Defecation Disorders & Fecal Incontinence

Endoanal ultrasound is the gold standard for identifying sphincter tears & defects.

Sphincter Tears & Defects

Fecal incontinence has a profound impact on a patient’s life, impairing quality of life and carrying a substantial economic burden due to health costs. Patient evaluation with a detailed clinical history and examination is important to indicate the type of injury.  

Endoanal ultrasound is the gold standard for sphincter evaluation in fecal incontinence and is a simple, well-tolerated, and cost-effective technique.

Endoanal Ultrasound

The Catalyst Ultrasound System offers practitioners the ability to accurately delineate internal and external anal sphincters as well as identify any gaps or defects.

Cine/Video File

Record and playback a clip of the entire anal canal. Click frame by frame to identify the exact location of sphincter tears and defects.

Measurement tool

Catalyst software has built-in measurement tools that measure the angle, length, and percentage of internal or external sphincter tears or defects.

Probes

Halos 2D or 3D Endoanal or Transrectal probes can be used to identify, measure, and label the exact location of any sphincter tears or defects.

Ultrasound Probes

Halo ultrasound probes are designed to identify sphincter tears and defects.
