Hi, I'm Beth. My niece recently had a kidney stone which was stuck between her urethra and her bladder. Surgery was performed to remove it & a stent was inserted. Having extreme pain the next morning, she was rushed to the hospital. She was told her body rejected the stent, so it was removed and she was sent home. She had more pain, went back to the hosp. and they said it was from the inflammation, so she was given both anti-inflammatory & pain meds..In the middle of the night she was rushed back to the hosp with severe back & leg pain. She was then diagnosed with a blood clot @ the base of her lung & is now still in the hosp on Heparin, getting better & told she will be sent home with Lovenox injections. Could these two incidents be related in some way? Could the surgery have caused an embolism to occurr? I would appreciate any light you can shed on this whole thing. I am very concerned for her parents are both sick ,My sister, the patient's mother has Ovarian cancer, & the father has Bladder Cancer.
