Nerve-sparing prostatectomy and urinary function: a prospective analysis using validated quality-of-life measures

Area of Science:

• Urology
• Oncology
• Quality of Life Research

Background:

• Radical prostatectomy for prostate cancer can impact post-operative urinary function.
• Neurovascular bundle preservation is a key surgical consideration during radical prostatectomy.

Purpose of the Study:

• To prospectively evaluate the relationship between the extent of neurovascular bundle preservation during radical prostatectomy and subsequent urinary function and bother.
• To utilize validated quality-of-life questionnaires to assess patient-reported outcomes.

Main Methods:

• A prospective study of 91 patients undergoing radical prostatectomy.
• Patients were categorized into >50% nerve sparing and <=50% nerve sparing groups.
• Urinary function and bother were assessed using the UCLA Prostate Cancer Index and International Prostate Symptom Score, with adjustments for preoperative factors using linear mixed models.

Main Results:

• 68% of patients had >50% nerve sparing; 32% had <=50% nerve sparing.
• Increased nerve sparing was significantly associated with better urinary function (P = .014) and less urinary bother (P = .043).
• Adjusted analysis showed the >50% nerve-sparing group had higher urinary function and bother scores compared to the other group.

Conclusions:

• Nerve-sparing radical prostatectomy is associated with improved urinary function and reduced urinary bother.
• The observed improvements in urinary outcomes were modest.
• The clinical significance of these modest improvements requires further investigation.
