Patient: He was seen on June 21, 07 for urinary stones, hydronephrosis and small cysts with severe pain. After several treatments by lithotripter, the stones were basically eliminated. However, the two kidney cysts were enlarged, the right kidney 6*4,5CM, the left kidney is smaller, the prostate 4,3*3,3CM, see the attached diagnosis report for details. The doctor is now suggesting that surgery is necessary to cure the problem. 2. Are there any after-effects of surgery? 3. After surgery, if there are stones in the future, can we still use a lithotripter to break the stones, or is surgery necessary? Yang Dongrong: Generally speaking, if the diameter of kidney cyst is more than 5cm, it is better to have surgery. Medication is not effective. Surgery can be done by minimally invasive laparoscopic surgery. It is very safe. If there is a combination of urinary stones, it depends on the specific site. Ureteral stones can be treated by lithotripsy. Kidney stones are best not to be lithotripsy before cyst treatment to avoid cyst rupture and bleeding. Patient: Dr. Yang: Thank you very much for replying to your question in your busy schedule! There are still a few questions I would like to ask you: 1. At present, no stone can be formed because I got a stone last year and it was gradually eliminated by lithotripsy. After the cyst is eliminated, if the stone recurs, is it possible to have extracorporeal lithotripsy? 2.Both sides have cysts, should I have surgery on the big one and should I have surgery on the small one? 3. What is the treatment level of Zhangjiagang First People’s Hospital in this area? Is the level of minimally invasive laparoscopic surgery OK? Is it possible to have surgery in Zhangjiagang? 4.After the cyst is eliminated, is there a high probability of recurrence? Thank you! Yang Dongrong: (1): After the kidney cyst is cured, if the kidney stone recurs, it should be possible to treat it with ESWL. (2): If both sides of the kidney cysts want to operate, it is recommended to use transabdominal laparoscopic technique, which can be solved at the same time (of course, it needs to be determined according to the specific location of the cysts on both sides). (3): How is the level of minimally invasive in Zhangjiagang First People’s Hospital, there is no specific communication, it is not very clear. (4): The chance of recurrence is not high after a single cyst is de-topped. Patient: Dear expert: Hello! There are some people who say that nothing is wrong with this current condition, but what will happen if it is not treated surgically? Thank you! Yang Dongrong: The key depends on the growth site of the cyst and the pressure on the kidney, sometimes there may be cyst bleeding, infection, combined hypertension, and renal function damage. Patient: Doctor: Hello! Is the method of puncture injection of sclerosing agent OK? Some people say it is also better? Thank you Yang Dongrong: The method of injecting sclerosing agent to treat simple renal cysts depends on the specific site of the cyst, and is mostly used in cases where surgery is contraindicated, where there is kidney bleeding and the possibility of infection, and where recurrence is easy after treatment. Patient: If the puncture pierces through the kidney, will it affect the kidney seriously? The doctor said it will recover in 2-3 days, is that right? Thank you Yang Dongrong: It depends on the degree of damage to the kidney, the light ones will recover. In severe cases, the kidney will bleed profusely and need to be embolized to stop the bleeding.
