(287) A Patient's Journey with Erectile Dysfunction: Prediction Progression to Penile Implant

Abstract

Abstract Introduction Inflatable penile prosthesis (IPP) is seen as the gold standard for surgical treatment for ED, specifically for patients that are not amenable to lifestyle changes or oral medications. Objective This study aims to explore which patients progress to seeking treatment with an IPP along their journey with erectile dysfunction. Methods This retrospective study identified patients with ED as a chief complaint during the primary visit or follow-up from 2009-2022. If patients eventually progressed to treatment with IPP, data was collected to find common features and analyzed. Results Of our cohort of 361 men presenting with erectile dysfunction (ED), 21 men progressed to the placement of an inflatable penile prosthesis (IPP). 20 men classified as non-Hispanic, with 13 white, 6 African American/black, and 1 Asian males. Only 1 man was Hispanic. 5 men had either hypertension (n = 11), hyperlipidemia (n = 10), or DM (n = 3), with 6 having both hypertension and hyperlipemia, 1 with hypertension and diabetes, and 1 with hypertension, hyperlipidemia, and diabetes. Median age of the group at surgery was 76 years (IQR: 71 – 82), with median time from initial presentation to surgery of 12 (IQR = 11.5-27.5) months. N = 10 men had trialed oral phosphodiesterase inhibitor type 5 (PDE-5i) therapy, and 7 men failed intracavernosal injection (ICI) therapy. 8 men had been treated for hypogonadal symptoms with testosterone replacement therapy (TRT). Of patients who had data available on their reason for IPP placement, indications included were Peyronie’s disease inhibiting intercourse (8/21), longstanding ED refractory to medical therapy (4/21), post-prostatectomy ED (4/21), history of priapism requiring surgical intervention (1/21), and history of spinal cord tumor (1/21). Among those treated with IPP, the median patient waited almost 1 year from initial presentation following failure with PDE5i, ICI, and TRT. 17/21 men reported satisfaction after IPP treatment. In those who progressed to IPP, the majority of indications were organic forms of ED (Peyronie’s disease, neurogenic, surgery). Conclusions Only 5.8% of men in this cohort went on to proceed with an IPP. In summary, our results indicate that IPP is best suited for those presenting with organic ED who have failed more conservative management techniques. Further studies are needed to assess why so few men go on to proceed with an IPP and wait an average of 2 years.
