(also known as transperineal) ultrasound was originally used in France in the 1980s and proved to be more fruitful than the transabdominal approach.
Previously, various methods have been used to assess PVR, which include the use of transabdominal, transvaginal, or translabial
ultrasound or catheterization.

The pubovisceral muscle (PVM) anatomy of 30 female cadavers was analyzed via 3D translabial
ultrasonography to confirm LMA.
The use of transabdominal ultrasound in the evaluation of lower urinary tract and pelvic floor dysfunction was first documented in the early 1980's with translabial
, transrectal, and transvaginal technique developed somewhat later.
Patients were then referred for a carefully directed translabial
ultrasound scan of the rectum and anal sphincters.
Furthermore, the translabial
or transperineal technique is not always successful because of reduced visualization secondary to bowel gas (39).
or transvaginal scanning can be helpful in evaluating a patient with suspected placenta previa.
Though no prospective, randomized trial has compared transvaginal with translabial
sonography in the imaging of placenta previa, TVS is safe and well tolerated, with no increase in bleeding.

Transperineal or translabial
sonography can be used where vaginal access is difficult.
