A pelvic ultrasound is a diagnostic imaging test that uses sound waves to create real-time pictures of the organs located in the pelvic area — the region between the abdomen and the legs. The images, called sonograms, allow healthcare providers to evaluate internal structures without surgery or radiation. It is a safe, commonly available, and relatively quick procedure performed in imaging centers or medical clinics.
Pelvic ultrasound helps visualize important organs such as the bladder, uterus, ovaries, fallopian tubes, vagina, prostate, and rectum. Because the images are produced in real time, the examination can also show movement and blood flow within the examined structures.
Types of pelvic ultrasound
Depending on the medical concern, different approaches may be used:
•
Abdominal ultrasound
– performed externally over the lower abdomen.
•
Transvaginal ultrasound
– performed with a small probe inserted into the vagina to examine reproductive organs more closely.
•
Rectal (transrectal) ultrasound
– performed through the rectum; in some cases used to assess the prostate.
•
Pregnancy ultrasound
– used to monitor fetal development in the uterus.
The choice of method depends on the symptoms and the organ being evaluated.
When is it recommended?
A healthcare provider may suggest a pelvic ultrasound if a person experiences:
• Pelvic or lower abdominal pain
• Pain during urination or sexual intercourse
• Difficulty becoming pregnant
• Irregular menstrual bleeding or bleeding after menopause
• Abdominal swelling
• Urinary leakage
The exam can assist in identifying various conditions affecting the bladder, reproductive organs, prostate, or surrounding structures.
Additional uses and results
Pelvic ultrasound may also guide certain procedures, such as collecting a small tissue sample (biopsy), or help confirm the placement of an intrauterine device (IUD).
Benefits
Pelvic ultrasound is widely used because it:
• Produces detailed images
• Is completed within a short time (often 15–60 minutes)
• Does not use radiation
