Penile length alterations following penile prosthesis surgery.
OBJECTIVE
Determine the impact of penile prosthetic surgery on penile length.


METHODS
Stretched flaccid penile length was measured in men undergoing first-time penile implant surgery. Measurements were done before implantation and at 1 and 6 mo postoperatively. Patients were evaluated by the International Index of Erectile Function (IIEF) preoperatively and the IIEF and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) at 6 mo postoperatively. Patients also provided subjective assessment of penile changes at 6 mo postoperatively. Preoperative and postoperative IIEF and EDITS scores were compared as were the patients who complained of penile length loss with those who did not.


RESULTS
Of the 56 patients, 50% were diabetic and 28.5% had previous radical prostatectomy; 78% of the implants were three-piece (Alpha-1, Mentor) and 22% were two-piece (Ambicor, American Medical Service). There were no statistically significant differences in penile length after the surgery compared to preoperative measurements. Forty of 56 patients (72%) reported a decrease in penile length, 10 of 50 (19%) reported no change, and 6 of 56 (9%) had a slight increase. Subjective penile length loss was more common in patients who had undergone radical prostatectomy before prosthesis implantation (32%). No statistical difference in EF domain scores occurred between patients who complained of penile length loss and those who did not; however, men complaining of length loss had lower IIEF satisfaction domain and EDITS scores.


CONCLUSIONS
Penile prostheses do not have a negative impact on measured stretched flaccid penile length. Treatment satisfaction scores do not depend on subjective penile length loss.
