Abstract:
The insertion of two different types of intrauterine devices (Multiload 250 and Silver T) has been monitored in 97 patients through systematic exploration by echography and hysteroscopy. Both techniques seem to be highly reliable in spite of the observation of 9% misplacements of the IUDs not detected by echography. In addition, hysteroscopy enables the diagnosis of frequent associated pathology (endometrial hyperplasia, endometriosis, polyps) difficult to diagnose by echography. The present study demonstrates the fact that the ultrasonography confirmation of IUD localization in the uterus was not always accurate.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
