Inflating the Penile Prosthesis

Most patients will begin cycling (INFLATING/DEFLATING) the penile implant between the 4th and 6th post-operative week. Only begin inflating the implant if you are 100% sure that you will be able to deflate it. To ascertain that you will be able to deflate the penile implant, make sure that the deflation footprint of the pump is manually recognizable and readily palpable. Soaking in a hot bath may facilitate this. If swelling is present and you are not sure that you can feel and distinguish all of the different components of the pump you should wait another two weeks before attempting inflation.

It is normal to experience pain in the shaft of the penis and for it to be sore during the first two weeks of inflation. For this reason we recommend that you take two Tylenol with codeine, wait 30 minutes and get into a very hot bath tub for 15 minutes before you begin to squeeze the pump. 



Instructions for Inflating Your Penile Implant

Inflating penile implant instructions
In order to switch the pump into the inflating mode, you need to initially give vigorous and rapid squeeze to the bulb. You should feel a gentle tug and all subsequently inflations should not require as much force as the initial one. 
Inflating penile implant instructions
Anywhere from 10 to 60 squeezes may be required to fully inflate the cylinders. The larger the cylinder the more fluid will be needed to achieve firmness, the more times the pump will need to be squeezed. You cannot damage the pump or over inflate the cylinders, so squeeze it several times until it becomes as hard as a marble.

At this point rock the shaft of the penis from side to side and up and down and squeeze the pump again a few times until the shaft of the penis becomes very firm. You should be able to squeeze it three to six more times. All cylinder folds and ridges should completely disappear and the shaft of the penis should be rock hard when the implant is fully inflated.   

  • The majority of patients are unable to inflate the device fully during the first month of use. 
  • Once inflated keep the erection up for 15 minutes or more and then deflate it completely. 
  • Perform this maneuver everyday for the first 2 to 4 weeks after learning how to use the pump or until the penis is no longer sore when fully inflated.

Inflation and Deflation of Penile Prosthesis

Dr. Eid shows a patient inflating and deflating his penile implant.



It is very important to fully deflate the cylinders for two important reasons:

  1. The first is to maintain the reservoir at full capacity and prevent formation of scar tissue over a partially filled reservoir. If this occurs the cylinders will no longer be able to be fully deflated and a partial permanent erection will always be present. This will also lead to the complaint of "auto-inflation" of the device as you become more proficient at deflation later on.

  2. The second is to prevent atrophy of the overlying flesh and glans of the penis that surround the prosthesis cylinders. If atrophy occurs, the scar tissue capsule that surrounds the cylinders will become lose overtime and the shaft of the penis will feel less rigid when the cylinders are inflated. The glans will shrink and the tip of the cylinders will be more noticeable. In order to fully deflate the cylinders please squeeze the shaft of the penis with one hand while the other activates the deflation footprint of the pump. Repeat these maneuvers three times or until you are satisfied that the cylinders are flat and loose inside the shaft of the penis.

We recommend that you inflate your implant every day for the first month until the pump becomes more compliant and you become very comfortable with its function. If you encounter any difficulties please do not hesitate to contact Dr. Eid.
