A penile implant is a highly successful operation, and much of that success comes from careful preparation before surgery. Before recommending a penile implant, a uroandrologist runs a set of routine investigations to confirm you are a suitable candidate, to make the surgery as safe as possible, and — crucially — to reduce the risk of infection. Here is what that assessment usually includes.
History and examination
The evaluation starts with a detailed medical and sexual history — the nature and duration of your erectile dysfunction, previous treatments, other health conditions, and medications. A focused physical examination assesses the penis, any curvature or scarring (Peyronie’s disease), and your general fitness for surgery.

Routine blood tests
- Blood sugar and HbA1c: Good diabetes control is very important — poorly controlled sugar raises the risk of implant infection, so it is optimised before surgery.
- Complete blood count and basic kidney and liver function
- Coagulation profile to check clotting, especially if you take blood thinners
- Hormone tests (such as testosterone) where relevant
Urine test and infection screening
Because an implant is a permanent device, preventing infection is a top priority. A urine test and culture is done to make sure there is no urinary infection before surgery; any infection is treated first. Any active infection anywhere in the body is addressed before proceeding.
Fitness for anaesthesia and other checks
- ECG and cardiac/anaesthetic assessment to confirm you are fit for anaesthesia, particularly if you have heart disease or diabetes
- Penile Doppler ultrasound in selected cases, to assess blood flow and tissue
- Review of medications — blood thinners and some other drugs may need adjusting before surgery

Just as important is counselling: your Uroandrologist will explain the procedure, expectations, and recovery so you and (where appropriate) your partner can make an informed decision.
Frequently Asked Questions
Why is diabetes control so important?
High blood sugar increases the risk of implant infection and slows healing. Optimising your sugar before surgery meaningfully improves safety and outcomes.
Why check the urine before penile surgery?
An unnoticed urinary infection could spread to the implant. Testing and treating any infection first is a key step in keeping the device safe.
How long does the work-up take?
Most investigations can be completed within a few days to a couple of weeks, after which a surgery date is planned.
