AI Article Synopsis

  • The study aimed to evaluate the impact of the AUA Best Practice Statement on antibiotic use for inflatable penile prosthesis surgeries after its release in April 2008.
  • Researchers analyzed data from over 26,500 patients to track adherence to AUA guidelines and observed a 42% increase in the use of recommended antibiotics post-publication.
  • Results indicated that higher adherence rates were associated with surgery performed by experienced surgeons, while nonadherence did not significantly affect the risk of device explantation within 90 days.

Article Abstract

Objective: To assess changes in antibiotic prophylaxis for inflatable penile prosthesis surgery following publication of the American Urological Association (AUA) Best Practice Statement in April 2008.

Materials And Methods: The Premier Healthcare Database was queried for inflatable penile prosthesis surgeries from January 2000 to March 2020. The primary outcome was administration of an AUA-adherent antimicrobial regimen and secondary outcome was 90-day explant. Piecewise linear regression was used to compare antimicrobial trends before vs after guideline publication. Multivariable logistic regression models were constructed for primary and secondary outcomes.

Results: A total of 26,574 patients who underwent inflatable penile prosthesis surgery were identified, of whom 17,754 (67%) received AUA-adherent antibiotics. After guideline publication, there was a 42% relative increase in AUA-adherent regimen usage, with an increase in the usage trend on piecewise linear regression (from 0.1% to 0.8% of encounters per quarter, R = 0.75, P < .001). Increased usage trends were also observed for gentamicin (from 0.0% to 1.0% of encounters per quarter, R = 0.84, P < .001) and vancomycin (0.1%-0.7%, R = 0.77, P < .001). On multivariable regression, odds of AUA-adherence increased after guideline publication (OR: 1.67, 95% CI: 1.54-1.80, P < .001) and with surgery by a high-volume surgeon (OR: 2.21, 95% CI: 2.07-2.35, P < .01). Nonadherence to an AUA-recommended regimen with use of nonstandard antibiotics (OR: 1.16, 95% CI: 0.78-1.71, P = .5) or excess antibiotics (OR: 0.91, 95% CI: 0.62-1.30, P = .6) was not independently associated with increased risk of 90-day explant.

Conclusions: Publication of the AUA Best Practice Statement was associated with subsequent increases in the usage of guideline-adherent antibiotic regimens, particularly vancomycin and gentamicin, despite absence of level-1 evidence supporting this combination.

Implantation of inflatable penile prosthesis should be considered as a definitive treatment of erectile dysfunction. However, the sole procedure might not allow for optimal dimensional and functional outcomes. The aim of this study was to systematically review the literature and present the findings on the optimal choice of perioperative methods, surgical techniques, and pharmacotherapy to improve penile length, curvature, and erectile function.

Background: Inflatable penile prosthesis (IPP) insertion is recommended for the treatment of patients with Peyronie's disease (PD) and significant erectile dysfunction (ED); adjunctive procedures can be used for residual curvature after IPP placement.

Aim: To assess the management of penile curvature correction in PD patients undergoing IPP procedures within a large multinational, multicenter cohort.

Methods: A retrospective analysis was conducted on PD patients treated with IPP by 11 experienced prosthetic surgeons.

Penile prosthesis implantation is considered a last-resort treatment for erectile dysfunction, used when pharmacological and other conservative treatments are inadequate or at the patient's request. The well-documented complications of penile prostheses include pain, infection, mechanical failure, improper positioning, and erosion. In this case, we report a patient presenting with penile skin necrosis, despite the absence of typical risk factors such as diabetes mellitus, atherosclerosis, or chronic renal failure, attributed to pressure from a condom catheter that was used 15 years after the inflatable penile prosthesis implantation.

Background: Rigicon is a newer inflatable penile prostheses (IPP) manufacturer that has produced the Infla10 IPP for countries outside the United States (US) since 2019, with Food and Drug Administration studies for approval of Infla10 in the US presently underway.

Aim: This study aims to report the first patient satisfaction, efficacy, and safety from revision data for the newly available Rigicon Infla10 IPP.

Methods: A single surgeon's first 58 patients who underwent Rigicon Infla10 IPP implantation between 2019 and 2023 were included.
