My husband suffered a heart attack on june 2, and his angioplasty was done. After that his creatinine levels were high so we got the sonography done which showed stones in both kidneys and the stone in right kidney was obstructing the ureter. Since doctor could not perform the operation as ecosprin is prescribed, he put a stent in the ureter through rirs. Now I am looking for options of further treatment as the stent that was planted in the kidney has expired.
