“…DeLay et al in their study included 65,448 IPP implantation cases between 2000 and 2015, and revealed that the use of RTE significantly increased revision rate (1.34% vs. 2.65%) [20]. Moreover, Thirumavalavan et al showed in a laboratory study [21] and in a review article [22] that limiting the use of RTE results in more natural erectile quality because the RTEs are not involved in penile rigidity during inflation of the device. By increasing the length of RTE, the authors demonstrated in a lab model that IPP bending deflection increased, which was correlated with a decrease in axial rigidity [21].…”

Literature concerning corporotomy location in multicomponent inflatable penile prosthetic surgery via a penoscrotal approach is scarce if not nonexistent. Aim of our study was to report practices in low-, moderate-, and high-volume penile implant centers regarding corporotomy location and evaluate its potential impact on intraoperative and short-term postoperative complications. Data from 18 (13 European and 5 American) implant centers were collected retrospectively between September 1st, 2018 and August 31st, 2019. Variables included: intraoperative proximal and distal corpus cavernosum length measurement, total corporal length measurement, total penile implant cylinder length, and length of rear tip extenders. Eight hundred and nine virgin penile implant cases were included in the analysis. Mean age of participants was 61.5 ± 9.6 years old. In total, 299 AMS 700™ (Boston Scientific, USA) and 510 Coloplast Titan® (Minneapolis, MN USA) devices were implanted. The mean proximal/distal corporal measurement ratio during corporotomy was 0.93 ± 0.29 while no statistical difference was found among low-, moderate-, and high-volume penile implant centers. A statistically significant correlation between lower proximal/distal measurement ratio and higher age (p = 0.0013), lower BMI (p < 0.0001), lower use of rear tip extenders (RTE) (p = 0.04), lower RTE length (p < 0.0001), and absence of diabetes (p = 0.0004) was reported. In a 3-month follow up period, 49 complications and 37 revision procedures were reported. This is the first study reporting the current practices regarding corporotomy location during IPP placement in a multicenter cohort, particularly when including such a high number of patients. Nevertheless, the retrospective design and the short follow up period limits the study outcomes. Corporotomy location during penoscrotal IPP implantation does not correlate with intraoperative or short-term postoperative complication rates. Future studies with longer follow up are needed in order to evaluate the association of corporotomy location with long-term complications.

Background and Objective In contemporary Urology, the gold standard for treatment of erectile dysfunction refractory to medical therapy has been implantation with a penile prosthesis. The past 40 years has witnessed evolutions in technology and surgical techniques, which have led to increased patient satisfaction rates and decreased complication and infection rates. This review is an update to a prior review article that evaluates these advancements in the context of patient satisfaction and different rates of complications following surgeries. In addition, the review compares malleable and inflatable prostheses with regard to infection rate, mechanical failure rate, and erosion rate. Methods A literature search was conducted using Medline and Google Scholar to examine papers from 1973 to the present day. Keywords, such as, “penile prosthesis surgery”, “malleable penile prosthesis”, “inflatable penile prosthesis”, “two-piece Inflatable Penile Prosthesis (IPP)”, and “three-piece IPP” were utilized during the search. A total of 76 papers were included, and all were in English. Key Content and Findings Studies on the latest models of each of the three prostheses (malleable, two-piece IPP, three-piece IPP) revealed patient satisfaction ratings at or above 75%. Both types of IPPs were associated with greater satisfaction and lower erosion rates while malleable prostheses were associated with lower mechanical failure rates. Although no significant differences in infection rates were noted between the prosthesis types, a history of diabetes, obesity, and smoking were predictive of infection events. Conclusions The three-piece IPP, if indicated for a suitable patient, is generally accepted as the best type of prosthesis given its biological mimicry to an erect human penis.

Over the past 40 years, the technological and surgical advancements in penile prostheses have led to increased patient satisfaction rates and decreased complication and infection rates. In cis males with erectile dysfunction (ED), these technological improvements tremendously improve quality of life. In female to male transgender patients, prostheses provide the ability to engage in penetrative intercourse and to urinate standing. This review evaluates technological and surgical advancements in penile prosthetics in the context of documented patient satisfaction and complication rates from prosthesis surgeries. Retrospective studies of penile implant usage in female to male gender-affirming surgeries report that infection and complication rates are higher than those seen in cis males. There are newer prostheses developed specifically for female to male reassignment surgeries, but outcome data is limited. Continued research and development are needed to develop more efficacious penile implantation options for gender affirmation surgery.
