Frequency needing a pee

Hi

Currently I am needing a pee every couple of hours day and night.

This has been going on now for two or three years and was the reason I went to the Dr in the end to find out I had PC.

I've had radiotherapy and continuing with HT I wouldn't say it has got any worse during or after my treatment but it is is starting to completely dominate my life at the moment.

I met with my Urologist a couple of months back and HD prescribe me solifenacin for over active bladders but that hasn't changed anything. 

I'm back with him next week after a bladder scan and flow test.

I have tried the bladder retraining programme for the last couple of months but that hasn't really helped do far

Has anyone else had a similar experience and ot questions/suggestions I can put to the urologist??

Thanks
