A recent study evaluates penile prosthesis revision outcomes following phalloplasty in assigned female-at-birth (AFAB) individuals. Specifically, the retrospective cohort analyzed 694 patients over two decades. Consequently, researchers identified significant differences in device longevity and mechanical failure rates between manufacturers. Ultimately, this data is essential for urologists managing gender-affirming surgeries.
Interestingly, the device model served as an independent predictor of mechanical failure. For example, Coloplast implants showed a significantly lower risk compared to Boston Scientific devices (SHR 0.43). However, the time to revision was shorter for Coloplast at 1.4 years versus 3 years for Boston Scientific. Therefore, surgeons must discuss these nuances during preoperative counseling.
Notably, the 15-year cumulative incidence of mechanical failure reached 30.6%. Meanwhile, the overall revision incidence was much higher at 65.1%. Furthermore, factors like phalloplasty type or staged urethroplasty did not significantly impact these rates. Thus, the mechanical integrity of the device remains the primary concern for long-term success.
According to this 15-year study, the cumulative incidence of mechanical failure is 30.6%.
Yes, Coloplast implants demonstrated a lower risk of mechanical failure compared to Boston Scientific devices, though they had a shorter time to revision.
