question: A friend of mine suffers from reoccurring kidney stones. He has had a jj sent set from the kidney to his urinary tract. This was done in July 2014. He should have had it removed least by Nov 2014. He has no muscle control when he needs to urinate. Having to get to a toilet almost immediately. Can the sent be causing any damage? Furthermore, a stone has lodged itself now near tip of his penis; causing immense pain. Can the stone also cause him any damage? He has also had shock wave treatment to break the stones down; but it would seem to no effect. He has been advised to drink plenty of water; and he is currently taking a Internet herbal tablet named Renivive or Cystone to help disorders the stones..but does not seem to be working? He has been taking tramodol to help eliviate the constant pain and a dirretic fusiomide How better to treat he? Please advise? Thank you.
