Development of Nomograms to Predict the Recovery of Erectile Function Following Radical Prostatectomy

Area of Science:

• Urology
• Sexual Medicine
• Oncology

Background:

• Radical prostatectomy (RP) can impact erectile function recovery.
• Predicting recovery is complex due to numerous confounding factors.
• A predictive tool is needed for patient-physician discussions.

Purpose of the Study:

• To develop preoperative and postoperative nomograms.
• To predict erectile function recovery after RP.
• To aid in clinical decision-making and patient counseling.

Main Methods:

• Prospective quality-of-life database utilized.
• Multivariable ordinal logistic regression models employed.
• Nomograms developed using standard preoperative and postoperative factors.

Main Results:

• Three nomograms created: preoperative, early postoperative, and 12-month postoperative.
• Nomograms predict functional erections (IIEF domain score ≥24) and severe ED (≤10) at 2 years post-RP.
• All nomograms demonstrated concordance indexes >0.78 with good calibration.

Conclusions:

• Developed nomograms can assist clinicians in discussing erectile function recovery post-RP.
• These tools enhance accuracy in patient-physician communication.
• Further external validation is recommended.
