Patient: My father is 76 years old and has been suffering from kidney stones on both the left and right side for more than 20 years, which are fine sand stones. In October of this year, he had an attack of kidney stones on his left side with hematuria, and was found to have prostate calcification. The ultrasound examination showed that both the left and right sides had stones with calcification of the prostate. Another note: My father has a history of diabetes for more than 20 years. Now after treatment (pain relief – 6542, hemostasis – Anluo blood, money grass punch) although the symptoms are reduced, but the symptoms of frequent and urgent urination are still more obvious. I don’t know what should be the next treatment? Doctor: Fine sand-like stones are usually fine as long as you drink more water, it will not cause serious renal colic and affect the kidney function. However, you should pay attention to drink more water, around 3000-3500ml per day. This will ensure that the stones will not get bigger and bigger and cause poor kidney function. There are many reasons for frequent urination, your father’s prostate itself can cause frequent urination, in addition to diabetes can also cause frequent urination, in addition to in the development of renal colic, frequent urination is also going to appear, therefore, from the information you provided it is difficult to determine which cause is caused. You can take some medications for frequent and urgent urination, including Cordova or Ning Ju Tai, etc., which are effective.
