Hi. I am 66 years old had the TURP procedure approx 1.5 years prior to my LRP. I am currently 13 weeks following my surgery and have experienced slow progress. I began to notice improvement after 10 weeks. My improvement at this time were better night sleep with only one urination. Fairly good control in the AM urinating roughly once per hour but really having to concentrate using my pelvic floor muscles to prevent or lessen stress leaks. In the afternoon and evenings, with more activity, there is more leakage. At this point (again 13 weeks) I am using 2 briefs and 4-6 light pads in a 24 hour period. I don't like the discomfort of heavier pads. I am doing Kegels 3-5 times per day, 10 reps long and 12 reps short/quick. I have cut off coffee and drink decaf tea in the AM. I refrain from alchohol 4 nights/week. On nights I do enjoy a beer or glass of wine, leakage does increase!
So to respond to your question, I think that my experience so far is very similar to those who have not had a TURP procedure, possibly a liitle better. Hope this helps. Cheers.
