Inflatable penile prosthesis implant length with baseline characteristic correlations: preliminary analysis of the...

Area of Science:

• Urology
• Andrology
• Surgical Outcomes Research

Background:

• The Prospective Registry of Outcomes with Penile Prosthesis for Erectile Restoration (PROPPER) study investigates real-world outcomes of penile implant surgery.
• Understanding factors influencing penile prosthesis size is crucial for patient counseling and surgical planning.

Purpose of the Study:

• To prospectively correlate patient comorbidities and demographics with implanted penile prosthesis size.
• To enable clinicians to better predict implanted penis size following penile implantation.

Main Methods:

• Prospective collection of patient demographics, medical history, and surgical details.
• Utilized Pearson correlation coefficient and multivariate analysis to identify predictors of implanted prosthesis length.
• Included data from 1,135 men undergoing primary penile prosthesis implantation between June 2011 and June 2017.

Main Results:

• Implant length showed weak negative correlations with White/Caucasian ethnicity, history of radical prostatectomy (RP), and comorbidities like Peyronie's disease (PD).
• Weak positive correlations were observed with Black/African American ethnicity, cardiovascular disease (CV disease) as an ED etiology, and pre-operative stretched penile length.
• A moderate positive correlation was found between implant length and pre-operative flaccid penile length.

Conclusions:

• Implanted penile prosthesis length is negatively associated with certain ethnic groups, history of prostatectomy, and incontinence.
• Positive correlates for implant length include cardiovascular disease, and pre-operative flaccid and stretched penile lengths.
• These findings provide valuable insights for predicting penile implant size in clinical practice.
