A Study on the Safety and Effectiveness of Subcutaneous Silicone Penile Implant Surgery

Completed

Conditions studied: Penile Implant

In brief

This study will identify a patient population who wishes to address a variety of concerns about the size, shape, or appearance of their penis with the placement of a subcutaneous Silicone Block Penile Implant. Because the Silicone Block is placed subcutaneously, the device can provide immediate and permanent improvements to the appearance of a man's penis. The most notable improvements are enhanced penile cosmesis, improved penile girth, and improved exposure of the penile shaft outside the plane of the body. The plan is to conduct a study to examine the outcomes of this procedure with respect to: * Incidences of adverse events * Changes in flaccid penile length (through physical measurements pre and post-operatively in a consistent manner) * Changes in flaccid penile girth (through physical measurements pre and post-operatively in a consistent manner) * Changes in satisfaction scores with respect to penile size and patient self-confidence/self-esteem (through validated questionnaires)

Who can join

Age: 18 and older, up to 65. Sex: male. Healthy volunteers: accepted.

You may qualify if…

• Inclusion criteria include men who are over 18 and under 65, circumcised, who have the perception of inadequate penile girth or appearance of length of penis, or penile deviation from straight plane in flaccid condition for whatever reason. Etiologies may include:
• A retractile penis or "buried penis" from infrapubic pannus
• A loss of length following radical prostatectomy or other trauma
• Congenital or acquired (e.g., Peyronie's Disease) mild curvature of the penis with indentation deformity and with curvature less than 30 degrees with no plan to have other corrective procedures (e.g. surgery, intralesional injection of collagenase clostridium histolyticum)
• Patient perception of a penis of inadequate size and patient desire for cosmetic enhancement

You may not qualify if…

• Men who are unable to give informed consent
• An uncircumcised penis
• Micro-penis (stretched flaccid penile length <6cm)
• Prior penile girth enhancement procedure of any sort, including grafts or subcutaneous injections, previous Xiaflex injection
• History of immunosuppression and/or HIV

• Uncontrolled diabetes
• Active genitourinary skin infection
• History of recurrent or active urinary tract infection (UTI)
• Patients unwilling to comply with post-operative instructions
