Penile length is preserved after implant surgery

Area of Science:

• Urology
• Andrology
• Surgical Innovation

Background:

• Patient dissatisfaction after penile implant surgery (PI) is often linked to perceived penile shortening.
• Preoperative stretched penile length is hypothesized to approximate postoperative erect length, but data is limited.

Purpose of the Study:

• To prospectively investigate the correlation between preoperative penile dimensions and erect size after PI.
• To determine if PI surgery leads to a decrease in penile length or girth.

Main Methods:

• Standardized measurements of stretched penile length and girth were taken preoperatively and postoperatively in the erect state.
• Data on PI type, comorbidities (BMI, hypertension, diabetes, Peyronie's disease), and prosthesis dimensions were recorded.

Main Results:

• A total of 133 patients were assessed. Mean preoperative stretched length was 12.8 cm, increasing to 13.1 cm postoperatively.
• Mean flaccid girth increased from 10.3 cm to 11.3 cm postoperatively.
• Inflatable penile prosthesis (IPP) resulted in greater length and girth increases compared to malleable penile prosthesis (MPP); comorbidities did not affect outcomes.

Conclusions:

• Penile implant surgery does not significantly decrease penile size; preoperative and postoperative erect dimensions correlate well.
• Comorbidities such as hypertension, diabetes, and Peyronie's disease did not impact surgical outcomes.
• Preoperative measurement and patient agreement on penile dimensions may enhance satisfaction with PI surgery.
