Final data collection date for primary outcome measure)|
nulliparous women over the age of 18
Procedure: 3-D Endoanal Ultrasound
The subject will be placed in the supine position with their feet in the stirrups and a drape will be used, exposing only the anus and perineum in order to introduce the probe. In order to prevent and minimize any potential discomfort, the lubricated ultrasound probe will be gently inserted into the anal canal up to the anal verge, with minimal manipulation of the probe once inserted. The scan lasts approximately two minutes and the entire exam will take no more than five minutes.
Participants will be asked to complete a one page questionnaire. This questionnaire will address whether perineal trauma, sphincter lacerations, anal incontinence, and fecal urgency impact the subject on any level. Subjects will also be asked about their bowel habits and history of problems with bowel movements. Subjects will then be asked to undergo an ultrasound study of the anal sphincter at the time of enrollment. Completing the entire study will take no more than 15 minutes. This will be done at the doctor's office. Answering the questionnaire will take no more than 5 minutes.
The endoanal ultrasound is a probe with a diameter equivalent to the index finger. It is inserted in the rectum and measures the length and width of the sphincter muscles.
