Patient: Description of condition (onset, main symptoms, hospital visited, etc.): My father is 57 years old, has a history of hypertension, congenitally has only one right kidney, on May 6, 2010 began to urinate, general edema, examination found intrarenal stones blocking the ureter, through the ureteral ballast lithotripsy failed to place J tube, recommended extracorporeal shock wave lithotripsy. The last ultrasound examination showed that the stone was 12MM * 8MM, acidic stone. Since the J-tube cannot be placed in the body for too long, it has been 2 months since then, but the stone has not been broken to the point where the tube can be taken out and it is afraid of re-stuffing, and open surgery is afraid of sequelae, this problem has been troubling our family. Doctor: If the stone is in the upper part of the ureter, you can consider doing percutaneous nephrolithoscopy to retrieve the stone, no matter what method is used, the stone should be removed as soon as possible. Patient: Thank you for your reply, I have seen many doctors, but they did not mention other methods, they all called extracorporeal shock wave, probably because of one kidney, so they are afraid to do it, is it safe to do percutaneous nephrolithoscopy to remove stones? Patient: Sorry, I was too anxious, I haven’t thanked Dr. Wang yet, thank you very much for taking time out of your busy schedule to reply, I didn’t expect to get a reply from Dr. Wang so soon, I really appreciate it! Doctor: For your father’s disease, the safest choice is to remove the stone as soon as possible. However, even if the doctor is highly skilled, he will not guarantee absolute safety. Flying is also a big risk. Patient: Thank you, Dr. Wang, I am not talking about the safety of this procedure, I believe your hospital has enough mature technology to do this surgery, but I am worried about whether there will be kidney atrophy after this surgery, I have checked online as if someone will be like this, but I don’t know if this result is accidental or inevitable. Recently my father has been losing his appetite for food, he can only drink some porridge and water every day, his body is very weak, today he went for a checkup, the doctor said he has inflammation, he needs to eliminate the inflammation first, I asked the doctor after the inflammation? He also can not set a specific program. Can you do surgery in his case? I’m really worried. I hope Dr. Wang won’t be too annoyed with me. Thank you! Doctor: The chance of this happening is less than one in 10,000, the premise is that there is no other problem with the original kidney. From your description, your father’s disease should be treated as soon as possible. Otherwise, the kidney function damage is more dramatic. Patient: Oh no, I just looked up “uremia” and found that my father has developed nausea, loss of appetite and other symptoms, which seems to be the symptoms of uremia. Can I go to your clinic for treatment? Doctor: . Nausea, loss of appetite and other symptoms are early symptoms of UTI, and it is crucial to remove the obstruction as soon as possible. This is when you need to see our urologist.
