How to Prevent Infection After Urology Surgery
You can reduce infection risk after urology surgery by keeping wounds and catheter/drain systems clean, washing hands before care, following antibiotic instructions exactly, avoiding unnecessary catheter disconnections and reporting fever or drainage problems early. More antibiotics are not automatically better: prolonged or leftover antibiotics can cause side effects and resistance without preventing every infection. If you have a catheter, DJ stent or nephrostomy, maintaining unobstructed urine drainage is especially important because infection plus obstruction can become serious quickly.
Start before surgery
Infection prevention begins before the operation. Tell your team about:
- Fever or urinary symptoms.
- Recent urine cultures.
- Diabetes control.
- Skin infection near the operative site.
- Previous resistant bacteria.
- Antibiotic allergies.
If your surgeon requests a urine culture, complete it in time for review.
Showering and skin preparation
NICE advises patients to shower or bathe with soap the day before or the day of surgery. Do not shave the surgical area with a razor unless instructed; razors can cause microscopic skin cuts. If hair removal is needed, clinical teams usually use clippers.
Antibiotics: use the right amount, not the maximum amount
Some urological operations require prophylactic antibiotics and some do not. The choice depends on the procedure, urine culture and local resistance patterns.
After discharge:
- Take antibiotics exactly as prescribed.
- Do not extend the course yourself.
- Do not use leftover antibiotics for a new fever.
- Report allergy symptoms or severe diarrhoea.
Wound care
Wash hands before touching the wound or dressing. Keep the dressing as instructed. When showering is allowed, clean gently and pat dry.
Avoid applying unprescribed powders, oils, antiseptics or antibiotic creams to a closed incision.
Catheter infection prevention
With a urinary catheter:
- Keep the bag below bladder level.
- Avoid kinks and pulling.
- Wash hands before and after handling it.
- Keep genital skin clean with routine washing.
- Avoid unnecessary disconnection of the drainage system.
- Empty the bag using the outlet without contaminating the tip.
Foul-smelling or cloudy urine alone does not prove infection; fever and systemic symptoms matter.
DJ stent infection prevention
A stent is internal and cannot be “cleaned” at home. Maintain normal hygiene and hydration appropriate to your medical condition. Fever, chills or worsening flank pain with a stent needs prompt review.
Nephrostomy care
A nephrostomy has an external skin entry site. Keep the dressing secure, prevent tube traction and maintain drainage. If it stops draining, falls out or leaks significantly with fever/pain, seek urgent medical advice.
Diabetes and infection risk
High blood glucose can impair host defence and is associated with postoperative infection. Follow your diabetes plan and monitor glucose as instructed. Do not make major insulin changes without guidance.
Smoking and recovery
Smoking impairs wound healing and increases respiratory complications. Stopping before surgery and remaining smoke-free during recovery can help.
What actually lowers infection risk—and what does not
| Helpful | Not a substitute for medical care |
|---|---|
| Keeping wounds and tube sites clean according to the discharge plan | Repeatedly applying strong antiseptics to irritate healing skin |
| Keeping catheter drainage closed and unobstructed | Disconnecting the bag repeatedly to “clean” the system |
| Using antibiotics only for the prescribed indication and duration | Continuing leftover antibiotics “just in case” |
| Managing diabetes, hydration and urinary drainage appropriately | Relying on cranberry, supplements or home remedies to treat postoperative infection |
| Reporting fever, chills or poor drainage early | Masking fever and waiting several days when symptoms are worsening |
Warning signs of infection
Contact your doctor for:
- Fever or rigors.
- Increasing wound redness, warmth or swelling.
- Pus/cloudy wound discharge.
- Wound opening.
- Worsening urinary burning with systemic symptoms.
- New flank pain with fever.
- Catheter/nephrostomy blockage with illness.
Severe weakness, confusion, rapid breathing or collapse may indicate sepsis and requires emergency care.
What not to do
- Do not repeatedly open a closed drainage system.
- Do not shave or scratch a healing wound.
- Do not self-start antibiotics for every urinary symptom.
- Do not ignore a blocked drainage tube.
- Do not soak an unhealed wound in a bath/pool unless cleared.
FAQs
Should I take antibiotics until my catheter is removed?
Not routinely for every patient. Antibiotic need depends on the operation, infection risk and urine findings.
Does cranberry prevent postoperative UTI?
It should not be relied upon to prevent a surgical or catheter-associated infection.
Is cloudy urine normal with a catheter?
It can occur for several reasons. Fever, chills, pain or feeling unwell makes infection more concerning.
Can I use antiseptic liquid daily around the catheter?
Routine gentle hygiene is usually sufficient. Strong antiseptics can irritate skin unless specifically recommended.
