my husband just had his catheter removed today. Now, when he urinates, he has extreme, deep pain in his right kidney area (only while urinating). Not sure if he is urinating enough. He has a stent in his ureter and the doctor says that because the ureter is not able to close because of the stent, that the urine is pushed back up into the kidney creating the pain. Wondering if he should have kept the catheter in while he has the stent?
