What methods can confirm the diagnosis of bladder cancer Experts say that the simplest test for bladder cancer is the three-cup urine test, which observes the time when hematuria occurs during the whole urination process, and depending on the time of hematuria, the approximate site of the urinary tract disease can be determined. If the hematuria appears at the end of urination, the site of the disease is in the bladder, while painless hematuria is an early warning of bladder cancer.
Ultrasound examination is convenient and easy to perform, but if the diameter of tumor is less than 0.5 cm, it often has false negative, so it has limited practical value for early diagnosis CT examination can determine the degree of tumor infiltration and whether the lymph nodes are metastatic, and it can see the advanced lesions clearly, but it is not very practical for auxiliary diagnosis of bladder cancer. Urine sedimentation cytology examination and serum marker examination of bladder tumor can also be done, and these examinations are helpful for the auxiliary diagnosis of bladder cancer.
Cystoscopy is the most important method to confirm the diagnosis of bladder cancer. Through the examination, it can clarify whether there is a bladder cancer tumor and the number, size and shape of the cancer tumor as well as whether there is a tip and a base, and random biopsy can be performed. Cystoscopy can be used both for early diagnosis of bladder cancer and to help in the initial formulation of surgical treatment.
If the cancer is found to be small, less in number, more superficial and with a tip during cystoscopy, then transurethral electrocautery or electrodesiccation of bladder tumor can be done and bladder cancer can be cured. If the tumor is larger, has a wider base, has deeper infiltration or has metastasis, the scope of surgery should be determined by the doctor according to the situation. In conclusion, cystoscopy is of great value for the early diagnosis of bladder cancer and is also important for the formulation of treatment plan.
