Introduction: The most prevalent long-term complaint after successful inflatable penile prosthesis (IPP) surgery is reduction of penile length. The purpose of this study was to evaluate penile measurements in patients whose implantation experience included the aggressive new length measurement technique (NLMT) coupled with postoperative IPP rehabilitation (daily inflation) of the implant for 1 year. Moreover, we aimed to document objective data concerning dimensional changes of the phallus over time. Postoperative IPP rehabilitation has been discussed and presented at meetings, but no multi-institutional prospective data have been published.
Aim: Our goal was to assess results using the Coloplast Titan IPP, with NLMT, and postoperative rehabilitation.
Methods: After IRB approval, we conducted a prospective, three-center study of 40 patients who underwent IPP placement, with NLMT for end organ failure erectile dysfunction with the Coloplast Titan IPP. The patient was instructed to inflate daily for 6 months and then inflate maximally for 1-2 hours daily for 6-12 months. Fifteen penile measurements were taken before and immediately after surgery and at follow-up visits.
Main Outcome Measure: Penile length measurements after implantation compared with 12 months postimplantation.
Results: Penile measurement changes were statistically significantly improved at 12 months as compared with immediately postoperative and at 6 months. A total of 64.5% of subjects were satisfied with their length at 1 year, and 74.2% had perceived penile length that was longer (29%) or the same (45.2%) as prior to the surgery; 61.3% and 16.1% of subjects had increased and unchanged satisfaction, respectively, with penile length as compared with prior to IPP surgery. All but two subjects (93.4%) were satisfied with the overall function and dimensions of their IPP.
Conclusion: This study suggests using the Coloplast Titan IPP with aggressive cylinder sizing, and a postoperative penile rehabilitation inflation protocol may help optimize patient satisfaction and erectile penile measurements.

Introduction: Patient medical and surgical history factors, such as prior prostatectomy, may lead surgeons to opt for ectopic reservoir placement rather than the standard reservoir location in the retropubic space (RPS) during inflatable penile prosthesis (IPP) placement.
Objective: To examine the safety and effectiveness of ectopic reservoir placement used with three-piece IPPs in relation to reservoir placement in the RPS.
Methods: A systematic review of MEDLINE/Pubmed and Embase databases was performed for literature between 1970 and 2022.

Article Synopsis
- Penile prosthesis implantation is a surgical option for erectile dysfunction when other treatments fail, but it has potential complications, including high-flow priapism, a rare condition caused by an arteriovenous fistula.
- A 54-year-old male had a 3-piece inflatable prosthesis implanted successfully, but later experienced uncontrolled tumescence, which was diagnosed as high-flow priapism.
- The patient was treated with antiandrogen medication and deflation of the prosthesis for 3 months, resulting in the closure of the fistula without further surgery, emphasizing the need for careful evaluation of symptoms post-implantation.

Devices such as inflatable penile prostheses (IPP) can be used to achieve erectile rigidity after phalloplasty in assigned female at birth (AFAB) individuals. The approach to inserting an IPP in a neophallus is different and more challenging compared to that of an anatomical penis due to the absence of anatomical structures such as the corpora cavernosa, and the more tenuous blood supply of the neophallus and reconstructed urethra. In addition, the ideal surgical techniques and devices for use in the neophallus have not been defined.

Purpose: Glans vascular compromise had previously been considered a rare but devastating complication of the subcoronal incision for inflatable penile prosthesis surgery. Here, we describe the largest series of subcoronal implants to date to assess contemporary complication rates.
Materials And Methods: A retrospective review of subcoronal prosthesis placements by a single surgeon from Seoul, South Korea, was performed.
