Abstract

Objectives: To provide a comprehensive summary of the surgical outcomes of Zephyr Surgical Implants (ZSI; Geneva, Switzerland) hydraulic and malleable female-to-male (FTM) penile implants (PIs) in transgender patients.

Patients and methods: All transgender patients who underwent hydraulic (ZSI FTM 475) and malleable (ZSI FTM 100) erectile device implantation between January 2017 and March 2024 were retrospectively identified. Demographics, perioperative characteristics, postoperative complications, and re-operations were recorded. Postoperative outcomes of malleable and hydraulic PI implantation were compared and risk factors for early and late complications were identified.

Results: A total of 50 transgender patients underwent 85 PI implantation procedures, including 50 primary and 35 secondary implantations. The postoperative infection rate was 15% for hydraulic PIs and 11% for malleable PIs (P = 0.83). In total, 66 hydraulic PIs and 19 malleable PIs were placed. The late complication rate encompassing dysfunction, malposition and erosion was 56% for the hydraulic PIs and 58% for the malleable PIs (P = 0.68), with a median (interquartile range) postoperative follow-up of 26±12 and 32±22 months (P = 0.22), respectively. The explantation-free survival rate at 3 years after implantation of the device was 39% for the hydraulic PIs compared to 31% for the malleable PIs (P = 0.64). Secondary PI implantations were associated with a significantly higher risk of complications compared to primary procedures (odds ratio 3.5, P = 0.03) regardless of the type of PI. Additionally, urethral lengthening increased the likelihood of late complications with a hazard ratio of 2.6 (95% confidence interval CI 1.3-5.0, P = 0.01).

Conclusion: The ZSI FTM PIs display poor 3-year complication-free survival despite being tailored for implantation after phalloplasty. There were no significant differences in short- and long-term complication rates between malleable and hydraulic PIs. Notably, secondary PI implantation and urethral lengthening were linked to a significantly increased risk of late complications.

变性人阴茎成形术后液压和可塑的女性到男性阴茎植入物:回顾性队列分析。
目的:全面总结Zephyr外科植入物(ZSI; Geneva, Switzerland)在跨性别患者中使用液压和可塑女变男(FTM)阴茎植入物(pi)的手术效果。患者和方法:回顾性分析2017年1月至2024年3月期间所有接受液压(ZSI FTM 475)和可拉伸(ZSI FTM 100)勃起装置植入的变性患者。记录人口统计学、围手术期特征、术后并发症及再手术情况。比较可塑和液压PI植入术的术后效果,并确定早期和晚期并发症的危险因素。结果:共有50名变性患者接受了85例PI植入手术,其中50例为原发性植入,35例为继发性植入。液力pi术后感染率为15%,可塑pi术后感染率为11% (P = 0.83)。共放置了66个液压pi和19个可锻铸pi。包括功能障碍、错位和糜烂在内的晚期并发症发生率,液压式pi为56%,可锻压式pi为58% (P = 0.68),术后中位(四分位数范围)随访时间分别为26±12个月和32±22个月(P = 0.22)。液压pi植入后3年的无解释生存率为39%,而可锻压pi为31% (P = 0.64)。无论PI类型如何,与首次手术相比,二次PI植入的并发症风险明显更高(优势比为3.5,P = 0.03)。此外,尿道延长增加了晚期并发症的可能性,风险比为2.6(95%可信区间CI 1.3-5.0, P = 0.01)。结论:尽管为阴茎成形术后植入量身定制了ZSI FTM pi,但其3年无并发症生存率较差。可塑性和液压性pi的短期和长期并发症发生率无显著差异。值得注意的是,继发性PI植入和尿道延长与晚期并发症的风险显著增加有关。
