Why It Is Done

For men and women, pelvic ultrasound may be done to:

• Find the cause of blood in the urine (hematuria). An ultrasound of the kidneys may also be done.
• Find the cause of urinary problems.
• Look at the size of the bladder before and after urination. This can determine whether the bladder is emptying completely during urination.
• Check for growths in the pelvis.
• Guide the placement of a needle during a biopsy or when draining the fluid from a cyst or abscess.
• Check for rectal cancer and how it is responding to treatment.

For women, pelvic ultrasound may be done to:

• Find out what is causing pelvic pain.
• Look for the cause of vaginal bleeding.
• Look for pelvic inflammatory disease (PID).
• Find an intrauterine device (IUD).
• Look at the size and shape of the uterus and the thickness of the uterine lining (endometrium).
• Look at the size and shape of the ovaries.
• Check the condition and size of the ovaries during treatment for infertility.
• Confirm a pregnancy and whether it is in the uterus. Pelvic ultrasound may be used early in pregnancy to check the age of the pregnancy or to find a tubal pregnancy (ectopic pregnancy) or multiple pregnancy.
• Check the cervical length in a pregnant woman at risk for preterm labour.
• Check a lump found during a pelvic examination.
• Check uterine fibroids found during a pelvic examination. Pelvic ultrasound may also be done to check the growth of uterine fibroids.
• Guide a procedure to remove an ovarian follicle for in vitro fertilization.

For men, pelvic ultrasound may be done to:

• Look at the seminal vesicles and the prostate gland.
• Check for prostate cancer. Other tests, including digital rectal examination, prostate-specific antigen blood test, and prostate biopsy, may also be used.
• See if urinary problems are being caused by a prostate that is getting bigger, such as from benign prostatic hypertrophy (BPH).
• Check to see if a problem with the prostate gland may be causing infertility.
