I. Who is one’s supervising physician Given the special nature of surgery, treatment is usually done by a treatment team whose member is the supervising physician, which can be confirmed by a bedside card and a photograph of the physician at work or by consulting the nurse. The supervising physician is the most knowledgeable and should generally be contacted for treatment problems, and only in emergencies can any physician in the department be called upon to handle the situation. As you can see, surgeons have almost daily surgical duties and may sometimes be in the operating room all day. It is important to communicate fully with the supervising physician during the daily morning check-in to understand the treatment and examination schedule for the day. In addition, in order to ensure sufficient time for medical activities, it is recommended to have a more regular family member in addition to the patient to communicate with the doctor in charge, which will be more conducive to diagnosis and treatment, as well as to inform other family members who come to visit the patient. (1) the current use of urinary catheters for the balloon ureter, can better fix the ureter so that it is not easy to get out, usually the balloon is stuck in the triangle of the bladder, which is where the feeling of urination, the stimulation of the balloon will make some patients have the feeling of wanting to urinate or even stool, in fact, in most cases as long as the ureter is open, there is not much urine in the bladder, that is a feeling. On the other hand, care should be taken to protect the urethra from being stretched, not to mention forcibly removing the urethra, which can cause damage by tearing the urethra due to the pressure of the air sac. (2) Normally, the urethra produces some secretions, which are normally washed away by urine. After leaving the catheter for a period of time, due to the lack of urine flushing and stimulation of the catheter, a colorless, off-white or yellowish discharge will appear from the urethra, which is often mistaken for urethral discharge, and there is no need to be alarmed and consult the nurse in charge. (4) The placement of the catheter is necessary for treatment, and the length of placement is determined by the condition, sometimes contradictory. The catheter cannot be left in place for a long time, and sometimes it can cause urinary tract infections and is also the cause of urethral stricture. Whether the catheter needs to be clamped or not is determined by the condition and is done according to the request of the doctor in charge. (5) After removal of the catheter, many people will have symptoms of urethral irritation, i.e., frequent, urgent and painful urination, and some will have hematuria, which usually does not require special treatment. There is no need to be nervous, drink more water, 4000 ML of water per day, and observe diligently. III. What is the purpose of continuous bladder irrigation The bladder irrigation process can remove blood and pus from the bladder, prevent bleeding from forming blood clots and blocking the urinary catheter, ensure smooth drainage, reduce pain and irritation, prevent infection, and facilitate recovery of bladder function. Fourth, attention should be paid to the flushing process (1) Aseptic operation to prevent infection. (2) During the flushing process, observe whether the flushing fluid and the drainage flow are as much as each other, observe whether it is unobstructed, and whether the patient has pain or small abdominal discomfort. (3) Observe the color of the drainage fluid. Hematuria will occur after all urological procedures, and the amount of bleeding is different for each patient and each procedure, so there is no need to panic. The flushing speed is not constant, but can be adjusted according to the color of the drainage fluid. When the color of the flushing fluid is dark, adjust the drip rate faster, and when it is lighter, adjust it slower to keep the urinary catheter open and not to form blood clots to block the tube.
