I know this is an old thread but I wanted to put the information out for people. 58 year old male urinary retention found incidentally when being reviewed for another condition. Urinary retention we are talking over a liter at times no kidney damage, Urologist afraid if we catheter I’ll never be able to urinate again, fast forward to today what helped was the combination of tamsulosin and acupuncture. Yes acupuncture, there are NIH studies showing very good results- it didn’t completely cure me but I am able to urinate better and actually have the urge at times to urinate which had almost gone away. I have to keep a close watch on getting constipated it really affects the ability to urinate. When I feel I am starting to bloat or get constipated I take mirilax ( non habit forming) and see about going into the acupuncturist for a tune up. I take a fiber pills to help also. I hope this helps someone.

God Bless.
