Summary
Radical prostatectomy (RRP) in men eliminates age-related declines in peak urinary flow rates (PFR) and voided volumes. Post-surgery, urinary function remains stable, unlike in aging men without prostate removal.
Area of Science:
- Urology
- Men's Health
- Surgical Outcomes
Background:
- Age-related decline in peak urinary flow rates (PFR) and voided volumes is a common concern for men over 40.
- Radical prostatectomy (RRP) is a surgical procedure for prostate removal.
Purpose of the Study:
- To investigate the impact of radical prostatectomy (RRP) on age-related changes in peak urinary flow rates (PFR) and voided volumes.
- To compare urinary function post-RRP with community-based data on aging men.
Main Methods:
- Evaluated 100 men 1-9 years after RRP.
- Assessed PFR, voided volume, post-void residual, and AUA symptom score.
Main Results:
- Mean PFR post-RRP was 26.6 cc/sec and mean voided volume was 345 cc.
- PFR and voided volume remained stable with age and follow-up duration.
- Post-RRP PFRs were significantly higher than those reported in age-matched community-based studies.
Conclusions:
- Radical prostatectomy (RRP) results in higher PFRs compared to historical controls.
- Urinary function, including PFR and voided volume, remains stable with age after RRP.
- Total prostate removal appears to eliminate the age-related reduction in PFR and voided volumes observed in the general male population.
