Most women heal from a hysterectomy without any infection. Antibiotics given at the start of the operation and other standard surgical routines keep the odds low, at roughly 2 to 3 in 100 overall. Still, an infection can develop during recovery, often after you are already home, so knowing what normal healing feels like matters as much as knowing the risk. The type of surgery shapes the odds most: open abdominal operations carry more risk than keyhole or vaginal ones.
How Common Infection Is After a Hysterectomy
Across more than 16,000 hysterectomies in one regional group of hospitals, about 2 in 100 women developed an infection at the surgery site.1PubMed. Surgical site infection following hysterectomy: adjusted rankings in a regional collaborative About half of those, roughly 1 in 100 women overall, were deeper infections inside the pelvis rather than at the skin.2PubMed. Surgical site infection following hysterectomy: adjusted rankings in a regional collaborative A larger US national count found about 3 in 100 women diagnosed with an infection after hysterectomy for non-cancer conditions.3PubMed.

Surgery type changes the odds. Infection was about twice as common after open abdominal surgery as after keyhole surgery, about 4 in 100 versus 2 in 100.4PubMed. Predictors of surgical site infection in women undergoing hysterectomy for benign gynecologic disease: a multicenter analysis using the national surgical quality improvement program data In another set of abdominal-route operations, about 6.5 in 100 open cases became infected, compared with about 2 in 100 robotic cases and almost none of the keyhole cases.5PubMed. Abdominal Hysterectomy: Reduced Risk of Surgical Site Infection Associated with Robotic and Laparoscopic Technique When a keyhole operation had to be switched to open partway through, though, about 13 in 100 developed infection.6PubMed. Abdominal Hysterectomy: Reduced Risk of Surgical Site Infection Associated with Robotic and Laparoscopic Technique
It helps to ask which route your operation is planned to use: vaginal, keyhole, robotic, or open abdominal. Some conditions, such as a very large uterus or cancer, may require open surgery. Ask how likely a switch to open surgery is in your case.
Urinary infections are a separate risk of similar size. Bladder infections affect about 2 in 100 women after hysterectomy.7PubMed. Length of Catheter Use After Hysterectomy as a Risk Factor for Urinary Tract Infection The urine catheter used during and after surgery gives bacteria a way in, and the risk climbs the longer it stays.
Warning Signs of Infection Versus Normal Healing
A low fever in the first 24 to 48 hours after surgery is common and is the body reacting to the operation.8Thomson Medical. Signs of Infection After a Hysterectomy: What to Watch For A temperature above 38°C (100.4°F) after that is a reason to contact your doctor.9Thomson Medical. Signs of Infection After a Hysterectomy: What to Watch For
Pain should ease a little each day, so pain that grows days or weeks after surgery, or stops responding to medicine that worked, is a warning sign.10Thomson Medical. Signs of Infection After a Hysterectomy: What to Watch For Some vaginal discharge is normal for the first few weeks.11Thomson Medical. Signs of Infection After a Hysterectomy: What to Watch For Discharge that turns yellow, green or grey, smells strongly, or gets heavier is not normal.12Thomson Medical. Signs of Infection After a Hysterectomy: What to Watch For
Healing redness stays a thin rim along the cut and fades.13Acibadem Hospitals Group. Robotic Hysterectomy Warning Signs: Redness, Discharge, Fever Infection redness spreads outward, feels hot, and hurts more each day, most often within the first two weeks.14Acibadem Hospitals Group. Robotic Hysterectomy Warning Signs: Redness, Discharge, Fever Swelling, warmth, or pus or fluid leaking from the incision are signs of wound infection.15Thomson Medical. Signs of Infection After a Hysterectomy: What to Watch For
The more useful question is whether today is worse than yesterday and keeps getting worse over several days instead of settling after rest. Pain that is new in character, such as sharp, throbbing, or one-sided where it was a dull ache before, is worth mentioning even if the level is modest. Chills, sweats, or loss of appetite alongside any of these changes strengthen the case for a call.
A simple daily check at home makes the trend easier to see. If you feel warm or unwell, take your temperature at the same times each day. Look at the incision in good light, or have someone photograph it so you can compare day to day. Note the color and smell of discharge on your pad, and rate your pain, noting whether your medicine still controls it. When you call, have these ready: your surgery date and type, your highest temperature and when you had it, what changed and when it started, and any pain medicine or antibiotics you are taking. Infections usually appear after you go home, before your scheduled check, and calling early often means simpler treatment.
Rarely, an infection triggers sepsis, a dangerous body-wide reaction to infection. Red flags include fever, a racing heart, low blood pressure, rising belly pain, foul discharge, and confusion.16Penningtons Manches Cooper. Sepsis after gynaecological surgery – clinical and medicolegal considerations Fast breathing and feeling faint are also warning signs of sepsis.17PubMed Central. Surgical site infections and sepsis in gynecological surgery These signs mean going to an emergency department rather than waiting for a callback.
Where Infections Happen and What Each Feels Like
The vaginal cuff is the stitched top of the vagina where the uterus was removed. Infection here usually starts after discharge home, with moderate but growing lower belly pain and yellow, pus-like discharge.18PubMed Central. Pelvic Surgical Site Infections in Gynecologic Surgery On exam, the cuff is red, swollen, and much more tender than expected.19PubMed Central. Pelvic Surgical Site Infections in Gynecologic Surgery
Sometimes infection collects into a pocket of pus or infected blood in the pelvis. These often clear with combined antibiotics, though larger pockets may need draining.20Obstetrics and Gynecology Clinics of North America. Infections After Gynecologic Surgery
Incision infections apply mainly to abdominal, keyhole or robotic cuts on the belly. Bladder infections bring burning, urgency or frequent urination, and are linked to how long a catheter stayed in.21PubMed. Length of Catheter Use After Hysterectomy as a Risk Factor for Urinary Tract Infection
Rarely the cuff can come apart, and an infection there is strongly linked to this happening.22PubMed. Risk factors for vaginal cuff dehiscence after total laparoscopic hysterectomy: A retrospective study A pocket of blood at the cuff is also tied to both infection and reopening.23Italian Journal of Gynaecology and Obstetrics. Predictive risk factors of vaginal cuff infection and vaginal cuff dehiscence in Egyptian female patients undergoing total laparoscopic hysterectomy for benign gynecological conditions Sudden fluid gush, pressure, or something bulging from the vagina needs urgent care.
Symptoms often overlap, so a doctor’s exam sorts them out. That exam usually includes a pelvic check of the cuff, an ultrasound or CT scan if a pus pocket is suspected, and urine and blood tests for bladder infection or wider spread.
The vagina normally carries bacteria, and the operation opens a path between that bacteria-filled space and the sterile tissues of the pelvis. That is why the cuff and deeper pelvic tissues are common infection sites even when a skin incision heals perfectly. Small collections of blood at the cuff can give bacteria a place to grow, which is why bleeding and infection are linked.
How Infection After a Hysterectomy Is Treated
Surgery-site infections are treated with antibiotics that cover the range of bacteria found in the pelvis.24Global Library of Women’s Medicine. Diagnosis and Management of Postoperative Infection Deeper pelvic infections are often treated in hospital with a combination of antibiotics given through a vein.25Global Library of Women’s Medicine. Diagnosis and Management of Postoperative Infection
Incision infections may need the wound opened and cleaned so pus can drain. Surgical drainage is rarely needed for pelvic infections except in certain locations.26Obstetrics and Gynecology Clinics of North America. Infections After Gynecologic Surgery
In practice, mild bladder or skin infections often mean a course of pills at home. Deeper infections may mean a hospital stay with drip antibiotics, and you usually switch to pills once the fever settles. Finish the full course even when you feel better.
Pelvic infections usually involve several kinds of bacteria at once, including some that live without oxygen, so doctors start with antibiotics that cover many types. The first choice is often made before test results return, because waiting would let the infection progress. If cultures from a wound, urine, or blood identify the bacteria, the doctor may narrow or change the antibiotic to fit.
Fever and pain usually improve within a couple of days of the right antibiotic. If they don’t, call back. Delay sex and heavy lifting until your doctor clears you.
Who Has a Higher Risk of Infection
Having a BMI of 30 or more raises infection odds by roughly half to three-quarters.27PubMed. Risk factors for surgical site infection in patients after hysterectomy: a systematic review and meta-analysis Diabetes raises the odds by roughly half.28PubMed. Risk factors for surgical site infection in patients after hysterectomy: a systematic review and meta-analysis Smoking raises them by about 40%,29PubMed Central. Risk factors for surgical site infection (SSI) in patients undergoing hysterectomy: a systematic review and meta-analysis and needing a blood transfusion more than doubles them.30PubMed Central. Risk factors for surgical site infection (SSI) in patients undergoing hysterectomy: a systematic review and meta-analysis
Surgery matters too. In abdominal hysterectomies, open surgery carried nearly three times the odds of keyhole surgery.31PubMed. Risk factors for surgical site infection after abdominal hysterectomy, New York State, 2015-2018 Operations lasting more than about three hours, and cancer surgery, also raised the odds.32PubMed. Risk factors for surgical site infection after abdominal hysterectomy, New York State, 2015-2018 Age over 75 was linked to more infection in one large group of abdominal-route cases.33PubMed. Abdominal Hysterectomy: Reduced Risk of Surgical Site Infection Associated with Robotic and Laparoscopic Technique
For bladder infection, going home with a catheter more than tripled the odds, and about 6.5 in 100 such women got one.34PubMed. Length of Catheter Use After Hysterectomy as a Risk Factor for Urinary Tract Infection After cancer surgery needing a catheter longer than a week, smoking and long catheter use were the main risks.35PubMed. Risk factors for catheter-associated urinary tract infections following radical hysterectomy for cervical cancer So ask when the catheter will come out and whether you will go home with it. If you do, keep the bag below your bladder and wash your hands before handling it.
What Helps Prevent Infection
A dose of antibiotics before hysterectomy sharply cuts infection, from about 16 in 100 women without it to 1 to 6 in 100.36PubMed Central. Antibiotic prophylaxis for elective hysterectomy It works for both vaginal and abdominal hysterectomies.37PubMed Central. Antibiotic prophylaxis for elective hysterectomy The standard choice, usually cefazolin, a cephalosporin related to penicillin, had the lowest infection rate, under 2 in 100.38PubMed Central. Prophylactic Antibiotic Choice and Risk of Surgical Site Infection After Hysterectomy If you have a penicillin allergy, ask whether it can be checked, because alternatives carried higher infection rates.39PubMed Central. Prophylactic Antibiotic Choice and Risk of Surgical Site Infection After Hysterectomy
Many people who think they are allergic to penicillin are not, since childhood rashes or stomach upset after the drug are often not true allergy. Telling your team exactly what reaction you had helps them judge whether the standard antibiotic is safe for you. Raise this at your pre-surgery appointment, not on the morning of the operation, so there is time to check. If you truly cannot take it, your team will choose an alternative, and it is reasonable to ask how they will keep your infection risk low.
The vagina is washed with an antiseptic before surgery, usually iodine-based or chlorhexidine. In one large comparison, iodine cleansing was linked to fewer infections and bladder infections than chlorhexidine.40PubMed. Vaginal preparation with povidone-iodine or chlorhexidine before hysterectomy: a propensity score matched analysis Other testing found stronger chlorhexidine left fewer bacteria, and either may be used.41PubMed Central. Assessment of Pre-operative Vaginal Preparation for Laparoscopic Hysterectomy An imbalance of vaginal bacteria, known as bacterial vaginosis, triples the risk of cuff infection after abdominal hysterectomy.42PubMed Central. Bacterial Vaginosis and Post-Operative Pelvic Infections Mention unusual discharge or a fishy odor before surgery so it can be checked and treated.
In the weeks before surgery, ask about support for quitting smoking. If you have diabetes, work with your doctor on keeping blood sugar controlled.
Afterward, keep the incision clean and dry, follow your wound-care instructions, and wash your hands before touching it. Shower as instructed rather than soaking in a bath early. Avoid tampons, douching and sex until you are cleared, since the stitched top of the vagina is still healing. Drink fluids and empty your bladder regularly.
How Long the Infection Risk Lasts
In the first 1 to 2 days, low fever and soreness are common. Days 3 to 14 are the main window for infection signs. From weeks 2 to 6, discharge should lighten and pain should fade. Increasing pain several weeks out still deserves a call.43Thomson Medical. Signs of Infection After a Hysterectomy: What to Watch For44Acibadem Hospitals Group. Robotic Hysterectomy Warning Signs: Redness, Discharge, Fever45PubMed Central. Pelvic Surgical Site Infections in Gynecologic Surgery After your doctor clears you, new symptoms are less likely to be a surgical infection but are still worth checking.
