A prospective study of 1,788 men who underwent RP found that men who had clinically significant LUTS preoperatively experienced a decline in LUTS severity and remained stable over a 10-year interval, researchers reported. Prior studies have shown a progressive increase in LUTS for aging men with an intact prostate.

One of the areas that is affected after prostatectomy is urinary function. Men are counseled that there will be urinary leakage (incontinence) after surgery.
I have been telling men for over 10 years that their urinary stream will improve and bothersome urinary symptoms of frequency and a slow stream would be improved in the long term. This study followed men for 10 years and showed that men have less urinary problems compared to men who never had prostate problems. The reason for this is that men have an enlarging prostate as they get older. This causes a smaller opening for the bladder to empty through. Once the entire prostate is removed, there is a benefit of not having the prostate and resultant obstruction.
