A middle age female with previous history of LSCS, presented pain in pelvic region and was advised transvaginal ultrasound to rule out the possibility of endometriosis or adhesions.

Findings:

Transvaginal ultrasound to assess the bladder, uterus and pouch of Doughlas. The ultrasound sliding sign technique detected the presence of sliding motion between two adjacent structures. This indicated that there was no adhesions in between the bladder and the uterus.

Discussion:

The transducer tip is pointed at the uterus and a gentle push-pull movement of several centimeters is started. If no adhesions are present, the organs will move freely in the pelvis. This displacement of organs is perceived on the screen as a sliding movement and mentioned as sliding sign positive.
