No one who has suffered from bladder tumor will forget one engraved symptom – painless hematuria. Why does this phenomenon occur in bladder tumors? The reason is: bladder tumor has no envelope and often grows on the bladder wall like watercress or papilla. When we urinate, the tumor is squeezed and bleeds and blood is discharged with the urine, we will see the urine is washed like water or even bright red.
Bladder tumor is the most common urinary tract tumor. Clinically, about 50% of people over 40 years old with painless hematuria are caused by bladder tumors. Malignant accounts for 80%, more men than women. The etiology is complex and the cause is unknown in most patients.
The main manifestations are: 1. intermittent painless total hematuria, aggravated at the end of the day. 2.
2, tumor located in the bladder neck may have difficulty in urination, late stage may have urinary frequency, urinary urgency, pain, anemia and wasting and other symptoms.
It is not terrible to have bladder tumor, and the effect of surgical treatment is satisfactory. Usually superficial bladder tumor can be treated by transurethral electrodesiccation or transurethral electrocautery; infiltrative tumor should be decided by partial bladder resection, total bladder resection and intestinal bladder substitution or urinary diversion according to the size, location, number, classification and stage of tumor, and lymph node dissection should be performed if necessary. Bladder tumor has the characteristic of recurrence.
To prevent recurrence, we must take the following measures: 1. After surgery for early stage or superficial tumor, use drugs for bladder perfusion to prevent recurrence, among which BCG vaccine and Adriamycin have more satisfactory effect.
2, regular cystoscopy, early detection of recurrent tumors, tiny tumors immediately to electrocautery.
Bladder cancer is a common urological tumor. Any male aged >40 years old, with painless full course carnal hematuria and end aggravation, should be suspected as bladder tumor and should undergo comprehensive urinary system examination. Because of the intermittent nature of bleeding in this disease, it is important not to think that the disease has been cured and give up comprehensive systemic examination because of the temporary hemostasis by medication, so as to delay the diagnosis and treatment. Most of the bladder tumors are early mucosal layer tumors and should be treated by surgery as soon as possible after diagnosis. Cystoscopy and random biopsy should be done once in 3 months to half a year, and once a year after negative, and 5 times after negative is cured.
