Erectile dysfunction (ED) can be fatal to men. Aging, irregular life, work stress, psychological stress, trauma, disease, medication and surgery can all contribute to ED. Fortunately, the present is a wonderful time and ED is no longer an insurmountable problem. The majority of clinical ED (more than 90%) can be improved by medication, the drug is the familiar little blue tablet – sildenafil (Viagra), the majority of men suffering from ED as long as they have it, they can show their virility. In fact, sildenafil is only one of the representatives, similar drugs also include tadalafil, vardenafil and so on. They all belong to the phosphodiesterase 5 (PDE5) inhibitors, can effectively improve the erectile function of the penis, as long as the doctor under the guidance of taking, the incidence of adverse reactions is very low, very safe. What about the remaining 10% of refractory ED? First we need to understand its etiology. First, vascular sclerosis disease, the most common is diabetes, hyperglycemia will cause hardening and occlusion of the cavernous arteries of the penis, resulting in ED; second, nerve damage, with the increased incidence of prostate cancer, more and more young patients undergo radical tumor surgery, there is a high probability that the surgery will damage the nerves controlling penile erection, resulting in permanent ED; third, trauma, trauma involving the pelvis such as car accidents, work-related injuries, etc. can also lead to permanent ED due to the impact on the blood supply to the penile corpus cavernosum or damage to the erectile nerve. Since modern medicine has not been able to etiologically reverse the hardening of the corpus cavernosum arteries and repair the damage to the erectile nerve, we can only find another way to save the country. Currently, the ultimate weapon in the treatment of ED is the penile prosthesis. Let’s first get to know its structure, penile prosthesis has many types and specifications, the most commonly used is the expansion prosthesis, which overcomes the inherent defects of previous generations of products, has a long service life, easy to operate and other advantages. 1, reservoir sac: capacity of about 100ml, this part will be placed behind the pubic bone during surgery. 2.Expansion body: During the surgery, these two cylindrical expansion bodies will be placed in the penile corpus cavernosum (one on the left and one on the right) 3.Pump: By squeezing the pump, the water in the water storage sac will flow to the expansion body. 4.Release valve: After squeezing the release valve, water will flow from the expansion body back into the bladder, which is a component with the pump and will be placed in the scrotum during the surgery. 5.Connecting catheter: connects the water reservoir, the expansion body and the pump to each other and ensures a good seal. It does look a little abstract, right? Don’t rush, put it in now. Operation method: Under normal circumstances, the water is located in the water storage bladder, no water in the expansion body, the penis is in a non-erect state. By squeezing the pump, liquid flows from the water bladder to the expansion body, and the penis gradually becomes erect until it reaches a satisfactory level of erection. By continuously pressing the release valve without letting go, the fluid will return from the expansion body to the reservoir sac and the penis returns to a non-erect state. A few questions of concern: What groups of people are suitable for this procedure? Those with loss of erectile function due to cavernous vasculopathy and for whom medication has failed; those with ED due to erectile nerve damage from radical prostatectomy; those with ED due to cavernous and/or erectile nerve damage from trauma. Is there any difference between an erection brought about by a prosthesis and a natural erection? An erection controlled by a prosthesis is similar to a natural erection in that the erection is often harder than a natural erection, but the prosthesis does not increase the length of the penis after erection, while the glans does not engorge or harden due to the expansion of the prosthesis. The prosthesis does not change the sensation on the skin of the penis or the man’s ability to achieve orgasm, nor does it affect ejaculation. However, once a penile prosthesis is placed, it may disrupt the natural erectile reflex. Men usually cannot get an erection without inflating the implant. Even if the prosthesis is removed, the natural erection cannot be restored. Will I be embarrassed if I take a shower or hot tub in a public bathroom? The surgical scar of the implant is hidden underneath the penis (where the base of the penis meets the scrotum); it is small enough to be undetectable to the untrained eye, so you will not be embarrassed in locker rooms or public baths. Are there risks and adverse effects? There are risks and adverse reactions associated with any surgery, but the incidence of risks and adverse reactions for this procedure is low. Common ones include surgical bleeding, which in severe cases requires reoperation to stop the bleeding (<1% incidence); prosthesis infection (<1% incidence), which requires removal of the prosthesis if necessary (<1% incidence); prosthesis erosion of normal tissue; and prosthesis malfunction (<1% incidence). What is the lifespan of the prosthesis? According to previous statistics, the failure rate of penile prostheses is very low, the vast majority of them last for a long time and rarely need to be replaced due to mechanical failure. Patient satisfaction after implantation of the prosthesis is high, up to 80 to 90 % or more.
