Erectile Function Recovery after Radical Prostatectomy in Men with High Risk Features

Area of Science:

• Urology
• Oncology

Background:

• Radical prostatectomy is a primary treatment for prostate cancer.
• High-risk prostate cancer presents unique surgical challenges regarding tumor excision and functional preservation.

Purpose of the Study:

• To evaluate the efficacy of radical prostatectomy in achieving complete tumor excision and preserving erectile function in high-risk prostate cancer patients.
• To assess the feasibility and outcomes of tailored neurovascular bundle preservation during radical prostatectomy for high-risk cases.

Main Methods:

• Retrospective review of 584 high-risk prostate cancer patients (PSA ≥ 20 ng/ml, clinical stage T3+, Gleason grade 8-10) undergoing radical prostatectomy (2006-2012).
• Analysis of preoperative factors influencing neurovascular bundle preservation probability.
• Assessment of positive surgical margin rates and erectile function recovery in patients with preserved neurovascular bundles.

Main Results:

• Neurovascular bundles were preserved to some degree bilaterally in the majority of patients.
• Lower probability of preservation was associated with Gleason grade 5 and clinical stage T3 disease.
• Among those with preserved bundles, 24% had positive surgical margins, and 47% of men with preoperatively functional erections recovered function within 2 years.

Conclusions:

• Complete bilateral neurovascular bundle resection is not always necessary for high-risk prostate cancer.
• High-volume surgeons can safely perform partial neurovascular bundle preservation in most high-risk patients, maintaining acceptable oncological outcomes.
• Radical prostatectomy offers a significant chance of erectile function recovery for high-risk patients with pre-existing erectile function.
