Many elderly people choose to undergo cystostomy due to poor health, bladder will not contract, urethra severe narrowing, etc. This is a method of urinary diversion, through the suprapubic puncture of the bladder, the fistula tube is placed into the bladder, and the urine is directly drained out of the bladder. Fistula surgery solves the problem of the elderly not being able to urinate, but it’s not a one-off after fistula surgery, and there’s still a lot of attention to be paid. Only by strengthening the postoperative care, can we play the role of fistula and avoid the pain caused by complications to the elderly. Precautions are listed as follows: 1, regular replacement of the fistula tube. Generally the fistula tube should be replaced about once a month, this is very important. If it is not replaced for a long time, there will be many problems, such as infection, blockage, stones, and so on. I once met an old man who had left his fistula tube in place for more than a year and came to the hospital to ask for a replacement only when it became blocked. We found that the head of the fistula was wrapped with stones and could not be pulled out directly. We had to go into the operating room in the endoscopy of the stone crushed, before pulling out the original fistula tube, replaced with a new tube. 2, keep the skin at the fistula dry. The skin at the stoma is in contact with the stoma tube and is prone to redness, secretions, hyperplasia and other inflammatory reactions. Attention should be paid to local care, povidone-iodine disinfection 2-3 times a day, to keep the local dry, to prevent the inflammatory reaction from aggravating. 3, drink more water. Because of the small lumen of the indwelling fistula, if the amount of water is small, the urine will be easily blocked if it is concentrated. Drink more water appropriately, so that the urine dilution, flush the lumen of the urinary catheter, the chances of blockage will be reduced. 4, the emergence of fistula drainage flow significantly reduced timely medical care. Many elderly people who have undergone cystostomy are elderly, bedridden for a long time, unable to take care of themselves, and have difficulty in feeling and expressing themselves. If there is a blockage of the stoma tube, they often fail to inform their family members in a timely manner, which may lead to serious consequences. It is recommended that in this case, the family should pay special attention to the drainage of the fistula tube. 5, the fistula tube fixed indeed. The fistula tube must be fixed, when the elderly turn over, change the bed sheet should be especially careful, avoid the fistula tube pull out. 6, the fistula tube dislodged. Due to carelessness or leakage of the fistula balloon, the fistula may fall off. This situation should be dealt with in a timely manner in a hospital. There is a short period of time to put the fistula tube into the bladder through the original channel, if the time is too long, it is necessary to re-puncture fistula, bringing unnecessary pain to the elderly. 7, urinary frequency, urinary urgency and other discomforts. Some of the elderly in the replacement of fistula frequency, urinary urgency and other discomforts, should be timely communication with the doctor, to see if the fistula is placed in the prostate urethra due to stimulation. If this is the case should be promptly adjust the position of the tube. 8, cloudy urine, fever. If you find that the drainage out of the urine is cloudy, flocculent floaters, the elderly have a fever, loss of appetite and other circumstances, should think of the possibility of urinary tract infection. Please contact the doctor in time, combined with the physical condition of the elderly, urine bacterial culture or fungal culture, targeted application of antibacterial drugs. 9, in the daytime appropriate clip closed fistula, 2 hours or when the elderly feel suffocation open, so that the bladder to maintain a certain capacity, which can exercise the bladder function, to avoid the bladder function of waste continue to decline; in the evening do not clip closed fistula, so that the elderly and caregivers to rest. 10, come to the hospital to change the tube before letting the elderly drink 300-500ml, and clamp closed fistula tube 1-2 hours, so that the bladder is appropriately filled, convenient for the doctor to change the tube to determine whether the depth of the tube is appropriate, to avoid placing too deep or put in the position. In conclusion, after cystostomy should strengthen the care, to play this method of effective role, to avoid complications, so that the elderly to spend their twilight years peacefully.
