(036) Outcomes of Penile Prosthesis Implantation after Transgender Phalloplasty: A Single Center Study

Abstract Introduction Many transmen chose to pursue penile prosthesis (PP) implantation as a stage of genital gender affirming surgery. The facilitates penetrative intercourse, the neophallus lacks rigid erectile tissue. While PP placement is well-established and relatively low-risk surgical treatment option for dysfunction cis-male population, published series post-phalloplasty have demonstrated higher rate complications subsequent explant. Objective To demonstrate that an integrated team participates in all stages phalloplasty creation can improve outcomes transmen. Methods We performed retrospective review who underwent at our institution from January 2015 through October 2021, yielding cohort 44 men. Men another reason (trauma, infection, priapism) were excluded. Both malleable (MPP) inflatable (IPP) prostheses included cohort. Home refers institution, outside institution. technique emphasizes exclusion urinary flora operative field avoiding excess anchor material minimize niduses infection. analyzed preoperative, operative, post-operative characteristics, stratified by whether was also logistic regression predictors explant Results Cohort characteristics are represented Table 1. PPs implanted 28 16 Average age 32 33 cohorts, respectively. IPPs more commonly than MPP. Notably, time significantly lower if had been constructed (p=0.014). men total required explant, 7/28 (25%) home group 9/16 (56.3%) group. Predictors explantation shown 2. Significant (p=0.013), smoking (p=0.030), (p=0.007), (p=0.043), number pre-PP revision surgeries (p=0.047). On multivariate including variables significant on univariate analysis, only (p=0.032) (p=0.010) remained predictors. Conclusions present large cohort, demonstrating exceedingly low infection improved both with same team. Our analysis suggests patient influence outcomes. Disclosure No
