How Surgeons Measure and Size Penile Implants: A Comprehensive Medical Guide

Written By: Jared Mortensen

A penile implant procedure requires precise measurements and careful sizing to achieve optimal results for patients with erectile dysfunction. This comprehensive guide explores the detailed process that urologists and surgical teams use to determine the appropriate implant dimensions for each patient's unique anatomy.

Understanding Penile Implant Basics

Before diving into the measurement process, it's important to understand that penile implants consist of cylindrical components that are surgically placed within the erectile chambers of the penis (corpora cavernosa). These implants come in two main types: inflatable and malleable devices. The sizing process is crucial regardless of implant type, as proper fit directly impacts both functional outcomes and patient satisfaction. Learn more about implant types

Pre-Operative Assessment

The sizing process actually begins before surgery during the initial consultation. Surgeons perform several important preliminary measurements and assessments:

Physical Examination

During the physical exam, doctors evaluate several key factors that influence implant sizing:

 

  • Stretched penile length measurement
  • Assessment of penile anatomy and tissue quality
  • Evaluation of any existing conditions like Peyronie's disease
  • Examination of previous surgical scarring if present More about pre-operative assessment

Medical History Review

The surgical team carefully reviews relevant medical history that could affect sizing:

 

  • Previous pelvic or penile surgeries
  • History of priapism
  • Presence of fibrosis or scarring
  • Diabetes or other conditions affecting tissue quality Clinical considerations

Intraoperative Measurement Process

The most critical measurements occur during surgery while the patient is under anesthesia. This process involves several precise steps:

Corporal Measurement

Surgeons use specialized tools called Furlow inserters and corporeal dilators to obtain exact measurements:

 

  1. A small incision is made to access the corpora cavernosa
  2. The Furlow inserter is carefully placed from tip to base
  3. Measurements are taken of both left and right corpora
  4. Multiple measurements ensure accuracy Detailed measurement techniques

Width Determination

Determining the appropriate cylinder width involves:

 

  1. Sequential dilation using gradually larger sizing tools
  2. Assessment of tissue elasticity and resistance
  3. Evaluation of maximum safe diameter
  4. Consideration of patient anatomy Surgical sizing guidelines

Advanced Sizing Considerations

Modern penile implant surgery involves several sophisticated considerations:

Reservoir Placement

For inflatable implants, surgeons must also determine:

 

Length Optimization

Experienced surgeons employ various techniques to optimize length:

 

Post-Operative Care and Outcomes

After precise sizing and successful implantation, proper follow-up care is essential:

Recovery Process

Patients typically experience:

 

  • Initial healing period of 4-6 weeks
  • Gradual return to sexual activity
  • Proper device cycling instructions Recovery protocols

Long-term Results

Research shows that proper sizing leads to:

 

  • High patient satisfaction rates
  • Improved quality of life
  • Better functional outcomes Outcome studies

Choosing the Right Surgical Team

The success of penile implant surgery heavily depends on the surgical team's expertise. Patients should seek surgeons who:

 

  • Regularly perform implant procedures
  • Have extensive experience with different implant types
  • Maintain high success rates
  • Demonstrate thorough understanding of sizing techniques
