Hysterectomy and Pap Smears

Viewer Question: Is it necessary to have a Pap smear if you have had a hysterectomy?
Dr. Stöppler's Answer: In some types of hysterectomy, the entire uterus is removed, including the cervix
(the opening to the uterus). If you have had your cervix removed, you usually won't need to have regular Pap smears. In other types of hysterectomies, the cervix is left intact, and the portion of the uterus above the cervix is removed. In this case, the cervix is still present and
Pap smears are still required.

What is a hysterectomy?
A hysterectomy is a surgical procedure whereby the uterus (womb) is removed.
This surgery for women is the most common non-obstetrical procedure in the United States.
How common is hysterectomy?
Approximately 300 out of every 100,000 women will undergo a hysterectomy.
Why is a hysterectomy performed?
The most common reason hysterectomy is performed is for uterine fibroids. Other common reasons are:
Only 10% of hysterectomies are performed for cancer. This article will primarily focus on the use of hysterectomy for non-cancerous, non-emergency reasons, which can involve even more challenging decisions for women and their doctors.
Uterine fibroids (also known as uterine leiomyomata) are by far the most common reason a hysterectomy is performed. Uterine fibroids are benign growths of the uterus, the cause of which is unknown. Although the vast majority are benign, meaning they do not cause or turn into cancer, uterine fibroids can cause medical problems. Indications for hysterectomy in cases of uterine fibroids are excessive size (usually greater than the size of a two-month pregnancy), pressure or pain, and/or bleeding severe enough to produce anemia. Pelvic relaxation is another condition that can require treatment with a hysterectomy. In this condition, a woman experiences a loosening of the support muscles and tissues in the pelvic floor area. Mild relaxation can cause first degree prolapse, in which the cervix (the uterine opening) is about halfway down into the vagina. In second degree prolapse, the cervix or leading edge of the uterus has moved to the vaginal opening, and in third degree prolapse, the cervix and uterus protrude past the vaginal opening. Second and third degree uterine prolapse must be treated with hysterectomy. A vaginal wall weakness such as a cystocele, rectocele, or urethrocele, can lead to symptoms such as urinary incontinence (unintentional loss of urine), pelvic heaviness, and impaired sexual performance. Urine loss tends to be aggravated by sneezing, coughing, jumping, or laughing. Childbearing is the most common risk factor for pelvic relaxation, though there may be other causes. Avoidance of vaginal birth and having a caesarean section doesn't necessarily eliminate the risk of developing pelvic relaxation.
A hysterectomy is also performed to treat uterine cancer or very severe pre-cancers (called dysplasia, carcinoma in situ, or CIN III, or microinvasive carcinoma of the cervix). A hysterectomy for endometrial cancer (uterine lining cancer) has an obvious purpose, that of removal of the cancer from the body. This procedure is the foundation of treatment for cancer of the uterus.
