Patient: Description of condition (onset, main symptoms, hospital visited, etc.): Patient male. 23 years old. The stone was found 6 years ago. Because the family situation is not good. General hospital is not good. All mind me to go to a large hospital. The hospitals I visited were Hunan Xiangya Hospital, South Lake Hospital. Huadu Chinese Hospital are not very good. Are drug treatment. The situation has not improved. Do you mind if I go to those hospitals. What are some ways to treat my disease. Am I close to kidney failure? To accurately determine renal function, blood needs to be drawn to check creatinine and urea nitrogen. If creatinine is less than 200, intravenous pyelogram can be performed to determine whether there is obstruction in the ureter and the cause of obstruction. You must receive early surgical treatment, preferably percutaneous nephrolithotomy and minimally invasive means to resolve ureteral obstruction at the same time, otherwise you will definitely develop chronic renal insufficiency (i.e. renal failure) and uremia.
