Prostatic and pelvic imaging parameters to predict post radical prostatectomy erectile function recovery: a...

Area of Science:

• Urology
• Radiology
• Oncology

Background:

• Radical prostatectomy for prostate cancer can lead to long-term urinary incontinence and erectile dysfunction (ED).
• Predicting functional recovery of erections is vital for patient counseling and timely ED treatment.

Purpose of the Study:

• To systematically review imaging parameters for predicting erectile function (EF) recovery after laparoscopic or robotic prostatectomy.
• To assess the impact of pre- and intraoperative imaging on postoperative EF.

Main Methods:

• Systematic search of publications from January 2000 to December 2023.
• Inclusion of 8 studies using MRI, diffusion tensor imaging (DTI), or intraoperative ultrasonography.
• Formal EF assessment using validated questionnaires at baseline and postoperatively.

Main Results:

• Preoperative MRI parameters like contrast enhancement (Ratio120) and neurovascular bundle (NVB) area showed weak to moderate correlations with EF recovery.
• Diffusion tensor imaging (DTI) parameters related to nerve fiber changes showed weak correlations with EF.
• Intraoperative ultrasound assessment of NVB vessels correlated with postoperative EF.

Conclusions:

• No single imaging parameter strongly predicts EF recovery after prostatectomy.
• Prostate enhancement on mpMRI and intraoperative ultrasound warrant further investigation.
• More research is needed to establish reliable predictive parameters for EF post-prostatectomy.
