Penile Implant Surgery

Mr Darren Katz – Expert Penile Implant Surgery

Mr Darren Katz is an expert in penile prosthesis surgery and is a "high volume" implanter. He is the only Victorian Urologist to have undertaken a specialised fellowship in the USA in urological prosthetics which is accredited by the by Sexual Medicine Society of North America.

Urological prosthetics include penile implants, artificial slings, sphincters and testicular prostheses.

Mr Katz performs most of his penile implants by the MINT technique - "Minimally Invasive No Touch". He has presented on this new technique which he helped develop at multiple conferences around the world.

"Minimally Invasive" means that all components of the implant can be inserted via a 3-4cm incision hidden in the pubic hair region. As the cut is so small, patients can be discharged the next day and post surgery recovery is enhanced.

"No Touch" means the implant does not touch the skin – which is a potential cause of infection. This MINT technique has a close to zero infection rate.

Mr Katz has produced a new video on this technique which has been published in a peer-reveiwed video journal and he also presented the video at the World Meeting of Sexual Medicine in 2016. You can watch this video here.

This video was made to teach other urologists how to perform penile implant surgery and therefore involves footage of real surgery which some people may find graphic.

What is a penile implant?

Penile implants are devices known as prostheses that can restore erection in many men with erection dysfunction (ED). Penile implants require a surgical procedure and it is the most common surgery performed for treating ED.

The penis contains two erection chambers called the corpora cavernosa, which run the length of the organ. A spongy tissue fills the chambers. The corpora cavernosa are surrounded by a membrane, called the tunica albuginea. The spongy tissue contains smooth muscles, fibrous tissues, spaces, veins, and arteries. The urethra, which is the channel for urine and ejaculate, runs along the underside of the corpora cavernosa and is surrounded by the corpus spongiosum.

Types of implants

There are two main types of implants :

Malleable implants : Malleable implants usually consist of paired rods which are inserted surgically into the corpora cavernosa. The user manually adjusts the position of the penis and, therefore, the rods. Adjustment does not affect the width or length of the penis. These implants are best suited for patients who may have limited hand dexterity.


Inflatable implants : Inflatable implants consist of paired cylinders, which are surgically inserted inside the penis and can be expanded using pressurized fluid. Tubes connect the cylinders to a fluid reservoir and a pump, which are also surgically implanted. The patient inflates the cylinders by pressing on the small pump, located under the skin in the scrotum. As opposed to malleable implants, inflatable implants can expand the length and width of the penis. They also leave the penis in a more natural state when not inflated.
