In the population of patients with prostate cancer, survivorship has come to the forefront of continuity-of-care. Penile prosthesis surgery remains an excellent option for restoring erectile function to those for whom more conservative measures have failed.
Penile erection is the culmination of complex series of highly integrated phenomena involving the central nervous system, peripheral nervous system, endocrine system and the vascular system. These systems must be working in concert and at a high level in order for full erection to occur.
ED may occur when there is an impairment or derangement to any of these systems. ED has been defined as the inability of a man to achieve or maintain an erection sufficient for satisfactory penetrative sexual intercourse 1. Post-RP ED may be neurogenic, venogenic, arteriogenic or a combination of these etiologies. In all cases, injury of the cavernous nerves occurs during dissection of the prostate. The injury, whether caused by contact, traction, electro-cautery or transection, initiates a cascade of events that culminates in ED.
Microscopically, cavernous nerve-fiber injury initiates Wallerian degeneration that will incapacitate the axon back to the cell body, typically at the level of the spinal cord. The lack of nervous input at the end-organ cavernous muscle is a major contributor to cavernosal tissue degeneration and atrophy 2 , 3.
Venous leakage is another underlying mechanism responsible for ED after prostatectomy. Bilateral cavernosal nerve injury has been shown to induce cavernosal smooth muscle death which will lead to veno-occlusive dysfunction 3.
The initiating factor in the development of arteriogenic ED as a result of radical pelvic surgery is transection of the accessory pudendal arteries. These arteries arise from the peri-prostatic vasculature and course toward the penis and providing a significant portion of the arterial inflow required for normal erectile function 8 , 9.
This wide range of values can largely be attributed to failure to control various confounding factors including age, degree of nerve sparing, different definition of potency and preoperative ED. However, they are not uniformly effective. In a subset of patients who initially respond, the response deteriorates over time as progressive cavernosal tissue damage occurs and subsequent venous leak develops 18 , 21 , Penile implant surgery is a viable treatment option in patients in whom nonsurgical ED treatments are unsatisfactory or are associated with adverse effects The utilization rate of penile implants after RP varies from 0.
The higher rate of 1. There are numerous reasons that could be postulated for low utilization of penile implants. Firstly, prostate cancer treatment modalities have improved, thereby decreasing the incidence of ED that is unresponsive to nonsurgical intervention. Secondly, effective nonsurgical treatment modalities have been developed as alternatives to surgical treatment, predominantly PDE5Is. Meta-analysis of contemporary publications by Tal et al. Nevertheless, Stanley et al.
Technique of dilation of fibrotic corpora. Corporal crossover and urethral perforation are more likely to occur during dilation of fibrotic corpora After placing the stretched penis into anatomical position urethral meatus pointing in a superior direction , a small dilating instrument is placed into the corporotomy and slowly advanced in a latero-superior direction until it reaches the mid-glans penis.
Sequential dilation is needed until the cavernosa accepts a Fr. The most important caveat to remember is to orient the dilating instrument in a latero-superior direction when advancing the dilator within the corporal space This will prevent corporal crossover, as well as, provide a visual representation of the location of the dilator within the corpora. Tools used for dilation may include Metzenbaum scissors, Hagar dilators, Brooks dilators, Rossello cavernotomes, Mooreville cavernotomes, and the dialmezinsert dilator Technique of corporal measurement.
After corporotomy, PDS stay sutures of are placed at the corporotomy edge. The sutures are used for traction, as well as, for closure of the corporotomy after insertion of the prosthesis. Historically, corporal dilation would then ensue with Brooks or Hegar dilators. After ensuring the corporal space was dilated to 14 mm, the corporal length was then measured and the prosthesis placed.
In the contemporary setting, many implanters first measure the length of the corpora with the Furlow This narrow device provides enough passive dilation to place an inflatable prosthesis, especially if the corpora are non-fibrotic. If the corpora are fibrotic, the implanter would then dilate the corpora to ensure smooth insertion of the prosthesis When dilating or measuring the corpora, it is imperative to direct any instrumentation laterally to avoid urethral injury or corporal crossover To measure the length of the corpora, gently advance the cylindrical measuring device proximally within the corporal space.
When the bottom of the corpora cavernosa is reached, a measurement is recorded. The measuring instrument is passed distally towards the glans penis while angling the instrument laterally. A distal measurement is recorded and added to the proximal measurement.
There should be no more than a 1-cm discrepancy between the right and left corpora. Both proximal and distal corporal crossover can happen during dilation, measurement, or cylinder placement In addition, the initial correct distal tunneling technique using laterally directed dilators will help avoid crossover Side-by-side placement of the Brooks or Hagar dilators in each corpus to check for symmetry and proper positioning is the best way to check for proximal or distal crossover If a crossover is detected, the dilator may simply be redirected with the contralateral dilator left in place to prevent repeat crossover Proximal crural perforation is suspected when there is asymmetry of proximally positioned dilators or a significant length differential.
Gentle dilation and corporal measurement can prevent this manageable complication. Distal corporal and urethral perforation requires termination of the procedure, especially if distal perforation occurs during dilation of the first side If a second side is perforated after successful cylinder placement of the contralateral side, the single cylinder may be left on the non-perforated side Urethral tear may be repaired or, if very small, left to heal over the catheter Many surgeons will abandon the case during urethral injury in fear of prosthesis infection.
The reservoir is normally placed in space of Retzius. This is done to reduce the creation of inguinal floor weakness and to reduce the potential risk of visceral injury. After ensuring complete bladder drainage, the index finger is placed through the IPP incision and advanced to the medial aspect of the external inguinal ring.
Using firm pressure, the finger is advanced in a posterior direction, piercing transversalis fascia. If finger pressure is inadequate, the fascia can be perforated with the tip of an instrument scissors or clamp. This action will create a rent large enough to insinuate an index finger into the space of Retzius. Alternatively, a long-bladed nasal speculum is useful in expanding the retroperitoneal space. If the space of Retzius is obliterated due to previous pelvic surgery, ectopic placement of the reservoir should be considered 40 , The reservoir may be placed in the deep to the abdominal musculature superior or posterior to transversalis fascia A Foerster or Debakey clamp may be used to advance the deflated reservoir to its ectopic position.
Stember et al reported the outcomes of men who underwent ectopic reservoir placement The remainder had reservoirs placed in the anterior transversalis space. No injuries to the bowel or major blood vessels occurred with initial insertion of the reservoir, however two patients experienced bladder injury. Eight patients required reservoir revision secondary to herniation The most serious intraoperative complications of penile prosthesis insertion occur during reservoir placement Traditionally, the reservoir is placed blindly in a retrograde fashion into the space of Retzius through a penoscrotal incision.
The serious potential complications include vascular injury, bowel perforation and bladder perforation Vascular injury arterial or venous avulsion may occur during overly aggressive finger or instrument dilation of the inguinal ring. In the event of brisk bleeding, tapenade with an index finger or sponge stick is advised Direct access into the space of Retzius is then accomplished through an inguinal incision. Meticulous inspection of the pelvic sidewall will frequently localize the avulsed venous vessel.
In the event of vascular injury of the major pelvic vessels, consultation from a vascular surgeon is recommended. Bladder injury is a complication that should be recognized and managed immediately.
Prior pelvic surgery or radiation may result in adherence or fixation to the pelvic sidewall. Bladder perforation can happen while piercing the transversalis fascia Emptying the bladder prior to placing the reservoir can decrease the incidence of these injuries. Bladder injury is noted when gross blood is seen in the urine or the observation of urine emanating through the IPP incision The injury can be confirmed via flexible cystoscopy or by an on-table cystogram.
In case of bladder injury due to scissors, the reservoir should be removed and placed on the contralateral side. The bladder should be drained for 7—10 days. Cystogram should be done prior to catheter removal. The bowel may be damaged in a similar mechanism to bladder injury during reservoir placement Upon recognition bowel injury succus entericus in the wound , a general surgeon should be consulted for repair and the prosthesis removed. Serial reports regarding of penile prosthesis surgery outcomes demonstrate excellent long-term mechanical reliability of contemporary prosthesis models; satisfaction is superior when compared to PDE5Is and injections.
Carson et al. Steege et al. In a study by Rajpurkar et al. The psychosexual adaptation to penile implant may take up to 6 months.
The patients experience a marked enhancement in erectile function with elevation of libido. Apprehension regarding the maintenance of an erection during intercourse is markedly assuaged. In addition to an upsurge in the regularity of sexual activity, a decrease in feeling of sadness, depression, anxiety and an improvement in sexual satisfaction has also been noted Two major factors contributing to high level of satisfaction are rapid generation of erection and consistently excellent rigidity.
For patients to have a realistic expectation of how their implant will function and how big their penis will be after implantation, Dr. This will be your new big prosthetic penis. When the implant is inflated or moved into position, it has a similar feel to a man's regular erection, both in girth and stiffness. Eid meets with every patient to carefully prepare them for penile implant surgery by explaining the results and ensuring appropriate expectations. We use only the best and most expensive materials, so we had the best quality products.
Penis prosthesis. Penile Implant / Prosthesis
Penile prosthesis - Wikipedia
A penile prosthesis , or penile implant, is a medical device which is surgically implanted within the corpora cavernosa of the penis during a surgical procedure. The device is indicated for use in men with organic or treatment-resistant impotence or erectile dysfunction that is the result of various physical conditions such as cardiovascular disease, diabetes, pelvic trauma, Peyronie's disease , or as the result of prostate cancer treatments. A penile implant is one treatment option available to individuals who are unable to achieve or maintain an erection adequate for successful sexual intercourse or penetration.
Its primary use is for men with erectile dysfunction from vascular conditions cardiovascular disease, high blood pressure, diabetes , congenital anomalies , iatrogenic , accidental penile or pelvic trauma, Peyronie's disease, or as a result of prostate cancer treatments.
This implant is normally considered when less invasive medical treatments such as oral medications PDE5 inhibitors: Viagra, Levitra, Cialis , penile injections, or vacuum erection devices are unsuccessful, provide an unsatisfactory result, or are contraindicated. Sometimes a penile prosthesis is implanted during surgery to alter, construct or reconstruct the penis in phalloplasty.
The British Journal of Urology International reports  that unlike metoidioplasty for female to male sexual reassignment patients, which may result in a penis that is long but narrow, current total phalloplasty neophallus creation using a musculocutaneous latissimus dorsi flap could result in a long, large volume penis which enables safe insertion of any type of penile prosthesis.
This same technique enables male victims of minor to serious iatrogenic, accidental or intentional penile trauma injuries or even total emasculation caused by accidents, child abuse or self-mutilation to have penises suitable for penile prosthesis implantation enabling successful sexual intercourse.
In some cases of genital reconstructive surgery , implantation of a semirigid prosthesis is recommended for three months after total phalloplasty to prevent phallic retraction. It can be replaced later with an inflatable one. There are two primary types of penile prosthesis: noninflatable semirigid devices, and inflatable devices. With this type of implant the penis is always semi-rigid and therefore may be difficult to conceal.
Hydraulic, inflatable prosthesis also exist and were first described in by Brantley Scott et al. The device is inflated by squeezing the pump several times to transfer fluid from the reservoir to the chambers in the penis. After intercourse, a valve next to the pump is manually operated, allowing fluid to be released from the penis not instantaneously; squeezing the penis may be necessary , causing the penis to return to a flaccid or semi-flaccid condition. Almost all implanted penile prosthesis devices perform satisfactorily for a decade or more before needing replacement.
