E-PASS Scoring System in Predicting Postoperative Complications After Penile Prosthesis Implantation

Area of Science:

• Urology
• Surgical Oncology
• Anesthesiology

Background:

• Penile prosthesis implantation (PPI) surgery can lead to various complications, including infection, tissue damage, device failure, and patient dissatisfaction.
• Currently, no established scoring system effectively assesses both preoperative physical status and intraoperative risk factors for PPI complications.

Purpose of the Study:

• To evaluate the feasibility and reliability of the Estimation of Physiologic Ability and Surgical Stress (E-PASS) scoring system in predicting postoperative complications following penile prosthesis implantation (PPI).

Main Methods:

• A single-center retrospective study analyzed data from 56 patients who underwent PPI between 2015 and 2024.
• Demographic, preoperative, and intraoperative data were collected to calculate E-PASS scores and sub-scores.

Main Results:

• Postoperative complications occurred in 30.4% of patients.
• Patients with complications exhibited higher E-PASS scores (preoperative risk, surgical stress, and comprehensive risk scores [CRS]).
• A CRS cut-off of -0.1238 demonstrated significant predictive value (AUC = 0.75), with scores above this threshold increasing complication risk 16.2-fold.

Conclusions:

• The E-PASS scoring system is a reliable tool for predicting postoperative complications in patients undergoing penile prosthesis implantation (PPI).
• Its ability to integrate both preoperative physical condition and intraoperative risk factors enhances its utility in risk stratification for PPI.
