[|Human|] I m to have a stent remove from my kidney in the next two weeks. When it was inserted the doctor wasn t sure just what was causing the blockage, but put in a stent anyway. Is this normal? And what can I expect when I have it removed? It has caused me a lot of pain and bleeding.
[|AI|]  Yup, that's quite common in urinary obstruction when no obvious cause is found and people land up having stent in the ureter. Having said that, it is found to deal with many subtle and/or temporary obstructions including cell debris, small kidney stones and so on. Thus, it protects the kidney from permanent damage. But it cants be permanent and once basic problem is solved and obstruction relieved, we can get rid of the stent at any later date before it itself becomes a sides for infection!!!
