A non-inflatable penile implant, also known as a malleable or semi-rigid implant, is a surgical treatment option for individuals experiencing erectile dysfunction (ED). It provides a permanent solution for those who have not found success with other ED therapies, helping them achieve and maintain an erection suitable for sexual activity.
Understanding Non-Inflatable Penile Implants
A non-inflatable penile implant consists of two flexible, silicone rods surgically placed within the penis. These rods provide a constant state of rigidity, allowing for sexual intercourse at any time. Unlike inflatable implants, this device is mechanically simpler, as it involves no pumps or reservoirs.
The semi-rigid rods are inserted into the corpus cavernosum, the internal structure of the penis. This placement supports the penis and keeps it firm. The rods can be manually positioned for sexual activity or bent downwards for concealment, offering control over their appearance.
Who Is a Suitable Candidate?
Individuals considered for a non-inflatable penile implant typically have erectile dysfunction that has not responded to other forms of treatment. These alternative therapies may include oral medications, penile injections, or vacuum constriction devices. The implant is often a last-line therapy when less invasive options have proven ineffective.
Specific medical conditions may lead to considering this implant. These include advanced diabetes mellitus, ED following a prostatectomy, or Peyronie’s disease, which can cause penile deformity and impact erectile function. The decision to proceed is a shared one between the patient and a urologist.
Candidates are often men aged 50 to 90, especially those who have undergone treatments for prostate, bladder, or colon cancer. The permanent nature of this solution means it generally precludes the possibility of achieving natural erections, even if the implant were removed.
The Surgical Procedure and Recovery
The surgical placement of a non-inflatable penile implant typically takes one to two hours. The procedure is usually performed under general anesthesia, ensuring the patient is unconscious and feels no pain during the operation. A small incision is commonly made in the scrotum or above the pubic bone to insert the implant components.
Post-operative care involves managing pain and soreness at the surgical site. Patients may experience swelling and bruising, which usually improves within the first week. Some individuals may have a catheter inserted to drain urine for a day or so after surgery.
Recovery timelines vary, but light activity can typically be resumed within a few days. Strenuous activity, including heavy lifting, should be avoided for two to four weeks. Sexual activity is generally recommended to be postponed for four to six weeks to allow for proper healing.
Daily Life and Long-Term Considerations
Living with a non-inflatable implant means the penis maintains a constant state of semi-rigidity. This allows for immediate readiness for sexual activity without mechanical activation. The device can be manually positioned against the abdomen for concealment when not in use.
While the implant provides the firmness necessary for intercourse, it does not alter penile sensation, the ability to ejaculate, or achieve orgasm. The glans, or head of the penis, does not become engorged as it would with a natural erection, which can sometimes lead to a perception of reduced length.
The longevity of non-inflatable penile implants is considerable, with many devices lasting 10 to 15 years, and some even more than 20 years. Patient satisfaction rates are generally high, with studies reporting satisfaction levels between 92% and 100% for patients and 91% to 95% for their partners.
Potential Complications and What to Expect
While non-inflatable penile implant surgery is generally safe, potential complications exist. Infection is a concern, with rates typically ranging from 1% to 3% in initial procedures. Should an infection occur, the implant may need to be removed to treat it.
Other potential issues include pain at the surgical site, which is often part of the healing process, or the rare occurrence of the implant eroding through the skin. Mechanical failure of the device, though less common with non-inflatable types due to their simpler design, can also occur over time.
Less common but serious concerns include damage to the urethra during surgery, requiring repair, or the development of excessive scar tissue. Consult a medical professional regarding post-operative concerns, such as heavy bleeding, fever above 100 degrees Fahrenheit (38 degrees Celsius), or increased pain.
