Catheters, Intrauterine, Ultrasonography
Definition : Intrauterine catheters designed for infusion of saline into the uterus to enhance the transvaginal ultrasonographic image. These catheters usually include a balloon (rounded or elliptic) on or near their distal tip to be placed in the cervical canal and a central lumen for injection of the saline solution during the ultrasonic image procedure (hysterosonography). They are thin enough (e.g., 5 to 7 Fr) to allow placement next to ultrasound probes. Some of these catheters may also be used to inject opaque medium for radiographic purposes. Hysterosonographic procedures are mostly used to assist the clinician in the establishment of a specific diagnosis when endometrial thickness exist (e.g., detection of polyps).
