After a successful surgery, the patient enters the lithotripsy stage, how can we speed up the process? This is clear to all patients – drink more water and be more active, but of course, sometimes you can’t be too hasty. If the road is not wide, but the cars go one by one in an orderly way, all the cars can move and they are not slow; but if there is no order, all the cars are jammed into the road at once, and eventually one car can’t move. It is the same when draining stones, just dealing with a 5 mm stone, the patient needs to jump, bounce, and drink more water, let alone after the surgery when he may have to face 100 stones of 1 mm (hypothetical), more exercise and more water is needed. Suppose the stone was very large before surgery, and it was broken during surgery, and the result was satisfactory, but more debris appeared, and we have to let it out little by little in a step-by-step manner. If the preoperative stone is not large, for example, only one centimeter, and the stone is broken at the time of surgery, it will be completely emptied in a week or two by going home and drinking more water and being more active. The width of the ureter should also be taken into consideration. Some people have a wide ureter, which is very fast to drain stones, while others have a narrow ureter, which is not pathologically narrow, but is congenitally narrow, so it will also be slow to drain stones. There are many factors that affect stone removal after surgery. Some people have very large stones, but the effect is very obvious after the operation, and they are emptied very quickly, while some people have very small stones, but they are not slow to drain after the operation. However, one thing is to drink more water, preferably two to three liters of pure water per day, not mineral water or water boiled at home, and to exercise appropriately to promote drainage. Some patients have inquired about hematuria after surgery, is this due to surgical failure? Hematuria is an extremely common concomitant symptom of urologic lumpectomy. There are many reasons for hematuria. It is normal to have blood in urine just after surgery because lumpectomy can cause some mucosal damage to the urinary tract, and the hematuria will disappear naturally in a day or two after surgery. In fact, 4 ml of blood in 1 liter of water can cause the redness of the urine pattern seen by the naked eye. Unless the urinary hematuria is very serious, even bleeding clots, then you should go to the hospital quickly to see what the cause is and whether it needs to be treated. Many patients feel back pain after surgery, is it because the treatment is not complete and the stones are not removed completely? Lithotripsy is not stone removal, there must be stone debris that needs to be discharged by the patient, during this process if all the debris comes out at once and blocks the ureter, there will be pain. If the blockage is so severe that the patient will experience severe renal colic, like the severe pain of a stone attack, then the patient needs to go to the hospital to deal with it. Will the stone recur after surgery, and what should I do if it recurs? This involves a problem of perception, stones are a chronic disease, not that it takes a long time for this stone to grow out, but the so-called slow disease may be repeated. Because many factors that cause stones cannot be avoided, such as anatomical factors (stenosis), metabolic factors (having metabolic diseases such as gout) or environmental factors (hot weather), we cannot avoid them, which means that although the stone was removed this time, the cause of the stone was not touched and it may grow again. Therefore, we should look at stones as if they were a chronic disease, and many of them will grow even after they are removed.
