Recently, a senior VIP patient underwent minimally invasive prostate surgery in our department, recovered well 3 days after the surgery, and was ready to remove the urinary catheter, when he suddenly developed significant hematuria again in the morning after bowel movement. This is a rare occurrence, but when it happens, patients are a bit nervous. Today, I would like to take this platform to introduce the postoperative situation of transurethral resection of the prostate, so as to facilitate the subscribers to understand the situation. Prostate electrosurgery is performed by a urologist using special surgical instruments to remove the prostate tissue piece by piece through the urethra, and then finally flushing out the broken tissue with a special flushing device. Therefore, at the end of the operation, the urethra that passes through the prostate has been cut by the electrosurgical knife, and what remains is a fresh, hemostatic wound, which is just located inside the urethra and is invisible to the patient. It takes time for the wound to heal after ECT, just as it does for injuries to other parts of the body, and then problems such as hematuria, frequent urination, urgency, and painful urination may occur before it is fully healed. In most patients, the urine that drains from inside the urinary catheter after electrolysis is red in color. After flushing, hemostasis and other treatments, the color of urine usually turns to light red or close to normal after 2 to 3 days. However, there are a few patients who will suddenly develop hematuria after their condition is stabilized or even after they are discharged from the hospital. This is mainly due to the bleeding caused by the wound inside the urethra which is not fully grown or the scabs formed on the surface of the wound fall off after the prostate gland is electrocuted. Especially when straining to pass stool, it often causes this situation. Therefore, after prostatectomy, it is necessary to maintain soft or mushy stools, and thus you can eat more fiber-rich food, and take some laxative and laxative medicines if necessary. When hematuria occurs, do not be overly nervous. At this time, hematuria in most cases can soon stop on its own, you can drink more water, keep the bowel movement can be. However, if the hematuria is more serious, you need to go to the hospital immediately, without delay. Usually the hematuria will get better after using some medicines to stop bleeding or after the urinary catheter is re-installed. There is another situation of hematuria after electrolysis, that is, although the color of urine is normal, there is always some blood at the beginning and the last part of each urination, which is also very normal and usually does not need special treatment. For a period of time after the electrolysis, some patients may feel that they have to urinate more often than before, and sometimes they may have the feeling that they cannot urinate soundly, which is even worse than before the surgery. This is mainly because the wound in the urethra needs some time to heal, and before healing, the wound is more sensitive to stimuli such as urine, so frequent urination, urgency, and painful urination may occur. However, this situation is not exactly the same mechanism as the frequency and urgency of urination before the operation, with the slow healing of the wound, it will gradually get better, and it usually takes 1~2 months. After surgery, when the catheter is removed for the first time (usually 3~5 days after surgery), a few patients may not be able to pass urine, which may be due to the weakness of bladder contraction, or the serious edema of the wound surface, and the pathway of urinary evacuation is still not quite smooth. This requires re-insertion of the catheter, rest for a few days, and some medication, usually can be improved. There are also some patients who are reluctant to urinate for fear of pain after removal of the catheter, which may overfill the bladder and even lead to acute urinary retention and re-catheterization. In the outpatient review after the electrodes, the patient’s urine routine examination will show a certain number of white blood cells and red blood cells, but they do not feel any discomfort. At this time, if no other abnormalities are found, there is no need for special treatment, drink more water, increase the urine volume, and flush can be. Do not add any mental burden to yourself, and do not need to take a lot of antibiotic treatment. In addition, in the short term after surgery (2~3 months), try not to ride a bicycle, because this will press the prostate surgery site, and may cause bleeding of the prostate wound. It is also inappropriate to take a hot bath during this period, as this will cause the blood vessels in the prostate to dilate and the blood circulation to speed up, increasing the risk of bleeding.
