Open Radical Prostatectomy
This is a procedure carried out in an effort to cure prostate cancer. The entire prostate gland is removed as opposed to a laser operation (HoLEP) where just the middle part of the prostate is removed in order to allow men to pass urine more freely.
It is important you have nothing to eat or drink for at least six hours prior to your operation. The anaesthetist will usually place a spinal block which helps with post-operative pain relief prior to putting you to sleep.
The procedure itself is performed through a midline lower abdominal incision extending from below the umbilicus to just above the pubic bone. The prostate and attached seminal vesicles are removed and then the bladder is brought down and joined to the urethra. The wound is closed using dissolvable stitches. You may or may not require a pelvic drain which is usually removed on the first post-operative day. A urinary catheter is left in for 10 days in order to allow the join between the bladder and the urethra to heal. The operation takes about one and a half to 2 hours and the usual hospital stay is around 2 to 3 days.
Occasionally, depending on how aggressive your cancer is, the pelvic lymph nodes may need to be removed along with the prostate.
Intraoperative complications
The main potential intraoperative complication is the risk of significant blood loss requiring a blood transfusion. The average blood loss of this procedure over the last 10 years is around 500 ml and it is very rare (<1%), to have to transfuse anyone. Having said that, if you need it you will get it!
The posterior surface of the prostate is in close proximity to the lower bowel and there is a small risk of injury to the rectum. This uncommon, occurring in less than 1% of patients. It is usually easily recognised and is repaired at the time.
You might need to be on antibiotics for a week or so in the unlikely event that this happens but there are usually no long-term problems as a result.
Post-operative complications
The three main risks following this procedure are urinary incontinence, impotence and bladder neck stenosis (narrowing at the bladder neck).
Incontinence
Normal continence is controlled by a circular muscle that surrounds the urethra called the external urethral sphincter. This muscle is closely associated with the apex of the prostate and can be damaged to a degree during removal of the gland. It is very common therefore for patients to have some urinary leakage following the procedure. This can be quite severe in the first week or two after the catheter comes out but usually rapidly improves and by 6 to 8 weeks most patients have reasonable control. By three months about 95% of patients are essentially dry. A minority of patients never regain normal continence. If you are unlucky enough to be in this 5% group you will not have to put up with this for ever as there are various, relatively minor, procedures which can resolve this problem.
Impotence
The nerves responsible for normal erections are the cavernous nerves. They run very close to the side of the prostate and are therefore at risk of damage during radical prostatectomy. Nerve sparing surgery is possible but preserving the nerves has a secondary importance compared to ensuring the cancer has been removed. Some patients will have high-risk disease, and in these, nerve sparing would not be appropriate as there is a high chance of leaving cancer behind.
Even with nerve sparing there is no guarantee of maintaining normal erections. Return of erections depends on a number of other factors besides the nerves including patient age and preoperative erection quality. A young patient with good erectile function and bilateral nerve sparing however has a good chance of regaining normal erectile function, somewhere in the order of around 80%.
It is important to note that it can take some time for erections to return. This is because the nerves don't like being handled or manipulated and develop something called neuropraxia. It can take one or two years for normal erections to fully return. During this time you will be offered active erectile rehabilitation.
It is also worth noting that the erectile nerves are different than the sensory nerves. You will still be able to have an orgasm after radical prostatectomy. There is of course no ejaculate and you will be unable to have children.
Bladder neck stenosis
This is due to excessive scarring at the join between the bladder neck and urethra. It occurs in around 5% of patients. Patients notice their urinary flow (which usually is much better following radical prostatectomy), gradually decreasing. They may find that their continence, which has been quite good, deteriorates. This condition is usually simple to treat and just involves incising the scar tissue. (Under general anaesthetic).
Further management from the cancer point of view depends a little on the riskiness of your disease. Some patients may need further procedures such as post-operative radiotherapy although we usually have an idea of who is likely to need this prior to carrying out the radical prostatectomy in the first place.
In others usually all that is needed is regular PSA monitoring. The prostate is the only organ to make PSA and if you have had a cure for prostate cancer your PSA should drop to undetectable levels (less than 0.02). It is important not to do a PSA blood test too early post operatively as sometimes it takes a while for the existing PSA in the blood to be cleared from the bloodstream.
If your PSA should start to climb following surgery then it is important that we know about this as soon as possible as salvage radiotherapy, given early, is often a potentially curative second-line option.
