The point of holding urine before cervix cancer.

The meaning of holding urine before cervix cancer.Peasure is a very important step in the treatment of cervical cancer, which is important for improving the accuracy of the treatment and reducing damage to normal tissue. Here are some of the general contents of the pedagogy about holding urine before cervix cancer is administered:1. Impact of holding urine on the location of the treatmentThe pelvic tumours, including cervical cancer, are affected by bladders during their treatment. The bladder is a cystic organ in the middle of the pelvic cavity, with different levels of abundance causing the tumours of the bladder itself, adjacent organs (e.g., intestines, uterus, rectums, etc.). When the bladder fills most of the pelvis, the empty part is filled with small intestines and other adjacent organs. Therefore, changes in bladder size not only result in the movement of target positions but also affect the distribution of doses in and around target areas.2. Effects of holding urine on dose distributionFilled bladders can push the small intestines in the direction of the abdomen, and keep some intestines away from the range of the target, thus reducing the dose to which the intestines are exposed. Studies have shown that when the charge in the bladder reached 300 ~350 ml, the radioactivity of V30, V40 and V45 decreased by 30 %, 38 % and 31 %, respectively, after passing through the bladder. This indicates that good bladder filling is one of the prerequisites for a good dose distribution.3. Effects of hold-up on the side effects of medical treatmentIn the course of radiotherapy, rays not only kill tumour cells but also harm normal tissue around the irradiated area. The holding of urine reduces the exposure to bladders, while squeezing the intestinal tract away from the irradiation area, reduces the exposure to the intestinal tract, thereby reducing the intestinal side-effects, as well as the side-effects of release. If you do not hold your urine or if you hold your urine in an unsatisfactory condition, the doses to the bladder and intestinal tract increase, and there may be signs of acute chronic radioactive bladderitis, such as urine frequency, urination, pain and even blood urine, bladder dentures, and symptoms of diarrhoea, defecation habits change and even defecation, and narrow intestinal tracts may be subject to surgical treatment.4. How to hold urinePatients need to excrete and excretion before they are located and discharged, and then drink a certain amount of water on a personal basis, bearing in mind the time of drinking, and then locate or undergo treatment based on the patient ‘ s subjective perception (if there is a sense of urination, a sense of urination on the upper edge of the conjunctive bone). The patient is generally advised to excrete and then drink approximately 500 ml before locating and retraining, and to measure the size of the bladder when it is felt that it is in an emergency, and if the results do not reach 300 ml, to continue to increase the urine until 300 ml or above is CT-based.Consistency of holding urineThe pelvic tumour precision treatment should ensure that the bladder is filled with better and consistent throughout the treatment. The amount of urine held is as high as possible at the first location to ensure that the organs within the pelvis are located in the same position, thus ensuring the accuracy of radiotherapy.Scientific management of hold-up of urinePrior to treatment, patients can measure bladder sizes on several occasions with a bladder capacity measure until the amount of urine is close to the values recorded at the CT location, which can effectively reduce the deviation of the surrounding structure caused by changes in bladder size, improve the accuracy of the treatment and mitigate the adverse effects of the discharge.Concluding remarksCervical cancer is critical to ensuring the accuracy of treatment and to reducing side effects. Patients should follow the guidance of a doctor and conduct scientific urine stifling to improve treatment and quality of life.
