Sorry you are suffering from the BPH. I had it for 15 years prior to my pCa. I personally don't think there's any natural things that would be as effective as the drugs your are being prescribed, sorry. At my worse, I never had any surgical procedures to ease the situation. There's the roto-rooter that reams out the channel, but I didn't have that. There's several others with more practical experience with different treatments , they can help, probably. Check back and see if anyone responds.
