The 83-year-old Li was diagnosed with bladder tumor due to hematuria, and the doctor recommended that Li undergo a radical total cystectomy, which was thundering when he heard the news of “cancer”, and then he heard the recommendation to remove the bladder, which was even more unacceptable to Li – without a bladder, urine would flow out of his body all the time. Not only would he have to guard his urine bag every day to prevent urine from leaking out, but he would also be unable to take a shower and wipe his body, and he would not be able to go out to visit friends or relatives, and the “stench of urine” he would emit would definitely make people shy away from him. The radical total cystectomy that Lao Li needs to undergo is a surgical procedure to treat some bladder tumors that are multiple, recurrent and have a high risk of metastasis. The surgery requires the removal of the patient’s entire bladder, including the prostate gland in men, the seminal vesicles and part of the vaginal wall in women, and since the bladder is the body’s urinary storage and excretion organ, the bladder must be surgically re-established to drain urine outside the body. There are many clinical routes of urine drainage after total cystectomy, which can be broadly divided into two categories: external drainage and internal drainage. External drainage means direct drainage of urine outside the body and continuous collection of urine through an extracorporeal urine collection device, and there are two most commonly used methods: the ureteral skin fistula method and the ileal output tract method. The former directly transfers the ureter from the posterior abdominal wall to the anterior abdominal wall, and through the stoma in the anterior abdominal wall, the urine produced by the kidney is directly drained to the outside of the body through the ureter; the latter involves first cutting a section of small intestine, and then connecting the ureter to one end of this section of small intestine, and subsequently draining the other end of the small intestine from the anterior abdominal wall, and the urine produced by the kidney needs to pass through the ureter, the small intestine, and then out of the body, although the ileal output tract is more complicated and also Although the ileal outlet is more complicated and an additional section of small intestine needs to be cut, it is less prone to complications such as inability to pull the ureter out of the abdominal wall, contracture of the skin fistula, and retrograde pyel infection, which are common in ureteroscopic fistulas. Internal drainage, on the other hand, requires the use of part of the GI tract as a urinary reservoir to remove urine from the body via the GI tract via the internal route. The earliest form of internal drainage was “urinary-fecal coarctation,” in which urine was drained directly into the intestine, where it was stored, and then the patient drained the urine through the anus in the form of a bowel movement, but this method has been largely eliminated due to complications. There are two most popular internal drainage methods: one is the neobladder, in which a longer section of the digestive tract (about 4-5 times the length of the ileal output tract) is first cut and folded and reshaped into a spherical shape to serve as a urinary bladder or “artificial bladder”, and the ureter and urethra are then connected to this bladder. This approach allows the patient to maintain a physiological urinary pattern after total cystectomy, but the risk of recurrence of tumors in the urethra makes this type of surgery more selective for the patient, and because the contraction force of the intestinal wall is much weaker than that of the bladder, there are complications after reconstruction of the new bladder such as incomplete urinary emptying leading to renal impairment and urinary incontinence. The major difference with the new bladder is that the intestinal urinary bladder is not connected to the urethra, but through the appendix or another section of thin cut intestinal tube, the urinary bladder is connected to the abdominal wall or umbilical port, and the urine produced by the kidneys is normally stored in the urinary bladder and does not leak out from the abdominal wall, while the patient needs to insert a catheter at regular intervals (usually 2-3 hours) through the umbilical port or the stoma in the abdominal wall to drain the urine in the “artificial bladder The patient needs to have a catheter inserted at regular intervals (usually 3-3 hours) through the umbilical or abdominal wall stoma to drain the urine from the “artificial bladder. It is evident that modern medicine has devised many alternative methods for patients undergoing total cystectomy, and although these methods vary widely and have their own advantages and disadvantages, each patient can only receive one of these methods, and usually the urologist will choose a procedure that is most appropriate for the patient based on the patient’s disease status, lifestyle, and concomitant diseases, and sometimes the surgeon will consult with the patient prior to surgery to determine the final Sometimes the surgeon will consult the patient before the procedure to determine the final means of urine drainage. After the doctor’s patient explanation and explanation of doubts, Lao Li calmed down and finally accepted the external drainage of the ileal output tract, considering that he was already over 80 years old and was not suitable to bear the blow of another long gastrointestinal resection. Although he had to wear a urine bag on his lower abdomen at all times after the surgery, he adapted to this method of urine collection over time, and jokingly said that he was “disconnected from the urinal and no longer had to look for a public toilet. In fact, after years of improvement and development, now used for urine drainage of disposable urine bags and skin fit tightly, as long as the urine bag does not leak, there will never be urine leakage, and will not emit “urine stink”, and the glue on the skin irritation is very small, rarely cause skin allergies or inflammation, while the effect is lasting and constant, generally a urine bag can be used for a week, and even patients wearing urine bags in the shower will not affect its service life. Now Lao Li has successfully passed the “break-in period” with the urine bag, the urine bag around him did not add too much trouble and annoyance, Lao Li still enjoys the happy life in his old age, as before the surgery.
