Introduction: The two-piece inflatable penile prosthesis (IPP; Ambicor) might be a preferred option for men with erectile dysfunction (ED) who have significant retroperitoneal scarring, limited manual dexterity, or other issues. There are reported differences in outcomes and patient and partner satisfaction between three-piece and two-piece IPPs. Aim: To report contemporary outcomes, patient and partner satisfaction, and mechanical durability data of the two-piece compared with the three-piece IPP. Methods: A PubMed search was performed related to two-piece penile prostheses. Emphasis was placed on perioperative outcomes and patient and/or partner satisfaction scores. Non–English-language articles were excluded. Main Outcome Measures: Use of the Ambicor two-piece penile prosthesis was assessed by outlining the contemporary literature. The etiology of ED in this population, mechanical attributes, penile morphologic changes, satisfaction, and its use in special populations were reviewed. Results: The most common etiology of ED for placement of the device remains a vasculogenic cause (range = 11–62%). Overall complication rates were 2.1% to 11.2% for the general population. Mechanical failure was seen in 0.7% to 6.1%. Infection rates were 0.7% to 4.8%. Spontaneous deflation was seen in approximately 25%. Higher complication rates were found in transgender patients after neophallus creation and the two-piece IPP could offer better durability compared with the three-piece IPP. Longer operative times, greater use of advanced dilation techniques, and greater length loss also have been reported. Overall satisfaction rates are higher than 85%. Conclusion: The predominant etiology of ED for two-piece penile prosthesis placement is vasculogenic. There is a trend toward IPP insertion in patients after radical prostatectomy or who have spinal cord injury. The two-piece device has similar complication rates and high patient satisfaction scores compared with three-piece IPPs. Further larger prospective studies are needed to validate our findings, resolve discrepancies in published outcomes, and contribute to the sparse data on this subject. Ko OS, Bennett NE.
