USING A PENIS PUMP AFTER A PROSTATECTOMY:
This has been the main motivation to sell penis pumps in my clinic and in my online store.
You can use a penis pump to help promote blood supply to the penis, maintain the tissue flexibility and ability of the penis to expand and stretch, encourage nerve response.
Is recommended to be used with Viagra or Cialis which may help speed up sexual recovery after surgery, speak to your specialist or GP about medication.
As a general rule you start pumping once your catheter has been removed after the surgery. Please speak to your specialist or pelvic floor physiotherapist for their recommendations first.
Starting later maybe needed if you have had any post-op complications, have tender scarring etc.
For sexual intercourse use the pump to obtain an erection and then place a constriction or C ring over the base of the penis to maintain the erection. Works best when there is some natural and spontaneous erectile function in the penis. 
 
RESEARCHED EVIDENCE FOR USE OF PENIS PUMPS AFTER PROSTATECTOMY:
are highly effective in inducing erections regardless of the cause of erectile dysfunction (ED).
can be used in the early stages of penile rehabilitation until the nerves have healed sufficiently for drug treatments to work.
when used early can facilitate earlier sexual intercourse.
has a greater patient/spousal sexual satisfaction.
can maintain penis size and length.
can lead to an earlier return to natural erections.
have a high satisfaction score and many men continue to use them long-term.
have a low risk of side effects especially when compared to drug treatments and therefore they have a greater potential to be used by many patients.
has the potential to mimic more closely natural physiology.
has shown to be a very cost-effective way of treating ED over the long-term
 
STARTING OFF:
It is recommended you gradually build up the frequently and length of time you use the pump for. You should aim to have no discomfort, swelling or pain.
General guidelines: Use pump 5-7 times/week. Pump and create erect penis, leave erect in pump for 3-5mins, deflate vacuum pump, wait 1 minute - repeat this 3 times/session.
Initially the penis may be sensitive after use, many men do not find it comfortable to have sex immediately after using their pump. However this sensitivity may reduce over time.
STOP PUMPING IF YOU HAVE ANY FORM OF DISCOMFORT, START SLOWLY! 
YOU CAN OVER PUMP! If you start off too aggressively, pump too hard, too quickly, too often and leave it on too long you can cause your penis to become bruised, sore and develop blood blisters. Expect some of these changes in mild forms in the first few weeks but they should resolve.
Always observe the penis for changes as you pump.
 
A detailed guideline for use is included with the pump to give you confidence to use the pump and get the most out of it. 
 
HEALTH WARNING:
It is not safe (is contraindicated) to use a pump if you have a bleeding disorder or on anti-coagulant therapy.
We recommend seeking medical advice before using a penis pump if you have any of the following medical conditions:
Bleeding disorders
High blood pressure
Heart disease

Diabetes type one or two
Urinary, bladder, testicular or penile problems
 
 
The American Urology Association has stated that vacuum therapy devices are a safe and effective, non-invasive treatment for erectile dysfunction. Penile injections, urethral inserts, oral medications, and implant surgery can have harmful side effects, require frequent doctor visits, and become quite expensive. Being a medically rated vacuum penis pump; it has been proven to successfully treat impotence in over 90% of men. In addition to its effectiveness, this pump system offers unique design features and a level of durability that surpasses other pumps.
