Bandl's ring
Pronunciation: BAND-ulz ring
A pathological retraction ring of the uterus that forms at the junction between the upper and lower uterine segments during obstructed labor.
Full Definition
Bandl's ring, also known as a pathological retraction ring, is a dangerous complication of prolonged obstructed labor characterized by excessive retraction of the upper uterine segment, creating a visible or palpable ridge across the abdomen. This condition occurs when the lower uterine segment becomes overstretched while the upper segment contracts forcefully against an obstruction, such as cephalopelvic disproportion or malpresentation. The ring typically forms at the junction between the upper and lower uterine segments and rises progressively higher on the abdomen as labor continues. Bandl's ring is a sign of impending uterine rupture and requires immediate cesarean delivery.
Usage
Usage note: Always include the possessive apostrophe; this is an eponymous term named after Ludwig Bandl.
