Is Another Treatment Option Better For Preservation Of Erectile Function

What is Nerve Grafting/Regeneration Surgery? Will this help men after prostatectomy get erections?

The growing interest in pelvic radiation, including brachytherapy, as an alternative to surgery can be attributed in part to the supposition that surgery carries a higher risk of erectile dysfunction. Clearly, surgery is associated with an immediate, precipitous loss of erectile function that does not occur when radiation therapy is performed, although with surgery recovery is possible in many with appropriately extended follow-up. Radiation therapy, by contrast, often results in a steady decline in erectile function to a hardly trivial degree over time.

Devices For Identifying The Cavernous Nerves During Radical Prostatectomy

Owing to the lack of visibility of the cavernous nerves during RARP, erectile dysfunction after surgery has remained the most crucial postoperative complication in the robotic surgery era., Thus, many novel methods for mapping the cavernous nerves during radical prostatectomy have been developed so far. Being able to recognize the cavernous nerves during radical prostatectomy might help in their preservation, leading to improved postoperative genitourinary function. In this section, the diagnostic technologies of intraoperative diagnosis of cavernous nerves during radical prostatectomy are reported. The summary of the advantages and disadvantages of these devices for identifying the cavernous nerves during radical prostatectomy is presented in .

What To Do If My Symptoms Are Not Improved After The Greenlight Pvp Laser Of Prostate

While the urine stream is the first symptom to improve after the Greenlight laser of the prostate, other symptoms may take a few months to improve. In particular, urinary urgency, burning with urination, and frequent urination can take a few months to improve.

Usually, symptoms improve slowly over time. If the symptoms are severe, medical treatment with medications for overactive bladder such as Vesicare, Myrbetriq, oxybutynin, and Detrol is sometimes necessary.

If symptoms do not improve sufficiently as expected within the first 3 months after surgery, cystoscopy, uroflow and bladder ultrasound, as well as urodynamic testing, may be necessary to determine the cause of lack of improvement.

Infrequently, patients may develop urethral stricture or bladder neck contracture. In these situations, the urine stream may become worse a few weeks to a few months after the procedure. If this occurs, re-evaluation is necessary.

Nerve Regeneration After Radical Prostatectomy

Nerve Regeneration: Erectile Nerve Regeneration

Filed in Life After Treatment

Nerve regeneration after radical prostatectomy usually does take some time, assuming that both nerve bundles around the prostate were able to be preserved by the surgeon. This is because the nerves and arteries that control erections need time to recover and heal. This article explains why this is the case, and what can be done to speed up the healing process.

Can Nerve Grafts Restore Erectile Function

Until 1981, urologists believed that the nerves responsible for erections ran through the prostate. But that year, Dutch urologist Pieter Donker showed that the nerves ran down the sides of the gland, not through it. That discovery got urologic surgeons thinking: perhaps a cancerous prostate could be removed without harming the nerves, preserving a mans erectile function.

The following year, the first so-called nerve-sparing radical prostatectomy was performed. Today, most surgeons aim to spare the neurovascular bundles when performing prostate surgery. This helps men who were potent prior to surgery regain erectile function, and some studies show that it may also minimize urinary incontinence.

Unfortunately, the surgeon, whose main goal is to eliminate the cancer, cant always spare the nerves. For example, the cancer might have grown through the prostate capsule and into the nerves, making their removal a must. Or the cancer might be at the edges of the gland, increasing the risk that a few cancerous cells might be left behind the surgeon might make a wider cut to ensure a cure but sacrifice erectile nerves in the process. In some cases, neither nerve bundle can be saved.

Are There New Strategies In The Near Future That May Be Helpful In Improving Erection Recovery After Surgery

Recent strategies have included cavernous nerve interposition grafting and neuromodulatory therapy. The former, as a surgical innovation meant to reestablish continuity of the nerve tissue to the penis may be particularly applicable when nerve tissue has been excised during prostate removal. In the modern era of commonly early diagnosed prostate cancer, nerve-sparing technique remains indicated for the majority of surgically treated patients.

Neuromodulatory therapy, represents an exciting, rapidly developing approach to revitalize intact nerves and promote nerve growth. Therapeutic prospects include neurotrophins, neuroimmunophilin ligands, neuronal cell death inhibitors, nerve guides, tissue engineering/stem cell therapy, electrical stimulation, and even gene therapy.

> > > One Crazy Prostate Trick All Men Over 40 Should Try

Symptomatic treatment of an enlarged prostate usually involves a combination of medication and lifestyle changes. A diet rich in fruits and vegetables may be the best option if you suffer from chronic urination. It will help the body adjust to the increased size of the prostate. Also, taking regular urination intervals will help retrain the bladder to function properly. Inactivity also contributes to urine retention, and cold temperatures can increase the urge to urinate.

Invasive treatment of enlarged prostate includes medication that relieves the pressure on the urethra and bladder. However, if the condition is severe, it may require surgical intervention. If treatment is not successful, the enlarged prostate can become a potentially life-threatening disease. As the hormone levels in the body change, the enlarged prostate can lead to various complications, including urinary retention and even cancer. This is why it is critical to see a doctor for further evaluation.

A physician can recommend a number of treatments to address an enlarged prostate. An enlarged prostate will require surgery to relieve the symptoms. In most cases, surgical treatment for an enlargement of the penis is enough. Moreover, a doctor may recommend a course of treatment based on symptoms. A TURP procedure is not painful and requires less recovery time than open surgery. The recovery period will be shorter and less traumatic.

Bilateral Nerve Pain Following Prostatectomy

Nerve regeneration after radical prostatectomy

I was diagnosed with prostate cancer 4 years ago. Biopsy advised one agressive cancer and 2 not as agressive. Had a prostatectomy. Woke up from surgery with severe burning pain in and around my rear. This continued in my 3/4 days in hospital. Worst hospital stay ever. As soon as I left hospital for home, I had difficulty sitting due to the burning pain in my buttocks and down the back of my thighs.My cancer was advanced prostate cancer due to it being outside the prostate. Following radiotherapy, my PSA levels have been stable for 12 months at .04. The nerve pain down my thighs have not diminished and has radiated down under my feet. When I sit I have burning pain down the back of my thighs and burning pain under my feet when I walk. I am currently on 450mg of Lyrica a day but does not appear to be helping. As the nerve pain is bilateral my doctor believes my sciatic nerve was damaged in surgery in my lower back.Urologist advised that it has never happened before. Just lucky I guess. I was wondering if any man out there has had a similar problem following prostate surgery and what treatment has worked/not worked for them as I am desperate to get this fixed.

This result may be coincidental rather than causative, but I thought youd like to have it as one of the ideas to discuss with your doctor. Keep us posted so we can learn from your experience and, hopefully, find other questions you can put to your medical team.Martin

Why Is Radical Prostatectomy Done

Radical prostatectomy is a treatment for prostate cancer that prevents cancer from spreading outside the prostate gland. It may cure prostate cancer by removing it completely.

For patients diagnosed with prostate cancer, additional tests may be needed to determine the how far the cancer has spread. These tests help your provider decide if you are a candidate for radical prostatectomy:

Recent Findings About Regaining Potency After Radical Prostatectomy

It is important to remember that regaining erectile function takes time after radical robotic prostatectomy. Most studies in the literature use endpoints of 18-36 months after prostate cancer surgery. Nerve tissue can be easily damaged during robotic prostatectomy, regardless of the skill of the surgeon, and takes a long time to regenerate. It is believed that early postoperative medical therapy can aid an earlier return to potency.

Dr. Ahlering, a physician with UC Irvine Medical in Orange County, CA. has pioneered the use of electrocautery-free preservation of the neurovascular bundles which are essential for the return of potency after prostate surgery. A recent study by Dr. Patrick Walsh and associates at John Hopkins has shown that mono and bipolar cautery near the potency nerves severely impact the erectile function of dogs. Mono and bipolar cautery are routinely used by many institutions to limit the bleeding during surgery by heat-sealing or ‘cauterizing’ the bleeding vessels.

The nerves for potency are intertwined with a bundle of blood vessels, which must be controlled during prostate cancer surgery to prevent large blood losses. Thus to preserve the nerves of potency, a surgeon also must prevent the bleeding of these vessels also. Cautery is considered a standard method of sealing the blood vessels, allowing the nerve bundles to now be properly visualized.

For comparison we show the standard data on open prostatectomy potency :

How Is The Surgery Done

How long does fatigue last after prostate surgery?

Like other surgeries for prostate cancer, nerve-sparing surgeries can be done a few different ways:

In a standard âopenâ surgery, your surgeon makes a cut in your abdomen from just below your navel to your pubic bone. Then they cut away your prostate and tumor. They carefully avoid nearby nerves.

In a laparoscopic surgery, surgeons make much smaller incisions, each less than half an inch. Then, they use laparoscopic tools and cameras to do the operation. The tools are inserted into your abdomen through narrow tubes.

In robotic-assisted nerve-sparing prostate cancer surgery, your surgeon makes a small cut in your abdomen and places robotic tools in the hole. They control the tools from a computer to do the operation.

Chronic Cavernosal Tissue Changes

In the chronic phase of injury, the persistent loss of nerve signal conduction results in loss of spontaneous nocturnal erections and relative cavernosal ischemia. The pathophysiologic consequence is cavernosal smooth muscle apoptosis, upregulation of TGF-beta and collagen deposition within the corpora . Cavernous neurotomy studies in rats have demonstrated that corporal smooth muscle apoptosis begins 1 day after injury and peaks within the first week . This fibrotic reaction impairs full expansion of the venous sinuses within the tunica and failure to adequately compress the emissary veins against the tunica. The result is veno-occlusive dysfunction in which the venous outflow occurs with the same velocity as arterial inflow. In this setting, tumescence is unable to be achieved or maintained. Furthermore, there is anatomical loss of penile length and girth as a result of the cavernosal smooth muscle fibrosis.

Vitamins To Promote Nerve Regeneration After Surgery

Surgery can lead to tissue damage due to incisions, tissue movement or other manipulation that can occur during a procedure. Any incision can potentially damage your nerves, causing numbness or other nerve defects after surgery. However, in some cases, your nerves can regenerate as part of the healing process — and specific vitamins might play a role in this regeneration.

Perineural Invasion: What Is The Significance If Perineural Invasion Is Present And Identified In A Post Op Pathology Report

There are small nerve fibers that pass through the inside of the prostate gland. These nerves secrete a growth factor that attracts prostate cancer cells. Accordingly, in the great majority of prostate cancers, the cancer cells are seen to be lined up surrounding nerve fibers. This is called perineural invasion. Perineural invasion is so common as to almost be a diagnostic feature of prostate cancer. Its clinical significance is that when it is found in a needle biopsy specimen, there is a greater chance that the tumor will be found to have spread outside the prostate gland. If the tumor has spread outside the prostate, there is a higher chance for tumor recurrence. However, if the tumor has not spread outside the prostate gland, there is little or no prognostic significance to perineural invasion.

Experimental Drug Regenerates Erectile Nerves Damaged By Prostate Surgery

A topical drug restores the function of erectile nerves damaged by radical prostatectomy, according to a study in rats.

May 20, 2021 By Albert Einstein College of Medicine

    Researchers at Albert Einstein College of Medicine have developed a topical drug that regenerates and restores the function of erectile nerves damaged by radical prostatectomy, the most common treatment for localized prostate cancer. The drug was tested in rats, and the findings were published online today in JCI Insight.

    Erectile dysfunction after radical prostatectomy has a major impact on the lives of many patients and their partners, said study co-leader David J. Sharp, Ph.D., professor of physiology & biophysics and of ophthalmology and visual sciences and professor in the Dominick P. Purpura Department of Neuroscience at Einstein. Since rats are reliable animal models in urologic research, our drug offers real hope of normal sexual function for the tens of thousands of men who undergo this surgery each year.

    Dr. Sharp, Dr. Davies, and their teams realized that injured nerves might be especially amenable to this gene-silencing drug: For unknown reasons, the FL2 gene becomes over-active after injury to nerve cells, causing the cells to produce copious amounts of FL2 enzyme.

    Treatment Of Rising Psa

    If PSA levels are rising slowly or by a small amount, a person may not need treatment. A doctor usually considers an individuals overall health, medical history, and age when giving advice on treatment.

    Doctors often use active surveillance if PSA levels are rising. Active surveillance is a series of regular tests and health checks, with treatment only if necessary. Prostate cancer often progresses very slowly, so it may be many years before a person needs treatment.

    If a person has had a prostatectomy, a doctor may also recommend radiation therapy, which kills cancer cells using high-energy particles.

    Radiation therapy is not suitable for everyone who has had a prostatectomy. If a person had radiation therapy before surgery, they cannot usually have this treatment again. Having radiation therapy a second time can cause side effects.

    Doctors may also use hormone therapy to shrink a persons tumors. This can make other treatments such as radiation therapy more effective.

    It is not always possible to prevent PSA levels from rising. The best way to safeguard health after having a prostatectomy is by undergoing regular medical checks.
