Risks of Hysterectomy
Hysterectomy poses some risks of major and minor
complications. However, most women do not have complications after a
hysterectomy.
Some studies have shown complication rates that are about the same
for total laparoscopic hysterectomy (TLH), laparoscopically-assisted vaginal
hysterectomy (LAVH), and total abdominal hysterectomy (TAH).10, 11 Your risk of problems after
surgery may be higher or lower than average. This may depend in part on how
experienced the surgeon is.
Major medical complications after hysterectomy
Rates of major complications after vaginal
hysterectomy and abdominal hysterectomy (rounded to nearest 0.5%):9
Complications after
hysterectomy| Type of complication | Vaginal hysterectomy (without
laparoscopy) | Abdominal hysterectomy (without
laparoscopy) |
|---|
Heavy blood loss requiring blood transfusion | 3% | 2.5% |
Bowel injury | 0 | 1% |
Bladder injury | 1% | 1% |
Blood clot in lung (pulmonary
embolism) | 0 | 1% |
Anesthesia problems (such as breathing or heart
problems) | 0 | 0 |
Need to change to abdominal incision during
surgery | 4% | 0.5% (repeat incision) |
Wound pulling open (dehiscence) | 0 | 0.5% |
Collection of blood (hematoma) at the surgery site needing
surgical drainage | 1% | 1% |
At least one major complication | 9.5% | 6% |
In the study described above, the major complication rate was
nearly twice as high after laparoscopic abdominal
hysterectomies than after open abdominal
hysterectomies. Complication rates were about the same for vaginal and
laparoscopic vaginal surgeries. (These rates do not apply to radical
hysterectomy done to treat cancer.)
- About 11% of women had at least one major
complication after the laparoscopic abdominal surgery, compared with about 6%
of those who had an open abdominal surgery.
- Although most major
complications were equally rare after both types of surgery, more women had
heavy blood loss requiring a transfusion after abdominal laparoscopic
hysterectomy (4.6%) than after open abdominal hysterectomy (2.4%).
Minor medical complications after hysterectomy
Rates of minor complications after vaginal
hysterectomy and abdominal hysterectomy (rounded to nearest 0.5%):9
Minor medical complications after
hysterectomy| Type of complication | Vaginal hysterectomy (without
laparoscopy) | Abdominal hysterectomy (without
laparoscopy) |
|---|
Heavy blood loss not requiring transfusion | 1% | 1% |
Fever | 7% | 3% |
Infection | 14% | 16% |
Collection of blood (hematoma) at the surgery site
not needing surgical drainage | 6% | 6% |
At least one minor complication | 28% | 27% |
In the study described above, there was no significant difference
in minor complication rates, whether the hysterectomy was laparoscopic,
vaginal, or abdominal. (These rates do not apply to radical hysterectomy done
to treat cancer.)
Infection risk is lowest when your doctor gives you
antibiotic medicine at the time of surgery.12
Other ongoing complications of hysterectomy include:
- Difficulty urinating. This is more common
after removal of
lymph nodes,
ovaries, and structures that support the uterus
(radical hysterectomy).
- Weakness of the pelvic muscles and
ligaments that support the vagina, bladder, and rectum. The weakness can cause
bladder or bowel problems, such as
cystocele,
rectocele, or urinary incontinence (which is most
common in women over age 60).13Kegel exercises may
help strengthen the pelvic muscles and ligaments. However, some women need
other treatments, including additional surgery.
- Continued
heavy bleeding. Some vaginal bleeding within 4 to 6
weeks following a hysterectomy is expected. However, call your health
professional if bleeding continues to be heavy.
- Early
menopause caused by a slow, yet early decline of the
ovaries (premature ovarian failure).3
- The
formation of scar tissue (adhesions) in the pelvic area.
