Preparing for Penile Implant Surgery: What Happens Before the Operation?

Penile implant surgery is a procedure considered for men with erectile dysfunction who have not benefited from other treatment steps, and it involves placing a permanent device inside the erectile tissue of the penis (the corpora cavernosa). Contrary to what many patients assume, the factors that shape the outcome of this surgery are not limited to the few hours spent in the operating room. The preparation period beforehand is treated as a distinct part of the process, both for planning the operation technically and for ensuring that healing proceeds without complications.

The main reason preparation is handled in such detail is that a penile implant is a foreign body placed permanently inside the body. As in all surgeries involving implanted devices, the most important theme here is minimising infection risk, because an infection developing in the tissue surrounding the implant usually cannot be resolved with antibiotics alone and may require removal of the device. Preoperative assessment aims to identify and, as far as possible, correct the factors that increase this risk.

This article covers what is assessed before penile implant surgery, which tests are requested, why topics such as blood sugar and smoking come so much to the fore, and what the patient is expected to prepare for before the day of surgery.

Why does penile implant surgery require a separate preparation period?

Penile implant surgery is an elective procedure, meaning it is performed at a time considered suitable by both patient and surgeon rather than under emergency conditions. This provides an important advantage: there is time to correct the factors that increase risk before the operation. Postponing surgery in a patient with poorly controlled blood sugar, an active urinary tract infection or broken skin integrity is not a way of worsening the outcome but of protecting it.

The second aim of preparation is to shape the surgical plan around the individual. Penile anatomy, previous operations, the degree of tissue scarring (fibrosis) and the patient's expectations all determine which implant type and which surgical approach will be appropriate. This assessment takes place in the consultations beforehand, not on the operating table.

The third aim is for the patient to enter the process fully informed. A patient who knows in advance what will happen after surgery, how healing will progress and how the device will be used experiences less anxiety during recovery and adapts more easily to the recommendations given.

Which tests are requested before surgery?

The tests requested before a penile implant fall into two groups: those belonging to general surgical preparation and those specific to implant surgery. General preparation covers the anaesthetic assessment and basic laboratory work performed before any operation.

• Complete blood count and biochemistry: General indicators such as anaemia and kidney and liver function are assessed.
• Blood sugar and HbA1c: Particularly in patients with diabetes, the HbA1c value showing the average blood sugar over the past three months is treated as a separate topic.
• Coagulation tests: Bleeding tendency and the effect of any blood thinners in use are reviewed.
• Urinalysis and urine culture: Detecting a urinary tract infection that causes no symptoms is critically important before implant surgery.
• Anaesthesia consultation: Suitability for surgery is assessed in terms of cardiac, pulmonary and other systemic conditions; further tests may be requested if needed.

In addition, investigations assessing the condition of the penile tissue may be performed depending on the patient's history. In cases with a history of priapism (prolonged, painful erection), previous penile surgery or suspected advanced tissue scarring, further imaging may be considered to refine the surgical plan.

Why does blood sugar control matter so much?

Diabetes is one of the most common causes of erectile dysfunction, so a significant proportion of patients receiving a penile implant have diabetes. However, having diabetes is not in itself a barrier to surgery; what really matters is how stable the blood sugar is.

High and fluctuating blood sugar reduces the healing capacity of tissues, weakens the immune response to infection and delays wound healing. For this reason, bringing the HbA1c value into a reasonable range is aimed for before surgery. The numerical target varies from patient to patient and is set together with the patient's endocrinology or internal medicine physician; the goal here is less about hitting a threshold than about achieving a stable pattern.

Postponing surgery by a few weeks in a patient whose blood sugar is not under control may feel like an obstacle that prolongs the process. In fact, this wait serves both to reduce infection risk and to make healing more predictable. How penile implants are evaluated in patients with diabetes is a topic that warrants separate, more detailed discussion.

How does smoking affect the surgical outcome?

Smoking is a distinct topic in surgical preparation because of both its long-term effect on vascular health and its short-term effect on tissue healing. Nicotine and carbon monoxide reduce blood flow in small vessels and impair tissue oxygenation, which can slow wound healing and lower resistance to infection.

For this reason, patients scheduled for a penile implant are advised to stop smoking a certain period before surgery. Even in patients who find it difficult to quit entirely, pausing during the period before and after surgery is considered meaningful. This advice is given not to judge the patient but to support the healing process; smoking cessation clinics are also an option for those who would like help.

How are current medications adjusted before surgery?

Reviewing the medications a patient takes regularly is a standard part of preparation. The group given the most attention here is medication that increases bleeding risk.

• Blood thinners and antiplatelet medication: If these are taken for cardiac or vascular disease, the decision on whether to pause them is made together with the relevant physician; in some patients stopping the medication is not appropriate and the surgical plan is shaped accordingly.
• Painkillers and anti-rheumatic drugs: Some can increase bleeding tendency and may need adjusting before surgery.
• Herbal products and supplements: These are assessed for bleeding risk and anaesthetic interaction; patients are expected to report every product they use, including over-the-counter ones.
• Diabetes and blood pressure medication: Whether these should be taken on the morning of surgery is specified separately during the anaesthetic assessment.

None of these adjustments should be made by the patient alone. Stopping blood thinners without medical advice can carry serious risks, particularly in patients taking them for a heart valve, a vascular stent or a rhythm disorder.

Why are hidden infection sources investigated?

In implant surgery, even an infection located far from the surgical site matters, because bacteria spreading through the bloodstream can settle on the surface of a newly placed implant. For this reason, the presence of any active infection in the body is investigated before surgery.

• Urinary tract infection: If growth is detected on urine culture, even without symptoms, it is treated before surgery and clearance is confirmed with a follow-up culture.
• Dental and gum infections: A dental assessment may be requested, particularly in patients with long-neglected dental problems.
• Skin problems: Fungal infection, eczema or an open wound in the groin and genital area may require postponing surgery.
• Foot wounds: Foot examination is a topic that should not be overlooked, especially in patients with diabetes.

Clearing these sources beforehand forms part of a comprehensive approach to reducing infection risk, alongside measures applied during surgery such as the no-touch technique and the use of antibiotic-coated implants.

What happens the day and morning before surgery?

Preparations close to the operation are more practical in nature, and the patient's own adherence is decisive at this stage.

• Fasting period: Eating and drinking stop from the time specified by the anaesthetic team; this period varies with the type of anaesthesia.
• Bathing and skin cleaning: The patient is asked to shower as advised before surgery; shaving of the area is usually performed in the operating room immediately beforehand. Shaving at home days in advance is avoided because bacteria can grow in the micro-cuts created in the skin.
• Jewellery, prostheses and personal items: Rings, watches and dentures are asked to be removed.
• Companion and transport plan: Not being alone on discharge makes the first days more comfortable.
• Work and travel plans: Leave can be arranged in advance so that heavy physical activity and long journeys can be postponed during recovery.

Details such as loose, comfortable underwear and loose trousers for after surgery may seem minor, but they directly affect comfort in the first days.

Is discussing expectations part of the preparation?

One of the factors determining patient satisfaction in penile implant surgery is having discussed expectations openly beforehand. The implant is a device that provides rigidity mechanically; it is not designed to change sexual desire, the sensation of orgasm or penile size. Clarifying this distinction in advance reduces adjustment difficulties later.

Consultations generally cover the following topics: the differences between implant types, the chosen surgical approach, the healing period, when and how the device will start to be used, potential risks and the possibility of revision in the long term. Attending these consultations together with a partner can be helpful in understanding the process jointly.

Writing down questions in advance is another frequently given piece of advice; questions forgotten during a consultation often become a source of anxiety during recovery.

How long does the preparation period last?

The length of preparation varies with the patient's general condition. In a patient with no additional illness whose tests return without problems, this process can be completed within a few weeks. Where blood sugar needs stabilising, an infection source needs treating or medication needs adjusting, the process may take longer.

This waiting period is difficult for most patients; for someone who has been seeking treatment for a long time, even a delay of a few weeks can feel excessive. In implant surgery, however, preparation is regarded as part of the process just as much as the operation itself, and the steps taken during this period contribute to a smoother recovery.

Preparing for penile implant surgery is not a formality consisting of tests alone; it is a comprehensive process carried out to reduce infection risk, shape the surgical plan around the individual and clarify expectations. Stable blood sugar, stopping smoking, a clear urine culture and correctly adjusted medication are the topics that come most to the fore. Assoc.
